General

What is the difference between the the BG-Mosquitaire trap, the BG-GAT, and the BG-Home?

Our traps catch mosquitoes in different stages of their development and are made for mosquito control outdoors and indoors.

While the BG-Mosquitaire targets mosquitoes that are seeking a host and want to bite you, the BG-GAT targets tiger mosquitoes that are looking for a place to lay their eggs. Each egg-laying female that is trapped can eliminate 30-300 offspring from the next generation and prevent the potential for disease transmission from virus-infected mosquitoes. With these two strategies, you can reduce biting pressure as well as the next generation of tiger mosquitoes.

Of course, mosquitoes are not only found outdoors, as they also enter the house. In this case, the BG-Home indoor trap can help: It captures tiger mosquitoes and other flying pest insects inside the house.

Should you want to increase your outdoor catch rates even further, the best solution is provided by the BG-Mosquitaire with CO2. Our BG-Booster allows you to add CO2 to your BG-Mosquitaire from a CO2 cylinder. The addition of CO2 makes the BG-Mosquitaire even more attractive for a wide range of mosquitoes including flood water or dawn biting mosquitoes and can multiply the catch rate of tiger mosquitoes by 10.

To achieve the best mosquito protection in your garden and inside your home, we recommend using the Biogents Trap System. This consists of one BG-Mosquitaire + two BG-GATs + one BG-Home.

Where is the difference between the BG-Mosquitaire trap and the BG-Sentinel/BG-Pro trap?

There is no difference concerning the catching rate, but only in the construction. They use the same patented technology and the same electrical components. The BG-Sentinel and the BG-Pro traps are designed for scientists and researchers to monitor mosquito populations. It is made out of a light and easily transportable material. The BG-Mosquitaire is designed to be used permanently outdoors and is more robust.

Where is the difference between the basic traps and the CO2 versions (e.g., BG-Mosquitaire and BG-Mosquitaire CO2)?

The basic traps (without CO2) only catch tiger mosquitoes (Aedes albopictus, Aedes aegypti). The CO2 versions attract all kinds of species (e.g., Culex). They also have a higher catching rate regarding tiger mosquitoes.

Trap operation

Where should I place the trap?

The best place to position our outdoor traps is somewhere shady, humid, and wind-protected, where mosquitoes like to rest and breed. To find the best position and to get the highest catch rates, test different locations! A few meters can make a big difference. To find the best place for our BG-Home indoor trap, find the place where mosquitoes enter the house, or find a dark corner on the floor or near plants. It is important to make sure that the ventilator of the trap runs 24 hours a day and especially if you are not at home. More info: https://eu.biogents.com/positioning-application/

How far should I distance the trap from human beings?

We recommend maintaining a distance of at least 5m between people and the trap. A human will always be more attractive than even the best trap, so the trap shouldn’t be placed directly on stone, but in the greenery nearby; in a shady, humid, and wind-protected location where mosquitoes like to rest and breed.

Is the trap rainproof? Can I leave traps out in the rain? Will the electrical part and the attractant still work?

Our outdoor products are all rainproof, however, we recommend unplugging the BG-Mosquitaire in the case of a thunderstorm. The trap will not be damaged by the rain and the ventilator will continue to run but since mosquitoes do not fly in heavy rain, the trap will not catch as many mosquitoes as usual. Also, the catch rate will be reduced until the white upper part and gauze are dry again. Please consider that the BG-Home is an indoor trap and should not be used outdoors.

What size area does the BG-Mosquitaire cover?

There are many different criteria that influence the catch rate such as mosquito population, breeding waters, resting places, coppice, climate, surroundings, etc. As such, it’s hard to give a reliable indicator. Depending on whether your garden has a lot of plants or not, you may need a different number of traps for the same area. But, as a general rule, one BG-Mosquitaire trap covers roughly the area of one average-sized house and garden. Mosquitoes often fly around their surroundings in search of a host, and sooner or later they will pass by a well-placed trap running 24/7.

How many traps do I need to put in my garden?

One good trap in the right place is more effective than many traps in the wrong place. The catch area of a given trap depends primarily on wind direction, but also on many other factors. It is very important to place the trap in the vicinity of mosquito resting places such as bushes and greenery.
If you have several resting areas around your house at least 20m apart, it might be necessary to place extra traps.
Try a single trap first, and you will soon find out if you need more, or if you want to add CO2 to increase your catch.

When will the trap begin to be effective?

The Biogents trapping method needs about one week time to start working properly. The traps (“artificial human beings”) are permanently present as opposed to human beings, and they catch wandering mosquitoes, so the active population (and its reproduction rate) will be kept down in the long run.

Is there a possibility to run the traps with batteries or solar power?

The BG-Mosquitaire, BG-Mosquitaire CO2 and the BG-Sentinel can be run with 12 V motorcycle or car batteries or solar panels (30-50 W). Be aware that a mosquito trap should be placed in a shady area, while the solar panel has to be in a sunny place. The Biogents Team is constantly researching and developing to produce even better solutions in the future. In the meantime, you can use our extension cable to be able to plug the trap in, but still have the best possible positioning for it.

The BG-Pro for researchers can also run on 5 V with a  powerbank for a limited time.

When do I have to install the traps in my garden?

The sooner you can activate the trap the better. Around springtime, or when temperatures rise above 15° C. By using the trap, you will be able to maintain the mosquito population as low as possible by catching every single mosquito as soon as possible in the season, where each one could lay up to 300 eggs. Those eggs would turn in potential biting mosquitoes, reproduce and increase the mosquito population exponentially. A mosquito that you find in your garden probably hatched within 200 m of your home.

How and when do I change the catch bags of the outdoor suction traps (BG-Mosquitaire)?

We recommend changing bags regularly, at least every time you change the attractant. A bag that is clogged with captured mosquitoes does not allow the fan to suck properly and makes the trap less effective. The steps for changing the catch bag can be found in the instructions manual that is provided in the packaging. In trade, a catch net, a funnel net, and the BG-Sweetscent are available in our webshop.

 

How can I ensure that the mosquitoes caught in the catch bag of the BG-Mosquitaire and are still alive do not fly out of the bag while I am changing it?

Slightly pull the intake funnel out of the trap so that the catch bag is still within the suction current of the fan. Pull the catch bag off the funnel net, and simultaneously tighten the cord of the bag so it is shut. You can find these directions in the instructions manual that is provided in the packaging.

How and when is the gauze on the top of the trap changed?

The gauze should be changed when it has become dirty and when there is no longer a strong color contrast between it and the intake funnel. Additionally, a dirty gauze does not allow sufficient airflow through. The steps for changing the gauze can be found in the instructions manual that is provided in the packaging, or see downloads at the top left of the page. In trade, the gauze, the Biogents Sweetscent, a catch bag, and a funnel net is available in our webshop.

Where should I store the trap during the winter?

The best location for storage is somewhere enclosed and not exposed to winter weather. Do not store the trap below freezing point for an extended period of time.

How many mosquitoes did the trap catch?

Sometimes it is difficult to estimate the amount of caught mosquitoes.
The following images give you an impression of the amount of caught mosquitoes:

80,000 mosquitoes caught with Biogents mosquito traps
80,000 mosquitoes, caught within one week at the Starnberger See (lake in Bavaria, Germany), 2013

Will I be able to kill all the mosquitoes?

The trap itself doesn’t kill mosquitoes, but they dehydrate and die once they are caught in the catch bag.

Looking at the whole population of mosquitoes in your area, you will be able to decrease the local population.However, you will not eliminate the whole population, because there will always be some breeding areas in the neighborhood where fresh mosquitoes can hatch. In general, the wider the area is that is covered with the traps, the better the effect. Therefore, to join forces with neighbors is a good idea!

How many mosquitoes will I trap per day?

It is amazing how many mosquitoes can be caught in a short time. It depends on the size of the mosquito population where you are. If precautionary measures (e.g., destruction of breeding sites) have been correctly performed, the number of mosquitoes in the trap should decrease over the course of the season.

Carbon Dioxide – CO2

Where can I get a gas cylinder?

It can be acquired or rented at drink retailers or bottle depots for a deposit. A door-to-door delivery service may also be possible in some locations.

Where can I get a CO2-bottle in the USA?

Unfortunately, we do not have a cooperation with a gas company in the states, yet; however, the following sites offer competitive renting prices:
Roberts Oxygen: http://www.robertsoxygen.com/
US Home Brewing Organization: http://brew.burp.org/Brewing/CO2SourcesUpdated.aspx

Is there a special gas tank you recommend? How often does it have to be changed?

For our CO2 traps, we recommend using a 10 kg gas cylinder. However, you could also use 5, 6, 10, or 20 kg if you prefer. These can be acquired or rented at drink retailers or bottle depots for a deposit. A door-to-door delivery service may also be possible in some locations. How often you need to change the tank depends on: 1. what size you use and 2. which release rate of CO2 you use. Our CO2 traps give you the option of deciding between two flow rates: standard and high. This allows you to adapt the release of CO2 to the mosquito situation. In the product catalog, you will find a chart which compares the two flow rates, and shows how long a 5 kg and 10 kg gas tank lasts (in days).

Is it possible to run several traps with a CO2 cylinder at the same time?

Yes, it is possible to run everal traps with a CO2 cylinder at the same time by connecting the CO2 tubes with Y-connectors. Please note that the pressure of the CO2 bottle must be increased by 0.5 kg/day for each additional trap.

Example: One single trap requires 0.5 kg/day. If you run two traps, the pressure must be increased to 1 kg/day. With three traps at the same time, the pressure must be 1.5 kg/day (inner scale of the pressure reducing regulator).

In addition, to ensure the correct amount of CO2 supply for each trap, our red sinter filter must be fitted to the CO2 emitter nozzle on each trap. If the sinter filter is not placed at the nozzle, the length of the CO2 tube from the CO2 bottle to each trap must be the same, otherwise the trap with the longer tube will not get enough CO2.

Connecting several mosquito traps to one gas bottle

BG-Sweetscent – artificial human skin scent

How many times do I need to refill the artificial human scent and the sticky cards during the season?

All our traps need regular refilling to function properly throughout the season.

One BG-Sweetscent sachet in the BG-Mosquitaire trap is effective for up to two months. After that, it should be replaced. BG-Sweetscents are also available as a season pack for six months (3×2 months).

The BG-Homescent must be replaced every month in the BG-Home.

The sticky card in the BG-GAT should be replaced every two weeks or as soon as the card doesn’t stick anymore. The sticky cards are available in sets of 10.

The BG-Lure for professionals lasts up to five months (no matter if the trap runs 12 or 24 hours a day).

What role does the BG-Sweetscent play?

The BG-Sweetscent is a three component scent imitator that increases the efficacy of the BG-Mosquitaire trap in addition to visual signals and artificially generated air plumes. The patented composition of the BG-Sweetscent imitates the composition of human skin.

What is particular about BG-Sweetscent?

The BG-Sweetscent is a patented three component scent imitator that is specialized for use in the BG-Mosquitaire and the BG-Mosquitito trap and in particular against tiger mosquitoes. Therefore, it is only highly effective in combination with the BG-Mosquitaire and the BG-Mosquitito trap. Each of the three components imitates a part of the main components of the human skin. The particular light and permeable packaging of the BG-Sweetscent guarantees an optimal timed release of the scent into the surroundings.

Why does the attractant smell bad?

A major component of the Biogents suction trap attraction mechanism is a patented scent dispenser. It fills the upward-moving air that leaves the trap around the suction funnel with an artificial human skin scent. The dispensers release small amounts of substances that are also given off by human skin (by sweating). The development of an artificial human scent represents a huge milestone in over 16 years of mosquito research. It is a patented three-component scent imitator. The effect of our attractants has been measured and is scientifically proven. After opening a Biogents attractant, the smell remains relatively strong for the first three days. During this time, the odor is normally too strong for mosquitoes, so optimum attraction levels are usually only reached about three days after opening. From then on, odor release is lower, but remains constant.

For users of the BG-Home indoor trap, the smell of the BG-Homescent might be too strong to be used indoors during the first few days after opening a new pack. In this case, we recommend placing the sachets outdoors for two or three days to let the strong initial odor fade away. The trap can be used without an attractant in the meantime.

Is the BG-Sweetscent the actual "secret of success" for the BG-Mosquitaire trap? Would other mosquito traps obtain the same results as the BG-Mosquitaire if I used a BG-Sweetscent package with them?

Absolutely not. The BG-Sweetscent is specifically designed for the BG-Mosquitaire, and specialized for tiger mosquitoes. Therefore, it only yields high results in conjunction with the BG-Mosquitaire and BG-Mosquitito trap which has been proven multiple times.

How do I switch out the BG-Sweetscent package?

The BG-Sweetscent can be switched out in two simple steps. These steps can be found in the instructions manual that comes in the packaging.

How do I change the BG-Sweetscent?

The BG-Sweetscent can be changed in two simple steps. The steps can be found in the instructions manual that was provided in the packaging.

I have the impression that the BG-Sweetscent smell evaporates earlier than suggested. Should I exchange the BG-Sweetscent before the course of two months has expired?

No. The human nose becomes accustomed to the odor, and after a while one does not smell it anymore. In addition, it is possible that right after opening the package a large amount of the scent is released for a short amount of time. The scent is actually still there and very efficient throughout the two months. Therefore, you do not need to change the BG-Sweetscent before the course of two months has expired. However, you cannot wait longer than two months to change the BG-Sweetscent to ensure the effectiveness of the BG-Mosquitaire.

BG-Mosquitaire tiger mosquito trap

Why should I purchase Biogents traps instead of other mosquito traps that are on the market?

If you have tiger mosquitoes in your environment, then you should buy the BG-Mosquitaire trap. The BG-Mosquitaire was  specifically developed for use against tiger mosquitoes. Many international scientific studies that have been published in the top scientific journals of the world, and also presented at important scientific conventions, conclude that the BG-Mosquitaire trap catches a much higher amount of tiger mosquitoes than other mosquito traps do. Therefore, making it the best tiger mosquito trap. These publications can also be viewed on this website.

How is the BG-Mosquitaire trap specifically developed for tiger mosquitoes?

Worldwide, there are approximately 3000 different species of mosquitoes. Every different mosquito species responds differently to variable signals. Therefore, to maximize the catch of a particular species of mosquito, it is almost necessary to develop a trap that is specialized for that particular mosquito. Biogents achieved this by specializing on the most dangerous mosquito species: the tiger mosquitoes. The BG-Mosquitaire trap is so efficient, because it uses a patented combination of visual signals, artificially generated air plumes, and a patented 3-component scent imitator called the BG-Sweetscent that mimics human skin. These features were specifically developed for tiger mosquito. As for the catching of tiger mosquitoes, the BG-Mosquitaire trap is significantly better than all other mosquito traps.

Does the BG-Mosquitaire trap also catch other mosquitoes?

Typically, at least 80 % of the captured insects from the BG-Mosquitaire trap are tiger mosquitoes. The rest consists of a couple of other species of mosquitoes.

Does the BG-Mosquitaire trap catch other beneficial insects such as butterflies or lady bugs?

No, due to its specialization for tiger mosquitoes the BG-Mosquitaire trap does not catch any harmless or beneficial insects like butterflies or ladybugs, unlike other mosquito traps such as light traps. For that reason, the BG-Mosquitaire trap is exceptionally environmental friendly.

Why is the BG-Mosquitaire trap so big?

One type of signal that the tiger mosquitoes respond to is a visual signal. The size of the air plume that is produced from the trap as well as the size and shape of the trap itself play an important role. The BG-Mosquitaire trap utilizes both these signals to ideally mimic a human body which is why it has that distinct size and width. A smaller trap could not attain the same efficiency against mosquitoes.

What area does the BG-Mosquitaire trap cover?

One BG-Mosquitaire trap covers roughly the area of one medium-sized house and garden. Therefore take advantage of the fact that tiger mosquitoes are often flying around their surroundings on their quest for prey, and sooner or later they will pass by a well-placed trap.

On what basis can you claim that the BG-Mosquitaire trap is the best trap against tiger mosquitoes?

The BG-Mosquitaire trap has been specifically developed for use against tiger mosquitoes. Many international scientific studies that have been published in the top scientific journals of the world, and also presented at important scientific conventions conclude that the BG-Mosquitaire trap catches a much higher amount of tiger mosquitoes than other mosquito traps catch. These publications can also be viewed on this website.

What ties the BG-Mosquitaire trap to the BG-Sentinel trap?

The BG-Mosquitaire trap is specially designed for private household use, and is a further developed version of the BG-Sentinel trap, which has already proven its performance in the field multiple times. Scientists and mosquito specialists use the BG-Sentinel trap to catch tiger mosquitoes all around the world. Both the BG-Mosquitaire and the BG-Sentinel use the same highly effective catching mechanism with the only difference being that the handling and operation of the BG-Mosquitaire is easier.

Which customers already use Biogents tiger mosquito traps?

The largest and most familiar health authorities and research institutes of the world are using Biogents tiger mosquito traps. For example the Centers for Disease Control and Prevention from the USA, the Pasteur Institute in France, and the Cairns Tropical Public Health Unit Network in Australia are currently using Biogents traps.

How does the BG-Mosquitaire kill the captured tiger mosquitoes?

The tiger mosquitoes that are caught in the catch bag will die by drying out or dehydrating. Mosquitoes are dependent on a continuous supply of moisture. If they do not receive it, they will dry out and die.

How can I interpret the catch results of the trap? Last week, my trap only caught a couple of tiger mosquitoes.

This catch result is normal. It shows that tiger mosquitoes are in the vicinity, and a risk exists. To others the catch result is normal, because tiger mosquitoes are solitary and do not fly around in large swarms.
On the contrary, if you have absolutely no tiger mosquitoes in the catch bag of the BG-Mosquitaire trap, you can assume that there is not a tiger mosquito problem in your area at that moment unless the trap is positioned incorrectly. If you find a large amount of tiger mosquitoes in the catch bag of the BG-Mosquitaire trap, then there is an extremely large threat of tiger mosquitoes. Under these circumstances, we suggest using more than one BG-Mosquitaire trap. In any case, try to locate any possible breeding waters for the mosquitoes and empty them out. These water reservoirs are often found in flower pots, vases, buckets, water barrels, rain gutters, puddles, or even discarded cups that contain water. Using fine stones or sand as filling hinders the ability of the mosquito to be able to lay her eggs there in the future.

How safe is the BG-Mosquitaire trap for people, in particular for my small children?

The BG-Mosquitaire trap is completely safe for people and even small children, mainly because its does not use any pesticides or insecticides whatsoever. Obvious parts of the BG-Mosquitaire trap, for example the electrical connection or the fan, should not be within reach of children.

How safe is the BG-Mosquitaire trap for my pets?

The BG-Mosquitaire trap is also basically completely safe for pets, because there is absolutely no use of insecticides or pesticides. However, like children, pets should not be able to get to parts of the trap concerning the electrical connections or the fan of the BG-Mosquitaire trap

Does the BG-Mosquitaire use insecticides or pesticides?

No, the BG-Mosquitaire trap does not use any pesticides or insecticides whatsoever. This makes the trap very environmentally friendly and harmless to people, animals, pets, or other beneficial insects such as butterflies. The BG-Mosquitaire trap kills the captured mosquitoes only by dehydrating them.

Does the BG-Mosquitaire use CO2 ?

No, the BG-Mosquitaire trap does not use CO2 (carbon dioxide). Nevertheless, it is still highly effective. That is the big advantage of the BG-Mosquitaire trap in comparison to the majority of other mosquito traps, and makes the BG-Mosquitaire particularly so much easier with the handling. There are no bulky or potentially hazardous gas cylinders required.

What are the impacts of the BG-Mosquitaire trap on the environment?

The BG-Mosquitaire trap is very environmentally friendly, because

  • it does not trap any beneficial insects like butterflies
  • it does not use any pesticides or insecticides
  • it does not dispense CO2 (carbon dioxide)
  • it requires very little electricity to run
  • the BG-Sweetscent lasts a long time (roughly two months) and is refillable.

How much electricity does the BG-Mosquitaire trap need to run?

The BG-Mosquitaire trap needs only 4 Watts to run. That is less than an energy saving lamp requires. Because of the low energy consumption, the BG-Mosquitaire trap can be kept on the entire day without the need of a costly, elaborate timer.

How noisy is the BG-Mosquitaire trap?

The BG-Mosquitaire trap runs with ca. 50 decibel, measured in 1 meter distance of the trap.

Will the BG-Mosquitaire trap attract more tiger mosquitoes in my house or garden than there were before?

No, the BG-Mosquitaire trap only attracts and catches tiger mosquitoes that are patrolling around the vicinity.

Tiger mosquitoes and diseases

Why do mosquitoes bite?

Mosquitoes require blood to develop their fertilized eggs. The female mosquitoes produce the eggs; therefore, they seek out other life forms, for example humans, to bite and ingest their essential blood meal. Male mosquitoes do not lay the eggs.

What is particularly special about tiger mosquitoes?

First and foremost, the tiger mosquitoes are capable of transmitting serious diseases such as chikungunya and dengue fever. They obtain these viruses from one bite of an infected human. The virus then begins to proliferate inside the mosquito and after roughly ten days the mosquito can transmit the disease to other humans with only one bite.
In addition to these hazardous threats, the tiger mosquitoes distinguish themselves from other mosquitoes by being day feeders. They are abnormally aggressive and persistent. Tiger mosquitoes mainly do not fly in large swarms so they do not base success of the catch results on a large bulk of normal mosquitoes being caught, but rather on the actual number of tiger mosquitoes that are caught.

What are tiger mosquitoes attracted to?

Every mosquito species responds differently to the various signals that are emitted by their prey. Tiger mosquitoes react to a combination of particular visual signals, air plumes, and specific scents of the human skin. The BG-Mosquitaire trap is highly efficient, because it is specifically developed for tiger mosquitoes. It is a patented combination of visual signals, artificially generated air plumes, and a patented 3-component-scent that mimics human skin and further enhances the efficiency of the trap.

How do I recognize a tiger mosquito?

Tiger mosquitoes are not bigger than normal mosquitoes. In fact, they are often somewhat smaller. Their entire body is accentuated with white-silvery markings. Tiger mosquitoes are primarily recognized by their white-silvery stripes that begin between their eyes and continue down the middle of their back. Their hind legs also consist of the same color scheme so that they look like black and white ringed segments.

Where are tiger mosquitoes found?

Tiger mosquitoes are originally from Southeast Asia; however over the last 25 years, they have dispersed to many different regions around the world. Now you can find tiger mosquitoes in parts of Africa and the Americas. They are also prevalent in Europe where Italy is predominantly affected by them. There are very few regions in Italy where the tiger mosquitos have not yet made themselves at home.

Chikungunya and dengue fever

What do tiger mosquitoes have to do with diseases such as chikungunya and dengue fever?

Tiger mosquitoes can carry and transmit chikungunya and dengue fever. Because they are day active and often bite several people in a short period of time, they can be very dangerous vectors of disease.

Which regions have already had chikungunya and dengue fever epidemics?

In the tropical and sub-tropical bands of the earth (Southeast Asia, Indian Subcontinent, Africa, Latin America, etc.) there are chikungunya and dengue fever epidemics every year with millions of people infected. Dengue epidemics result in thousands of fatalities annually, and among them are notably small children. In 2007, Europe had its first outbreak of chikungunya in Italy with over 200 people infected.

How high is the risk for an outbreak in Europe?

The risk is indeed not exactly predictable, but with the distribution of the tiger mosquitoes throughout Europe and large parts of southern Europe having the necessary, adequate warm climates, it is only a matter of time before the viruses find their way through Europe. Every year hundreds of thousands of people travel to regions at risk and return back to their countries. In the last couple of years, hundreds of these travelers brought back chikungunya or dengue infections with them. It is now only a matter of time until the tiger mosquito will bite an infected person, and be able to transmit it to other individuals. Above all, chikungunya will be transmitted especially well by tiger mosquitoes.

Has Europe already been affected by such an epidemic?

Yes, Europe had its first outbreak of chikungunya fever in Ravenna, Italy, in 2007,  where more than 200 people were infected. In this case, the disease was introduced by a man who was infected while traveling in India when he returned back to Italy.

What are the symptoms and implications of chikungunya fever?

Chikungunya fever was first described in East Africa in the 1950s. Today, the distribution area of the disease reaches from eastern and southern Africa over the Indian Subcontinent and to Southeast Asia. Currently, the tiger mosquitoes and their close relatives, the yellow fever mosquitoes, which are not found in Europe, yet, are the only definite carriers of this virus that have been observed. Chikungunya is a word from the Tanzanian language that means “that which bends up” or “that which contorts”. The infected person normally has a rapidly increasing high fever. Severe joint and muscle pains cause extreme sensibility to where the individual can barely hold an erect position. The fever usually lasts only a couple of days. Normally, the illness simply runs its course, and the symptoms begin to subside after approximately one to two weeks unless complications occur. Consistent complications and deaths are rare. There is no vaccination currently available. After overcoming the disease, the individual is immune against chikungunya for life.

What are the symptoms and implications of dengue fever?

Dengue fever (also known as breakbone fever) is transmitted by the Asian tiger mosquito and the yellow fever mosquito. Regions of the greatest risk are Northern Australia, Southeast Asia, India, parts of Africa and parts of the Americas. In 90 % of the cases of infection, flu-like symptoms will be observed. In the other 10 % of the cases, a sudden high fever of up to 41° C is accompanied by a headache, limb, joint, and muscle pain and occasionally a skin rash. After approximately five days another fever attack usually follows, and then the recovery phase begins which can drag on for several weeks. The most severe form of dengue fever is the so-called dengue hemorrhagic fever (DHF), and it is associated with internal bleeding.

Each year more than ten million people will become infected with the dengue virus, and a hundred thousand people will develop the severe form, DHF. In most countries roughly 5 % of people suffering from DHF die. Where there are good medical services, this percentage drops to less than 1 %. Most of the fatalities occur among children and young adults.

Currently there is no vaccination against dengue fever. There are four closely related types of the dengue virus, and a sufferer of one type of dengue virus is not necessarily protected against the others.
