Mowing detention basins increases West Nile virus risk

Incidences of West Nile virus and the association of the disease with mosquitoes can be enhanced if mowers are taken to water detention basins, a study conducted in Central Illinois (U.S.) has revealed.

Repeated infections of mosquitoes makes malaria worse

If a mosquito gets re-infected with the parasite that causes malaria then evidence suggest that the parasites become more harmful to the next host. This is to do with multiple infections of different parasites.

New way to forecast West Nile Virus outbreaks

A new study has correlated weather conditions and the incidences of West Nile virus disease in the U.S. This could lead to a new means for predicting outbreaks and tracking the spread of the disease.

How Viagra can prevent malaria transmission

Viagra, the well-known drug for men with sexual problems, may have another use: fighting the malaria parasite. This is, in all seriousness, by increasing the stiffness of infected erythrocytes (red blood cells).

Why do some people attract mosquitoes more than others?

Been sitting outside with a group and wondered why some people are bitten more often than others by mosquitoes? The answer lies in the genes, resulting in some people being ‘super magnets’ for the buzzing nuisances.

Malaria cells produce odors that attract mosquitoes

Malaria causing parasites produce chemical compounds that give off odors. These odors attract mosquitoes to come and bite an infected animal, thereby ensuring the cycle of infection continues.

Disease carrying mosquitoes could reach the U.K.

Mosquitoes carrying "tropical diseases" could become widespread across the U.K. over the next 20 or 30 years. This is assuming that European temperatures continue to rise.

Resistant malaria moves closer to India border

Parasites resistant to the antimalarial drug artemisinin are spreading through mosquitoes. A new study shows that mosquitoes carrying these parasites are in Myanmar and are heading to the India border.

Messing with 'Mother Nature' — Here comes DNA-altered mosquitoes

Mosquitoes are carriers of some horrible diseases like Dengue and chikungunya, to name just a few. A UK company has developed a genetically-mosified mosquito that may take care of the problem, reducing mosquito populations. But not everyone is happy.

Misuse of antibiotics can lead to increase in malaria

New research suggests that mosquitoes that consume penicillin and streptomycin-laced human blood pick up malaria more easily.

Understanding mosquito feeding, to avoid disease spread

Biologists have discovered that mosquitoes bite male birds twice as often as they bite females. The same is true with people: mosquitoes bite men more often than women. Knowing this could help to stop the insects from spreading viruses to people.

Chikungunya viral infections in France

Montpellier - The World Health Organization (WHO) has reported on four locally acquired cases of the virus in France: four members of the same family in Montpellier.

Brazil launches 'good mosquitoes' to fight Dengue fever

Rio De Janeiro - Brazilian scientists, based in Rio de Janeiro, have released thousands of mosquitoes infected with bacteria that suppress dengue fever.

How chikungunya virus spreads

A study has revealed that chikungunya virus is transmitted through a three-way interaction that relates to viral strain, mosquito genotype, and ambient temperature.

First Chikungunya case contracted in U.S.

Miami - A Florida man has become the first U.S. resident who has not recently traveled outside the country to be diagnosed with an infection from the mosquito-borne virus chikungunya.

Mosquito trap prompts bomb investigation

Rock Springs - A bomb squad was called in to investigate a suspicious device found inside a Wyoming power plant early Wednesday morning. The device in question turned out to be just a common trap used for mosquitoes.

Mosquitoes attracted by odor

Mice infected with a malaria-causing parasite emit odors that are more attractive to malaria-transmitting mosquitoes, according to new research.

Tracking chikungunya virus across the globe

Paris - As chikungunya virus spreads across the Caribbean, scientists are attempting to work out the virus’s next steps and understand its partnership with mosquitoes.

Call for horses to be protected from mosquitoes

A leading veterinarian in the U.S. advises that horses should be protected from mosquitoes to in order to protect the horse and people from West Nile virus, especially during the heavy infection season in mid to late summer.

Genetically engineering mosquitoes to combat malaria

A science group has proposed that introducing genetic engineering to eliminate the population of female mosquitoes is key to fighting malaria. Other scientists have expressed concerns about the ethics of species elimination.

New target for treating Dengue fever

New research may help scientists develop treatments for Dengue fever, West Nile virus, yellow fever, Japanese encephalitis and other disease-causing viruses.

Why are mosquitoes attracted to people?

Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to people by smelling the carbon dioxide we exhale. This is the outcome of a new study.

Clues offered about Dengue fever

Dengue fever and West Nile fever are mosquito-borne diseases that affect hundreds of millions of people worldwide each year. However, there is no real protection against either of the related viruses. Scientists have been looking into the issue.

Searching for a new way to halt malaria

A research team have identified a way to stop malaria parasites from multiplying. It is hoped that this could become the basis of a new treatment.

How to make people 'invisible' to mosquitoes

Scientists think that it is possible to make an "invisibility cloak"’ to protect people against the blood-sucking insects. The basis of the cloak is the drug used in illegal "party pills."

New antimalarial drugs in development

Lisbon - Researchers have discovered a new class of highly potent antimalarial compounds. These chemicals, developed to fight cancer, appear to be able to kill the malaria causing parasite.

Successful project delivers malaria nets to Ghana

Accra - The Promoting Malaria Prevention and Treatment (ProMPT) Project has proposed a model for distributing over 12 million mosquito nets to prevent malaria in Ghana.

Chimps contract malaria at the same rate as people

Chimpanzees have been studied for the first time relation to the incidences of malaria. The conclusion is that chimps can contract malaria just as easily as people and have similar survival rates if untreated.

How much dengue virus is needed to infect a person?

It is well established that dengue fever is spread by mosquitoes. But just how much of the virus is needed and when are mosquitoes most infectious? New research answers these questions.

Could climate change bring malaria to the UK?

Epidemiologists are calling on the government to take action against the growing threat that mosquito-borne diseases, including potentially fatal malaria, could soon arrive in the UK.
