Tackling Dengue fever by turning female mosquitoes into males

Genetic engineering appears to be the key for delivering mosquito control, according to new research. Scientists have successfully converted female mosquitoes into non-biting males.

Bacteria-infected Brazilian mosquitoes pack a punch in dengue fight

Rio De Janeiro - Dengue-resistant mosquitoes breed in a Rio de Janeiro laboratory, producing offspring infected with bacteria packing a punch in the fight against the deadly virus, which is exploding across Brazil this year.

Q&A: How Mozambique is preparing for the malaria threat Special

As the floodwaters recede after Cyclone Idai, Doctors Without Borders' response to the natural disaster is preparing for the next health threat in Mozambique: malaria. To gain an insight of what is happening on the ground, we spoke with a malaria expert.

Millions of infected Brazilian mosquitoes to tackle dengue

Rio De Janeiro - Brazilian scientists on Tuesday began to unleash the first of millions of mosquitoes infected with a bacteria meant to prevent the insects from transmitting the dengue virus to humans.

One million Gin and Tonics for World Malaria Day

London - The company Fever Tree has announced it will be raising money for "Malaria No More", which is part of World Malaria Day, by donating 20 pence from its tonic water sales to the cause.

Mosquito spit may limit Dengue virus transmission

A key transmission factor with many viral diseases carried by mosquitoes is the saliva of the insects. A new finding, however, suggests that saliva can also help to prevent viral transfer, particularly Dengue virus.

Essential Science: West Nile virus causes memory loss

One of the lasting effects of West Nile virus, for some sufferers, is neurological problems including memory loss. A new study links this to an immune reaction.

New drug slows down rate of Zika infection

A science team have demonstrated that an experimental antiviral drug, designed for use against hepatitis C, can slow down the development of Zika in mice. Further studies will be undertaken to demonstrate the effectiveness in people.

WHO aims to wipe out malaria within two decades

Geneva - The World health Organization (WHO) is aiming to eliminate malaria from the planet by 2030. The United Nations health agency thinks that this feat is achievable, provided resources are provided by world governments.

New model for predicting Zika virus infection rates

Zika virus disease is easily transmitted. However, in the majority of people the disease is asymptomatic — symptoms appear in only one in four people, mostly as a mild fever. To find out why, a new study has been running.

New malaria parasite weakness detected

Scientists report that a weakness with the parasite responsible for the cause of malaria has been detected, based on the development of the parasite being based on its ability to extract genetic material.

Mutant mosquitoes to be deployed to stop Zika outbreak in Brazil

A Brazilian town plans to release millions of genetically modified mosquitoes to suppress the wild mosquito population responsible for Zika and Dengue outbreaks.

Chikungunya virus can lead to brain infection

The virus chikungunya, transmitted by mosquitoes, could lead to a dangerous brain infection. Those at greatest risk are infants and those aged over 65. This is based on a new study into past incidences.

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.

Potential antimalarial drug made from algae

Scientists have used algae to produce a malaria parasite protein. When the algae-produced protein is paired with an immune-boosting cocktail, studies showed generated antibodies in mice were able to eliminate a mosquito infection.

Using bacteria to battle malaria as possible drug treatment

Uppsala - A newly discovered family of bacteria, found in malaria-carrying mosquitoes, could hold the key to fighting the parasitic disease.

Little risk of malaria making a species jump

If the goal of eliminating the most dangerous malaria-causing parasite is achieved, will another type associated with a different species take its place?

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.

Beneficial bacteria help fight malaria

Lisbonne - Specific bacterial components in the human gut can help trigger a natural defense mechanism that guards against malaria transmission. This has come from a new study.

New compound shows anti-malaria promise

New York - A newly developed anti-malarial compound can trigger the immune system into rapidly destroying red blood cells infected with the malaria parasite and, at the same time, leave healthy blood cells intact.

Why do some mosquitoes carry malaria?

Researchers have genetically mapped 16 Anopheles mosquito species. Anopheles mosquitoes transmit human malaria parasites. Scientists are curious to understand why only a few dozen of the 500 different Anopheles species worldwide transmit malaria.

Chagas disease emerging as U.S. public health threat

Chagas disease - a stealthy parasitic infection that can lead to severe heart disease and death, is spreading in the U.S. Scientists argue that policy makers need to treat the issue seriously.

Dengue fever vaccine may actually increase prevalence

Scientists caution that such dengue fever vaccines will probably cause temporary but significant spikes in the disease in the years after they are first used, according to a new report.

Rise in drug resistant malaria

Washington - A new study indicates that drug-resistant malaria is spreading in South East Asia, and that it has now reached the Cambodia-Thailand border.

Solano County reports first case of potentially deadly virus

Fairfield - Health officials in the San Francisco Bay Area county of Solano confirmed last week that a resident had contracted West Nile virus.

Bacterial infection could help to fight malaria

Perugia - A bacterial infection in two species of Anopheles mosquitoes (called Wolbachia) appears to reduce the incidence of pathogen infections in mosquitoes and has the potential to be used in controlling malaria-transmitting mosquito populations.

Protein discovery could help prevent malaria deaths

Stockholm - Malaria can be mild or deadly. However, there is no way to tell which patients are at risk of developing more dangerous forms of the disease. New research suggests that different proteins affect the seriousness of the disease.

Chikungunya virus gallops across Caribbean; may hit United States

Oranjestad - Chikungunya virus is spread by mosquitoes and has been galloping across the Caribbean. Experts say that it's likely to hit the U.S.

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.

Malaria cases in U.S. at 40-year high

The number of malaria cases in the US has reached a 40-year high, with 1,925 cases reported in 2011 — the highest number since 1971.
