PAHO documents increase in dengue fever cases in Latin America

Countries in Latin America "are bracing this year for a particularly virulent outbreak of the mosquito-borne tropical disease" known as dengue fever, after reports show an increase in the number of cases recorded this year, Agence France-Presse reports. "The Pan-American Health Organization (PAHO) said so far it has logged some 146,000 cases in the first three months of the year, of which 79 have been fatal. This time last year there were some 79,000 cases of dengue reported, with 26 deaths," the news service writes.

Queensland rains and floods – boon or bane?

Warnings of floods and rains across Queensland have sparked fears related to Ross River fever among health authorities. Ross River fever is caused by a virus carried by a number of mosquito species. It is usually associated with joint pain and swelling that can last for weeks.

Global malaria investments saving lives, more funds needed

A new study linking funding increases in the global fight against malaria to a drop in deaths from the disease also shows that resources from donor governments still fall short of those needed for maximum impact against the world's fourth-biggest killer of children, according to a global health policy analyst at international aid agency World Vision.

Researchers identify a novel way to study species-specific reproductive behavior

Researchers at the California Institute of Technology (Caltech) and the University of California, San Diego (UCSD) have discovered that injecting a simple hormone into leeches creates a novel way to study how hormones and the nervous system work together to produce species-specific reproductive behavior.

International symposium to feature latest findings on vector-borne diseases in humans and plants

Leading insect vector biologists from around the world will gather at the University of California, Riverside for two days this month to discuss their latest research on vector-borne diseases in humans and plants.

Discovery may yield new strategies for blocking malaria transmission

Scientists studying the Anopheles gambiae mosquito - the main vector of malaria - have found that when the mosquito takes a blood meal, that act triggers two enzymes to form a network of crisscrossing proteins around the ingested blood.

Octenol compound aids mosquitoes in finding blood meal

The potentially deadly yellow-fever-transmitting Aedes aegypti mosquito detects the specific chemical structure of a compound called octenol as one way to find a mammalian host for a blood meal, Agricultural Research Service (ARS) scientists report.

Researchers take first step in development of vaccine against pregnancy-associated malaria

By managing to express the protein that enables red blood cells infected with the malaria agent Plasmodium falciparum to bind to the placenta and by deciphering its molecular mechanisms, a team of researchers from CNRS and the Institut Pasteur has taken an important first step in the development of a vaccine against pregnancy-associated malaria.

MASSIVEGOOD launched to enable travelers make contributions towards major global health causes

UN Secretary-General Ban Ki-moon and President Bill Clinton join today with international recording artists will.i.am and David Guetta, South African singer Yvonne Chaka Chaka, and director Spike Lee, to launch MASSIVEGOOD, an innovative fundraising movement that will enable travelers to make a "micro-contribution" towards major global health causes every time they buy a plane ticket, reserve a hotel room or rent a car.

Chikungunya: Experimental vaccine successfully tested in monkeys

Imagine a mosquito-borne virus that has already infected millions of people in recent outbreaks in South and Southeast Asia, the islands of the Indian Ocean, Africa and northern Italy. Although seldom fatal, it causes highly painful arthritis-like symptoms that can linger for months or even years. It's capable of adapting to spread through a mosquito species common in much of North America. And no vaccine or treatment exists to protect humans from its effects.

Study indicates climate change plays a role in malaria transmission

Climate change is one reason malaria is on the rise in some parts of the world, new research finds, but other factors such as migration and land-use changes are likely also at play. The research, published in The Quarterly Review of Biology, aims to sort out contradictions that have emerged as scientists try to understand why malaria has been spreading into highland areas of East Africa, Indonesia, Afghanistan and elsewhere.

Cornell researchers find new protein that may help control mosquitoes from spreading diseases

Cornell researchers have found a protein that may lead to a new way to control mosquitoes that spread dengue fever, yellow fever and other diseases when they feed on humans: Prevent them from urinating as they feed on blood.

Surge in volunteers without overall coordination can make devastating situation worse instead of better

A surge in volunteers following a major disaster can overwhelm a response system, and without overall coordination, can actually make a situation worse instead of better. The outpouring of medical volunteers who responded to the devastating earthquake that rocked Haiti in January provides a roadmap for health care providers during future disasters, say the authors of a New England Journal of Medicine "Perspectives" piece that will be published online February 24.

Researchers keep wary eye on emerging tick-borne diseases in Missouri

Stories of environmental damage and their consequences always seem to take place far away and in another country, usually a tropical one with lush rainforests and poison dart frogs.

Campaign to stop sale of electronic mosquito repellents by major airlines begins to bear fruit

A campaign to stop the sale of electronic mosquito repellents by major airlines is beginning to bear fruit with the immediate withdrawal of the products from KLM flights. The issue being that these electronic repellents, sold to airline passengers, many on their way to malaria endemic countries, just don't work.

Flightless mosquitoes could fight dengue, study says

By rendering female Aedes aegypti mosquitoes - the dengue virus vector - unable to fly, scientists say they may be able to slow the spread of the virus which experts believe "affects up to 100 million people a year and threatens over a third of the world's population," the BBC reports. Currently, there is no treatment for dengue nor a vaccine to protect against the virus.

World Vision receives $19M grant from USAID to help families and communities in Haiti

International relief and development agency World Vision has been awarded a $19 million grant from the U.S. Agency for International Development to help families and communities in Haiti affected by the devastating January 12 earthquake in Port-au-Prince.

UCI researchers create new breed of flightless mosquitoes for dengue control

UCI researchers and colleagues from Oxitec Ltd. and the University of Oxford created the new breed. Flightless females are expected to die quickly in the wild, curtailing the number of mosquitoes and reducing - or even eliminating - dengue transmission. Males of the strain can fly but do not bite or convey disease.
