RSS

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.

Researchers analyze people’s initial immune response to dengue fever

Researchers have come one step closer to understanding how our immune system responds to acute dengue fever, a disease that has affected hundreds of thousands of people in Southeast Asia this summer alone.

Thymol antimicrobial in corn starch can help fight mosquito-borne diseases

The Aedes aegypti mosquito is the major vector for many urban arboviruses, which can cause serious conditions such as dengue fever, Zika virus, Chikungunya, and yellow fever. Now, researchers have developed a cheap but effective larvicide using cornstarch.

Researchers find mechanism behind susceptibility to viral infections

A team of researchers from the SingHealth Duke-NUS Academic Medicine Centre's Viral Research and Experimental Medicine Centre found that immune cells undergoing stress and an altered metabolism are the reasons why some individuals become sick from viral infections while others do not, when exposed to the same virus.

Higher levels of doublets in flow cytometry indicate tuberculosis or dengue fever

Sorting through individual immune cells is a handy way to see how the body responds to disease. For years, researchers around the world have used a technique called flow cytometry to separate different types of immune cells, such as T cells, B cells and monocytes.

FDA approves first vaccine for prevention of dengue disease in endemic regions

The U.S. Food and Drug Administration announced today the approval of Dengvaxia, the first vaccine approved for the prevention of dengue disease caused by all dengue virus serotypes (1, 2, 3 and 4) in people ages 9 through 16 who have laboratory-confirmed previous dengue infection and who live in endemic areas.

Previous dengue infection could protect against Zika-associated damage

The Zika virus outbreak in Latin America has affected over 60 million people up to now. The infection can have potentially fatal consequences for pregnant women and their unborn children: many children have subsequently been born with malformations of the head, or so-called microcephaly.

Egg yolk precursor protein plays key role in regulating mosquitos’ attraction to humans

Feeding mosquitoes sugar makes them less attracted to humans, a response that is regulated by the protein vitellogenin, according to a study publishing May 9 in the open-access journal PLOS Biology by Jessica Dittmer, Paolo Gabrieli and colleagues at the Università degli Studi di Pavia in Italy.

Innovative model identifies primate species with potential to transmit Zika in the Americas

In the Americas, primate species likely to harbor Zika - and potentially transmit the virus - are common, abundant, and often live near people. So reports a new study published today in Epidemics. Findings are based on an innovative model developed by a collaborative team of researchers from Cary Institute of Ecosystem Studies and IBM Research through its Science for Social Good initiative.
