Dengue Fever News and Research

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.

New evolutionary analysis provides insights into how Zika virus spreads between populations

In a study published in Pathogens and Global Health, researchers have modelled the evolutionary development and diversity of the Zika virus to better understand how infection spreads between populations and how the virus reacts with the immune system.

Scientists solve structure of BinAB toxin that kills larvae of certain type of mosquitoes

Could we get rid of mosquitoes without polluting the environment? Yes, we can! The BinAB toxin, produced in crystal form by a bacterium, specifically kills the larvae of Culex and Anopheles mosquitoes, but it is inactive on tiger mosquitoes (or Aedes), the vectors for dengue fever and chikungunya.

Research uncovers new clues to combat dengue and Zika virus

Structural biology research conducted at the U.S. Department of Energy's SLAC National Accelerator Laboratory has uncovered how small insecticidal protein crystals that are naturally produced by bacteria might be tailored to combat dengue fever and the Zika virus.

Scientists reveal new structural insights on key protein from mosquitoes linked to spread of Zika

As health departments around the U.S. boost efforts to combat Zika, scientists are working on new ways to kill the mosquitoes that carry the virus. One approach involves understanding the molecular mechanisms that keep the bugs alive so we can then undermine them.

Study: Risk of sports fans catching dengue fever during Rio Olympics low

The risk of sports fans catching dengue fever during the Rio Olympics is very low, according to a new study involving mathematicians at the University of Strathclyde.

New odour-baited traps offer effective and safe solution to fight against malaria mosquito

The use of a newly-developed mosquito trap incorporating human odour has resulted in a 70% decline in the population of the most significant malaria mosquito on the Kenyan island of Rusinga.

Scientists modeling new control mechanism to combat Zika-infecting mosquitoes

The images are heartbreaking: thousands of infants born with small, misshapen heads, the result of a rare neurological disorder, called microcephaly, which can cause a myriad of intellectual and developmental disabilities. The culprit? Zika, a mosquito-borne virus that has swept through many parts of South America and more recently surfaced in Florida.

Novel crowdsourced disease surveillance tool may help fight against dengue

Brought to you by Break Dengue, Dengue Track is a novel approach to disease mapping which could also be used to tracking Zika virus or Malaria.

OVC research may help improve cancer treatment

Cancer treatment in people could be transformed thanks to a study on treating cancer in animals led by researchers from the Ontario Veterinary College at the University of Guelph.

Scientists use machine learning to interpret mosquito genome

Scientists are using machine learning to identify important sequences of DNA within the mosquito genome that regulate how the insect's cells develop and behave.

Telephone-based disease surveillance system can forecast dengue fever outbreaks

A team of scientists has developed a system that can forecast the outbreak of dengue fever by simply analyzing the calling behavior of citizens to a public-health hotline.

Pre-existing dengue antibodies can intensify Zika virus infection

Previous exposure to the dengue virus may increase the potency of Zika infection, according to research from Imperial College London.

Tackling Zika: are insect repellents the answer? An interview with Bruno Jactel

The repellents that are used today are mostly based on what we call chemical pesticides. These products are used to repel mosquitoes as well as ticks. They are very broadly used, but there are different issues surrounding their use.

Warming temperatures may increase risk for dengue outbreaks in Europe

Increasing temperatures will enlarge Europe's seasonal window for the potential spread of mosquito-borne viral disease, expanding the geographic areas at risk for a dengue epidemic to include much of Europe. The findings by researchers at Umea University in Sweden are published in the journal EBioMedicine.

Research describes first new mouse model for Zika infection in decades

Efforts to combat the rapid spread of Zika virus got a boost this week as researchers at the University of Texas Medical Branch, Galveston (UTMB) announced the first peer-reviewed publication of a mouse model for Zika infection reported in decades.

Biological change in mosquito mating could be used to fight mosquito-borne diseases

Genetic cues from male Aedes aegypti mosquitoes passed on during sex affect which genes are turned on or off in a females' reproductive tract post-mating, including genes related to blood feeding, egg development and immune defense, according to new Cornell research.
