Mobile phone records may predict epidemics of mosquito-borne dengue virus

EurekAlert 7 September 2015

A new study led by researchers at Harvard T.H. Chan School of Public Health finds that mobile phone records can be used to predict the geographical spread and timing of dengue epidemics. More people around the world are becoming vulnerable to this deadly virus as climate change expands the range of the mosquito that transmits dengue and infected travelers spread the disease across borders. Utilizing the largest data set of mobile phone records ever analyzed to estimate human mobility, the researchers developed an innovative model that can predict epidemics and provide critical early warning to policy makers.

The study appears online September 7, 2015 in PNAS.

A new understanding of dengue virus

EurekAlert 18 September 2015

A new study is reshaping how scientists look at and understand a deadly virus.

An international consortium of scientists, including researchers from the University of Texas Medical Branch at Galveston, worked to map out the antigenic differences in various strains of dengue virus.

Previously, scientists have described four distinct antigenic variants or serotypes. But in a paper published Friday in Science, researchers reported that while the viruses clustered around the four genetically distinct types, antigenically, or the way a body’s immune system recognizes and responds to the virus, there was overlap among the four dengue types not previously described.

Crime-scene technology adapted for mosquitoes to predict Ross River Virus outbreaks

Sydney Morning Herald 20 September 2015

Cutting-edge technology developed for investigating crime scenes is now being adapted for mosquitoes, in a bid to contain the health risks posed by those carrying viruses.

Last summer was the worst on record for Ross River virus outbreaks, mostly in northern NSW and Queensland, and it took health authorities by surprise.

NSW Health Pathology mosquito researcher Cameron Webb is collaborating with interstate colleagues on a process of barcoding the DNA of mosquitoes. Their goal is to identify which species are most likely to cause disease.

Lyme disease: Experts and sufferers face-off to debate existence of tick-borne condition in Sydney
