Nasty disease-carrying mosquitoes from South-East Asia detected in Brisbane

The Courier Mail Damon Guppy April 16, 2015

EXOTIC mosquitoes with the potential to spread crippling diseases have been found at Brisbane International Airport three times in the past two months, forcing heightened biosecurity measures.
The cargo holds of planes from select South-East Asian countries are being fumigated following the discovery of the Aedes aegypti mozzies, which can carry viruses such as dengue, chikungunya and yellow fever.

Plotting the elimination of dengue

EurekAlert |  April 8, 2015

Dengue is a viral infection spread between humans by Aedes aegypti mosquitoes. Dengue causes flu-like symptoms, including intense headaches and joint pains. Published in the journal Science Translational Medicine, Professor Cameron Simmons, from the Department of Microbiology and Immunology at the University of Melbourne and the Peter Doherty Institute for Infection and Immunity, said that the discovery could lead to improved strategies to reduce the incidence of dengue.  Continue reading…

Is climate change to blame for outbreaks of mosquito-borne disease?

The Conversation Cameron Webb 3 April 2015

The east coast of Australia is currently experiencing one of its worst outbreaks of mosquito-borne disease in years. Mosquitoes have plagued the summer and now there’s a dramatic increase in disease caused by Ross River virus, spread by the bite of mosquitoes.  While a changing climate may contribute to more mosquito-borne disease, it doesn’t guarantee it: human movement around the world is likely to play just as an important a role.
