Can bacteria stop the spread of dengue and Zika?

Mosquitoes kill an estimated 700 000 people a year by transmitting viruses that cause diseases like chikungunya, dengue and Zika. With the help of WHO, researchers have discovered that mosquitoes artificially infected with a bacterium called Wolbachia do not transmit these diseases as easily. Wolbachia bacteria exist naturally, and it may be possible to create populations of mosquitoes that cannot transmit deadly viruses by infecting them with the bacteria.

Mapping social science research for Zika virus response

Social science research is an essential part of effective risk communication and community engagement for responding effectively to the Zika outbreak. This interactive map allows you to gain overview of such research to input into the response.

Knowledge Attitudes and Practice (KAP) surveys and other social science research allows responders to rapidly obtain valuable and insightful information in order to tailor interventions to better address people's needs at community level.
