WHO response to Zika virus

12 January 2017 -- WHO looks back on its key activities for the Zika response, as it refocuses priorities for the long-term management of the disease. Support from donors is crucial to continue to invest in research and development to foster a better understanding of Zika virus, and how we can prevent and treat the adverse health outcomes associated with it.

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.


Zika is here to stay and remains a significant public health challenge

18 November 2016 -- Zika virus and associated consequences remain a significant public health challenge requiring intense action, but they no longer represent a Public Health Emergency of International Concern.


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.


Quarterly update of the Strategic Response Plan

26 October 2016 -- The first quarterly update of the Zika Strategic Response Plan (July 2016 to December 2017) includes the latest information on Zika across the globe as well as the resources needed to prepare for and respond to Zika virus and potential neurological complications.

As we continue to learn more about Zika virus, these updates aim to guide coordination and collaboration among WHO and its partners so that countries’ preparedness and response capacities are supported to the fullest extent possible.

Zika Virus Research Agenda

25 October 2016 - Research and evidence are the foundation for sound health policies. The goal of the WHO Zika Virus Research Agenda is to support the generation of evidence needed to strengthen essential public health guidance and actions to prevent and limit the impact of Zika virus and its neurological complications. The agenda identifies critical areas of research where WHO is uniquely placed to implement or coordinate global activities.
