Emergencies preparedness, response

Pandemic and epidemic diseases (PED)

Epidemic focus


The interactive timeline provides a rapid 'need to know' spotlight on current infectious disease threats. It is not intended to be an exhaustive list of cases and outbreaks but a focus on reasons for concern about specific infectious diseases currently posing threats to global public health.

Timeline: Yellow fever outbreak 2016

WHO/M. Marrengula

The outbreaks of yellow fever in Angola, Democratic Republic of the Congo and Uganda have placed great demand on the global supply of yellow fever vaccines. The global stockpile of 6 million vaccines for emergency response (normally enough for a year) has already been replenished twice this year.

This timeline shows the demands on the global vaccine supply since early 2016.

Pandemic and Epidemic Diseases (PED)

Emerging and re-emerging epidemic diseases pose an on-going threat to global health security.
The WHO's Twelfth General Programme of Work sets the reduction of "mortality, morbidity and societal disruption resulting from epidemics... through prevention, preparedness, response and recovery activities" as one its five strategic imperatives.

The Department of Pandemic and Epidemic Diseases (PED) develops strategies, initiatives, and mechanisms to address priority emerging and re-emerging epidemic diseases, thereby reducing their impact on affected populations and limiting their international spread.
