Epidemics can occur anywhere, at any time.

We publish regular updates, produced by Program for Monitoring Emerging Diseases (ProMED), on outbreaks of emerging infectious diseases to keep you informed on the frequency and impact of our priority diseases.

ProMED is the largest publicly-available system conducting global reporting of infectious diseases outbreaks, with ProMED staff, moderators and team members scanning for, reviewing and posting information relating to global health security from official health reports and media articles.

The below post contains information from health reports, news articles, and academic papers relating to our priority diseases, compiled together by ProMED. Content below may be edited from original ProMED posts for style and length.

These posts provide an overview of disease outbreak activity over the past several weeks. For the latest information relating to outbreaks of infectious diseases, please visit the ProMED website.

From 1-31 Oct 2019, the National IHR Focal Point of Saudi Arabia reported 15 additional cases of Middle East respiratory syndrome (MERS-CoV) infection and 6 associated deaths.

Democratic Republic of Congo

Outbreak Update

As of 3 December 2019, the cumulative number of cases is 3313, of which 3195 are confirmed and 118 are probable. In total, there were 2207 deaths and 1084 people healed. 326 suspected cases are under investigation. The cumulative number of confirmed/probable cases among health workers is 163 (5% of all confirmed/probable cases), including 41 deaths.

To date, 255 716 people have been vaccinated with rVSV-ZEBOV vaccine, produced by Merck, and 1070 have been vaccinated with the second Ebola vaccine, produced by Johnson and Johnson.

Since the beginning of the epidemic, the total number of travelers checked (temperature measurement) at the sanitary control points is 123 008 402.

Over the past couple of weeks, Ebola response activities have been severely disrupted in some areas due to security reasons. This includes a reduction in the volume of reported and investigated alerts and the number of contacts registered and followed. The volume of alerts from health zones affected by insecurity is lower than usual, and this has led to an overall reduction in the average number of alerts reported.

Key global health development

Gavi, the Vaccine Alliance announced that it will create and fund an emergency Ebola vaccine stockpile, part of efforts meant to streamline the response to future outbreaks.

The stockpiling plan was approved by Gavi's board, which met this week in New Delhi, India.

Gavi said it will open a new funding window with an investment of USD 178 million between now and 2025, which will allow low- and middle-income countries to get the vaccine free of charge. The stockpile will include 500 000 doses, the number recommended by the WHO Strategic Advisory Group of Experts (SAGE) on Immunization.
