The WHO Health Emergencies Programme is currently monitoring 130 events in the region.

Major issues and challenges include: South Africa recorded the highest number of cases in the past seven days, although with a minimal overall percentage decrease. During the past week, Uganda has become the first country to confirm the presence of the variant first identified in India, which is a potential threat to the East African area. The risk of COVID-19 resurgence remains high in African countries due to poor adherence to public health measures, mass gatherings, and low testing and vaccination rates. The current upsurge in India could also have a negative implication on vaccine availability globally, particularly in Africa. Health worker infections remain of concern as the numbers continue to increase across the region. The situation in Guinea remains stable, with no new confirmed cases for the past 21 days. However, the presence of 19 new suspected cases is of concern, as is the continued presence of a known confirmed case in the community. Alert reporting by the community is poor, with most reported through active case search and there continues to be resistance to safe and dignified burial. The WHO response plan is still only 17% funded, which threatens to derail ongoing response measures. 1 Health Emergency Information and Risk Assessment Health Emergency Information and Risk Assessment Ongoing events 157 Ebola virus disease Democratic Republic of the Congo End of outbreak declaration The Democratic Republic of the Congo on Monday, 3 May 2021, The distribution of Ebola virus disease cases declared the end of the Ebola virus disease (EVD) outbreak that in Democratic Republic of the Congo as of 1 May 2021 was first announced on 7 February 2021 after a woman resident in Masoya health area in Butembo Health Zone, tested positive for EVD.
