Weekly epidemiological update on COVID-19 – 29 March 2022
Between the end of January and early March 2022, there was a consistent decreasing trend in the number of new COVID-19 cases, which was followed by two consecutive weeks of increase in cases. During the week of 21 through 27 March 2022, the number of new cases declined again with a 14% decrease as compared to the previous week. On the other hand, during the same period, the number of new weekly deaths has increased by 43%, driven by changes in the definition of COVID-19 deaths in countries in the Region of the Americas (Chile and the United States of America) and retrospective adjustments reported from India in the South-East Asia Region.

Across the six WHO regions, over 10 million new cases and over 45 000 new deaths were reported. All regions reported decreasing trends in the number of new weekly cases and four regions reported a decreasing trend in new weekly deaths. As of 27 March 2022, over 479 million confirmed cases and over 6 million deaths have been reported globally.

In this edition, we provide updates on the geographic distribution of circulating SARS-CoV-2 variants of concern (VOCs), including information on recombinant variants.
