Globally,
the number of new COVID-19 cases and deaths has continued to decline since the

During
the week of 18 through 24 April 2022, over 4.5 million cases and over 15 000 deaths

previous week. However, an increase in the number of new weekly cases was
reported from the Regions of the Americas (+9%) and the African Region (+32%),
and the number of new weekly deaths increased in the South-East Asia Region
(+41%), due to a delay in reporting of deaths from India, and in the Africa
Region (+110%).
As

have been reported globally.
