Germany

The figure above relates to the number of COVID-19 patients requiring intensive care and that has risen back to 4,355 as of yesterday with there being just 3,417 (14%) intensive care beds still available across the country.

Given the situation, expect lockdown measures to be extended well beyond 18 April and until the vaccine rollout gathers pace in the weeks/months ahead.
