COVID-19 respiratory illness causes only mild or moderate symptoms such as fever and cough in most people, with severe cases more likely in the elderly and those with existing health problems.

Earlier Wednesday, the German government said it had arranged in coordination with state officials to increase hospital capacities, especially for patients requiring intensive care. The government also directed hospitals to check if discarded beds and medical devices could be put back into service, saying experts were predicting the number of cases to rise quickly in coming weeks.
