BRASILIA, Dec 9 (Reuters) - The jumps in weekly COVID-19 case counts in the United States and Canada is particularly worrisome as winter approaches, the World Health Organization director for the Americas, Carissa Etienne, said on Wednesday.
Mexico is experiencing a resurgence in cases in the state of Baja California, near the U.S. border, she said in a briefing. Brazil is currently reporting the highest incidence of new cases in South America, and the mounting cases and deaths have put its health system under strain and hospitals are at capacity in some areas, Etienne said.
