Brazil is the most seriously affected country in Latin America. In order to prevent the spread of the epidemic, many Brazilian states have taken social isolation measures. Brazils new health minister, Nelson Taichi, resigned on the 15th after disagreeing with President bosonaro over measures to prevent the epidemic. Previously, former health minister Luis mendetta was sacked in mid April for failing to reach an agreement with bosonaro on epidemic prevention measures. In a month, two health ministers resigned one after another, making it difficult for Brazils epidemic prevention work to be carried out systematically. Experts warned that this would increase the risk of the epidemic out of control in Brazil.
