Mỹ: CDC thay đổi chính sách xét nghiệm người phơi nhiễm COVID-19

(TTXVN/Vietnam+) 08:36 27/08/2020

Trung tâm kiểm soát và ngăn ngừa dịch bệnh Mỹ (CDC) đã khuyến nghị những người phơi nhiễm với COVID-19 nhưng không phát triệu chứng có thể không cần xét nghiệm virus SARS-CoV-2. Sự đảo ngược chính sách này của CDC vấp phải sự phản đối của nhiều quan chức và chuyên gia y tế Mỹ.
