Dự phòng bằng thuốc

Dự phòng sau phơi nhiễm (PEP) với thuốc kháng virus sau khi phơi nhiễm được ghi nhận có thể làm giảm nguy cơ nhiễm bệnh. Trong tương lai, dự phòng sau phơi nhiễm SARS-CoV-2- có thể được sử dụng để làm giảm sự phát tán virus trong các trường hợp nghi ngờ và như là một phương pháp điều trị dự phòng cho người tiếp xúc.
