Tổng Giám đốc Tổ chức Y tế Thế giới (WHO) Tedros Adhanom Ghebreyesus ngày 2/12 cảnh báo hiện nay có hơn 500 dòng phụ của biến thể Omicron , vốn có khả năng lây truyền cao, đang lưu hành. Tất cả các dòng phụ này có thể dễ dàng vượt qua hệ miễn dịch, dù chúng có xu hướng ít gây ra tình trạng bệnh nghiêm trọng hơn so với các dòng phụ trước đó.
