Trong bối cảnh các ca mắc COVID-19 trên toàn cầu đang tăng trở lại, Tổ chức Y tế Thế giới (WHO) cho biết đang theo dõi chặt chẽ AY.4.2 - một biến thể phụ của chủng Delta, nhằm đánh giá liệu mức độ lây nhiễm của biến thể này có cao hơn so với chủng ban đầu hay không. Biến thể phụ này đã được phát hiện ở ít nhất 42 quốc gia trên thế giới.
