BEIJING/SHANGHAI (Reuters) – Mainland China on Monday reported a drop in its daily tally of new coronavirus cases, reversing four straight days of increases, as the capital, Beijing, ramped up measures to contain the number of infections arriving from abroad. China had 39 new confirmed cases on Sunday, the National Health Commission said, down from 46 a day earlier. Beijing stepped up measures to contain imported infections, diverting all arriving international flights from Monday to other cities, including Shanghai and as far west as Xian, where passengers will undergo virus screening.
