REUTERS/Tingshu WangBEIJING/WUHAN, Jan 2 (Reuters) - Some people in China's key cities of Beijing, Shanghai and Wuhan braved the cold and a spike in COVID-19 infections to return to regular activity on Monday, confident of a boost to the economy as more recover from infections. But Monday's one new COVID death - flat with the previous day - among China's population of 1.4 billion does not match the experience of other countries after they re-opened. Cumulative deaths in China since Dec. 1 have probably reached 100,000, with infections at 18.6 million, it said. Airfinity expects China's COVID infections to reach their first peak on Jan. 13, with 3.7 million daily infections. China has said it only counts deaths of COVID patients caused by pneumonia and respiratory failure as COVID-related.
