The United States (US) is considering sampling wastewater taken from international aircraft to track any emerging new Covid-19 variants as infections surge in China. The US and a number of other countries have said travellers from China will require mandatory negative COVID tests. Cumulative deaths in China since 1 December likely reached 100,000, with infections totalling 18.6m, Airfinity said in a statement on Thursday. Airfinity expects China’s Covid infections to reach their first peak on 13 January with 3.7m cases a day. Japan will require a negative COVID-19 test upon arrival for travellers from China, and Malaysia announced new tracking and surveillance measures.
