Amid a record increase in Covid-19 infections in China, the Centers for Disease Control and Prevention announced that the US would require a negative Covid-19 test from all travellers arriving in the country from China as well as those from Hong Kong and Macau, reported ABC News.

"CDC is announcing this step to slow the spread of Covid-19 in the United States during the surge in Covid-19 cases in the People's Republic of China given the lack of adequate and transparent epidemiological and viral genomic sequence data being reported from the PRC," the CDC said in a statement.
