The US is planning to relax Covid-19 testing restrictions for travelers from China on Friday, following a surge in cases and lack of transparency from Chinese officials. The Centers for Disease Control and Prevention had previously announced a requirement for travelers to prove they had tested negative for the virus before flying to the US from China, Hong Kong, and Macau. This decision is part of an effort to protect US citizens from the spread of the virus, though it is unclear if the US will continue to require negative tests in the future.
