We NEED to work with China, given its history of being the source for H2N2 (1957)...H3N2 (1968)...H5N1 (1997)...SARS-CoV-1 (2003)...Bird Flu (2006)...Swine Flu (2009)...Porcine Pestivirus (2013)...and most recently, SARS-CoV-2 (2019)...it would be medical malpractice for U.S. virologists to not engage with Chinese counterparts (many of whom truly seek to help protect their own citizens)...
