The knowledge that the virus  caused human to human transmission and that it spreads to wide parts of the population very quickly were critical pieces of information that remained with Chinese epidemiologists, doctors and medical researchers, and were suppressed by local authorites in Wuhan. 

Yet China's version of the U.S. CDC, China's Centre of Disease Control and Prevention, modeled on the U.S. control efforts worked effectively to identify the problem. Virologist Gao Fu, heads China's CDC. This report in Germany's Der Spiegel says Mr. Fu made it a habit to scan China's internet before bedtime for any signs of possible disease outbreaks. On the night of December 30 he came across rumors of an internal memo from the Wuhan Health Commission of an outbreak of a vaguely worded lung disease. When he called the Wuhan health authority he found their answers to be evasive which alarmed him. The next morning December 31 Mr. Fu sent the first of three teams to Wuhan which is how China was able to identify the problem, in the sense that Chinese authorites in Beijing were to rely on Dr Gao Fu to overcome the problem of Wuhan provincial authorites. He informed the World Health Organization Beijing office on that day. The Der Spiegel report says "shortly afterward," the Seattle Times in its report says this was about New Years Day 2020- Mr Fu made a call to Dr. Redfield, head of the U.S. Centre for Disease Control, who was on vacation. Redfield is deeply disturbed on hearing this from Fu and they have conversations over the next few days to the point that Dr. Gao Fu is in tears about what has happened. On January 1 Taiwanese public health authorites shared the information with WHO that the cornonavirus was a human to human transmission, would the Taiwanese authorites not have shared it with the U.S. the same week during calls from the U.S. CDC or other public health authorites alarmed about the situation. (The WHO was proving useless by Jan 14 when it contradicted Taiwan's more reliable assessment  on Jan 14 going by the letter from president Trump to WHO). On January 6 a few days later Dr Redfield and Dr. Azar head of Health and Human Services ask China for permission to send a team of CDC U.S. experts to China. This is cited in the U.S. letter to the World Health organization- the lack of human to human transmission information being given to the U.S. officially early by China. A risk that could have been a topic of conversation between the U.S. and China heads of CDC. That letter from president Trump also points out that the team of experts the U.S. planned to send was not accepted by China till Feb 16, one and half months after that series of conversations between Dr. Gao Fu of China CDC and Dr. Redfield of U.S. CDC in an alert message.  In effect removing one of the key defences for the U.S. and Europe in making their own defensive actions and plans, laying the basis of the worldwide coronavirus pandemic affecting millions of people.

Dr Redfield is a AIDS researcher at the University of Maryland who spent most of his life trying to control spread of HIV and was appointed by president Trump to head CDC agency in 2018. He set a goal of eliminating AIDS by 2030 and is more comfortable with aids patients and research than the bureaucratic nature of agencies- CDC has about 11,000 employees.

Once it was clear that a team of U.S. experts was not given permission to make its own assessment in Wuhan in the few days after January 6 offer to sent the team to China by Redfield of U.S. CDC and Dr. Azar, would it have alerted the U.S. that something was seriously heading the wrong way for a epidemic risk.

That letter of president Trump cites how the head of WHO during the first SARS crisis in 2003, Dr. Harlem Brundtland acted when she faced China's lack of cooperation during that crisis by saying openly that this was a danger to world public health and millions. Could CDC in the U.S. and the other connected health authorites have taken the responsibility and filled Dr Brundtland's role in this crisis, that the WHO failed to perform?
