Reading the two official reports from the WHO and the CDC on the SARS-CoV-2 virus and the COVID-19 disease that it causes, I notice the following major discrepancy.
The WHO report on the COVID-19 disease in China released on Feb 25 had this to say about asymptomatic infections with the SARS-CoV-2 virus.
A month later, the CDC report released recently stated the contrary to the above, when studying the passengers on the stricken Diamond Princess cruise ship.
How to explain the discrepancy?
Note that the WHO report was co-authored by China medical experts. The West learned of the virus outbreak in Wuhan back in January 2020. China did not allow the WHO to go in to observe until mid February 2020. I recall being surprised that the WHO published the report quite quickly after being allowed into China. With the WHO having limited amount of time and access to the "battle front", I would think that the WHO had to rely on a lot of data collected and presented by China. Somehow, that was not corroborated by the field observation that CDC made on the passengers on the cruise ships.
I also recall that the US wanted to send along CDC experts with the WHO, but China did not agree to the request.

Asymptomatic infection has been reported, but the majority of the relatively rare cases who are asymptomatic on the date of identification/report went on to develop disease. The proportion of truly asymptomatic infections is unclear but appears to be relatively rare and does not appear to be a major driver of transmission...
A month later, the CDC report released recently stated the contrary to the above, when studying the passengers on the stricken Diamond Princess cruise ship.
Available statistical models of the Diamond Princess outbreak suggest that 17.9% of infected persons never developed symptoms. A high proportion of asymptomatic infections could partially explain the high attack rate among cruise ship passengers and crew...
