I see many posts referring to this virus being contagious during while being asymptotic but infected. Is there any other proper source of this? Our government/health agency is denying asymptotic transmission happens.
May I ask which country?
If the CDC, WHO, and PhD's of Public Health are all saying the same thing, it's probably true.
The people I trust on this have been quite reserved in their statements as is the article you linked to. It still looks like we don't know for sure.
