I actually know something about this topic (or, at least what the CDC has been saying).

March 28 (via Wayback Machine): 

Can someone spread the virus without being sick?

• People are thought to be most contagious when they are most symptomatic (the sickest).
  
• Some spread might be possible before people show symptoms; there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.

April 2 (via Wayback Machine): 

"There are reports of asymptomatic infections (detection of virus with no development of symptoms) and pre-symptomatic infections (detection of virus prior to development of symptoms) with SARS-CoV-2, but their role in transmission is not yet known."

April 3: 

"Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms."

How would you grade the CDC's communication on this issue? I'm very interested in the responses here, if you have an opinion.
