This extract from a WHO briefing keeps nagging at me .
First, COVID-19 does not transmit as efficiently as influenza, from the data we have so far.
With influenza, people who are infected but not yet sick are major drivers of transmission, which does not appear to be the case for COVID-19.
Evidence from China is that only 1% of reported cases do not have symptoms, and most of those cases develop symptoms within 2 days
I was so pleased to think that CV was less effecient that spreading than influenza . But now I think to myself the above quoted 1% may gloss over a lot of unreported cases .
Guessing the 1% come from contacts of infected people that were tested as a precaution who were tested and then went on to show symptoms and to test positive . But the incubation period can vary so they could have been asymptomatic for more than a few days and shedding the virus .
And surely asymptomatic cariers and those with it mildly have gone unreported .Less than1% of reported cases being asymptomatic and shedding for about 2 days may not prove that CV is less effecient at transmitting than flu .
Or am I reading it all wrong .( Assuming people can make sense of what I'm saying )
