[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]This latest COVID made me so sick, but it is also lingering on a rapid test well past the 10 days for both me and my friend.

Seems like you may be infectious for much longer. I am masking but with the latest guidance people probably would not even know. [/quote]

I thought we were already well aware that rapid tests did not provide an indication of infectiosness.  Like, we've known that for years now.  [/quote]

I think you might be thinking about PCR tests. Rapid tests may miss COVID-19, particularly before or just after the onset of symptoms, so a single test is not necessarily reliable in excluding transmissible COVID-19. However, a positive rapid test is considered to be evidence of infectiousness. [/quote]

I think it's a good indication in the first few days of symptoms, but after something like 5 days, a positive antigen isn't a good indication of infectiousness.  The OP is talking about testing for 10 days (or more?) with the implication being to isolate (or something) based on that.[/quote]

+1 I looked at studies on this when I was testing positive for 10+ days and later on when DD was told she could go back to daycare after 5 days. I felt really nervous about sending her back while still testing positive. But what I found are studies showing transmission by and large was not occurring after 5 days - it happens pre symptoms and in the next 2-3 days after symptoms start. Some individuals with compromised immune systems and/or severe COVID may transmit for longer.

Some studies conflate a positive antigen test with infectiousness, but some studies suck. There is a lot of bad science out there. Most people with common sense understand that if the risk of transmission is so minimal (which it is after 5 days) there really is no need to worry.[/quote]
