A Dec. 2threat assessment brief from the European Centre for Disease PreventionandControl similarly explains that while none of the few omicron cases so far in Europe have been severe, it would take hundreds of cases to observe patients with complications if the severity is similar to the delta variant and it could be a little while before this becomes more clear. A: There is currently no strong evidence that acetaminophen use during pregnancy causes autism or ADHD in children.

Simultaneous checks for two other parts of the virus still work, though. As weve explained before, testing can help limit the spread, but its still possible for someone to test negative early in the course of an infection, before the amount of virus is sufficient to be detected particularly when using the popular rapid tests that are less sensitive than a PCR test, which can take a few days to get results.

Experts say the limited data are hard to parse, and there are several factors other than a change in disease severity that could explain the observations. The at-home tests are a key part of keeping the virus under control.

This includes highly sensitive polymerase chain reaction, or PCR, tests, which evaluate the presence of viral RNA in a sample, along with rapid tests that check for viral proteins, or antigens. Rapid antigen tests are not as accurate as PCRs, which are handled in a lab, but they have several advantages: they are faster, cheaper, can be done at home and have proven sufficiently sensitive when the person has a higher viral load and is therefore more contagious (although the spread of the omicron variant is complicating this picture).
