"If you had an exposure, you're vaccinated and boosted, I don't think that there is any need to be testing, frankly, past about seven days," she said.

Note that the use of fever-reducing medication includes the usual medications, like ibuprofen and acetaminophen, but it also includes any drugs (like over-the-counter cold and flu medicine) that contain those ingredients, Volk says. Scientists can determine that by taking samples from someone who's been infected and trying to grow the virus in a lab what's known as a viral culture. If its challenging to figure out what all those guidelines mean for your specific situation, take a look at the CDCs new quarantine and isolation calculator tool. Another possibility is that people exposed to large doses of the virus might take longer to clear it from their systems, said Aubree Gordon, an infectious disease epidemiologist at the University of Michigan School of Public Health.
