And, in the U.S., COVID-19 cases are climbing just as fast. Researchers determine how long someone can be infectious by taking samples from someone who has tested positive for the virus, and trying to grow an infectious virus from it. With PCR tests, which look for the virus's genetic material, people may test positive for even longer, Dr. Alberto Paniz-Mondolfi, associate professor at the Icahn School of Medicine at Mount Sinai, tells TODAY.com.

But Hay cautions there is considerable variation in the studies because of small sample sizes, differing populations, how the rapid tests are done, the vaccination status of who's being tested and how healthy they are, among other factors.
