Probiotic supplements can be used as one part of an immune-boosting protocol to help reduce the likelihood of coronavirus infection. Their effectiveness can vary depending on how you use them and the types of germs.

Whether changes in duration of infection are a result of variant characteristics or the public's vaccination status is unclear. One, from a team at Harvard University, showed that a harmless virus, engineered to display Omicrons spike on its surface, more easily penetrated human cells in a dish; another, out of Hong Kong University, found that Omicron multiplied dozens of times faster than Delta in tissue extracted from the upper airway. People are also getting less sick because their immune system has seen it already, Khabbaza said. Again, the Omicron variant lasted the longest on skin at 21.1 hours.

A truncated incubation makes a virus much, much, much harder to control, Jennifer Nuzzo, an epidemiologist at the Johns Hopkins Center for Health Security, told me. Shorter incubation periods generally lead to more infections happening in less time, because people are becoming more contagious sooner, making onward transmission harder to prevent. Results found that of the 66 guests out of 117 fully vaccinated attendees who tested positive for Omicron and the 15 who were found to have probable cases, over a dozen reported that their symptoms cleared within a matter of days.
