Then, if you no longer have symptoms, wear a mask around others for the next five days. All rights reserved. Those are the patients that are more likely to go to the ICU. Probiotic supplements can be used as one part of an immune-boosting protocol to help reduce the likelihood of coronavirus infection. While scientists know that Omicron is transmitted easier than previous variants, its not known for certain whether its longer persistence on surfaces is the underlying cause of more infections. By mild I mean mostly sore throat. Here, we take a look at some of the most common symptoms associated with the variant for the fully vaccinated - and two early warning signs you might have it.
