There are P.C.R. tests for stool samples available, Dr. Krueger said, but doctors use those tests only in rare instances.
How do you treat norovirus?
There is no treatment for norovirus, Dr. Lighter said; you just need a few days to let the infection run its course. But there are ways to manage your symptoms.
Above all, it’s crucial to get enough fluids, as the liquid you lose from vomiting and having diarrhea can cause dehydration — which, in turn, can lead to serious complications and potentially hospitalization. Water can help keep you hydrated, but you may want to reach for an electrolyte drink, especially if you are vomiting, Dr. Sabella said, to avoid an electrolyte imbalance.
How do you know if you’re adequately hydrated? With babies, Dr. Sabella said, look for frequent, wet diapers. Children and adults should be urinating regularly and their pee should be a light, clear yellow, Dr. Krueger said. Keep a close eye on infants and older people, she added. If they are acting lethargic, it may be a sign that they are extremely dehydrated and that you should seek medical attention.
Don’t force yourself to eat when you’re still throwing up frequently, Dr. Sabella said, but once the vomiting subsides, opt for bland foods like bananas and toast until you feel better.
Can you get norovirus multiple times?
Yes. (Sorry.) There are numerous strains of norovirus, so it’s possible to get infected more than once. You will probably have some short-term protection from the virus after you recover, Dr. Sabella said, but because norovirus moves through the body so quickly, your immune system doesn’t have time to form lasting defenses against it. Fortunately, though, subsequent bouts of the virus tend to be less severe if they occur in the same season, Dr. Sabella said.
Yikes. How can I avoid getting norovirus?
The most important thing you can do is wash your hands frequently with warm water and soap, Dr. Sabella said. Don’t use hand sanitizer or alcohol sprays, like those from Purell, in lieu of washing your hands because they are not as effective as soap and water, Dr. Lighter added.
