And the one preventative method you should carry out to avoid catching the virus, according to Dr Jonathan Hayes, is to practice good hygiene.
A GP and clinical chair at Bristol, North Somerset and South Gloucestershire (BNSSG) CCG, Dr Hayes told SomersetLive: “One of the best ways to protect against norovirus is by practicing good hygiene. This includes thorough hand washing with soap and warm water after using the toilet and before eating or preparing foods.
“Most people will make a full recovery within a couple of days but it is important to drink plenty of fluids during that time to prevent dehydration especially in the very young, elderly or those with weakened immunity.
“Also, if you are experiencing symptoms of norovirus please don’t visit hospitals, GP surgeries or care homes. The impact can be huge if you spread norovirus – not just on vulnerable patients who are already unwell but on the availability of beds for other people.”
