Norovirus spreads very easily in public places such as hospitals, nursing homes and schools. You can catch it if small particles of vomit or stools poo from an infected person get into your mouth through: close contact with someone with norovirus who may breathe out small particles of the virus that you then inhale touching contaminated surfaces or objects, as the virus can survive outside the body for several days eating contaminated food, which can happen if an infected person doesn't wash their hands before preparing or handling food Norovirus is most infectious from the start of symptoms until 48 hours after all symptoms have stopped.
Preventing norovirus It's not always possible to avoid getting norovirus, but following the advice below can help stop the virus spreading. You should: stay off work or school until at least 48 hours after the norovirus symptoms have stopped avoid visiting anyone in hospital during this time wash your hands frequently and thoroughly with soap and water particularly after using the toilet and before preparing or handling food be aware alcohol-based hand gels don't kill the virus Maintain basic hygiene and cleaning to help stop the spread of norovirus by: disinfecting any surfaces or objects that could be contaminated, using a bleach-based household cleaner.
There's no treatment for norovirus, so you have to let it run its course. You can also: take paracetamol for any fever or aches and pains get plenty of rest use special rehydration drinks, available from community pharmacies if you have signs of dehydration , such as a dry mouth or dark urine If you feel like eating, try plain foods, such as soup, rice, pasta and bread.
When to get medical advice You don't normally need to see your GP if you think you or your child has norovirus, as there's no specific treatment for it. Urgent advice: Speak to your GP or phone if:.

Updates , new cases and new deaths in the United Kingdom. Reported cases are sometimes removed if subsequent tests are negative.
This happens when cases identified through a positive rapid lateral flow test are followed by polymerase chain reaction PCR tests within 3 days that are all negative. These cases are removed daily from 21 May Because of this, the number of newly-reported cases may not be the same as the difference between the total number of reported cases from one day to the next. Some emerging variants are worrying, but many are inconsequential.
The difficult job is spotting, tracking and managing the ones that could matter. The UK is a front-runner in carrying out these vital lab analyses, having completed more than a million tests so far. The first step is to pick up new mutants worth watching, such as this new offshoot - AY. Next, if there is a strong suggestion that the genetic changes might make the virus more contagious, it is classified as a variant under investigation and more checks are done.
If it becomes clearer that it could be more transmissible and escape some of the built up immunity from past infections or vaccines, or potentially cause more serious disease, it is moved into the variant of concern category. That's the one Delta belongs to. At this stage, experts don't think AY. So we are talking about something quite subtle here and that is currently under investigation.
It's excellent that we have the facilities and infrastructure in place to see anything that might be a bit suspicious.
It might be slightly, subtly more transmissible but it is not something absolutely disastrous like we saw previously. The Prime Minister's official spokesman said: "It's something we're keeping a very close eye on.
