Doctors at Epsom, Sutton and St Helier hospitals are encouraging people to prepare for the return of the 'winter vomiting' bug, norovirus.
The seasonal virus is very infectious and outbreaks often occur in the community, particularly in schools and offices.
Dr Sharon Chambers is a consultant microbiologist and the lead doctor responsible for the control and prevention of infections at the Trust. She said: "The symptoms of a norovirus usually start between 24 - 48 hours after the initial infection, although they can start after as little as 12 hours.
"The first symptom is usually a sudden onset of nausea, which is followed by projectile vomiting and watery diarrhoea. Some people may also have a mild fever, headaches, stomach cramps, or aching limbs.”
Although Epsom and St Helier University Hospitals NHS Trust has yet to see cases of norovirus in its hospitals this year, the virus can easily be brought onto wards by friends and families visiting their loved ones.
Dr Chambers added: "We are starting to see the first reports of norovirus in the community and the weather has certainly turned colder, so we're encouraging local people to take precautions.
"There is no particular treatment for norovirus so the public can help limit the spread by staying away from hospitals and offices if they are unwell, as well as keeping poorly children off school so that they don't spread the illness.
"Because norovirus spreads so easily, those with diarrhoea and vomiting should remain at home until 48 hours after symptoms have stopped. Personal hygiene must also be good so please make sure you wash your hands thoroughly with soap and water before eating and after going to the toilet."
People who have the norovirus can expect the symptoms to go away within one to three days. If they are still feeling ill after this time, they should contact their GP or call NHS Direct on 0845 46 47 for advice.
Norovirus infections can occur at any age because immunity is not long lasting.
