People who show certain symptoms have been told to stay at home for at least two days
The UK Health Security Agency (UKHSA) has issued a stark warning about a nasty bug causing two grim symptoms and shared NHS advice on how to prevent its spread. In a post on X, formerly known as Twitter, the UKHSA described norovirus as “unpleasant for everyone”.
The alert continues: “If you come down with a case, here is what you can do to reduce the spread.” An accompanying video further explains that anyone suffering from diarrhoea, vomiting, or feeling unwell should stay at home for at least 48 hours after their symptoms have cleared.
Regular hand washing with soap and warm water is advised, along with washing any soiled clothes or bedding at 60 degrees. Other symptoms, according to the UKHSA, may include a fever, headache, and aching arms or legs.
Additional information available on the NHS website explains that diarrhoea and vomiting can spread rapidly and easily.
It advises that you should “stay off school or work until you’ve not been sick or had diarrhoea for at least two days”, and “try to stay at home or avoid contact with other people until you feel better” if you have a high temperature and/or do not feel well enough to carry out your normal activities.
To help stop any bugs spreading, in addition to the advice given above, it’s recommended to clean toilet seats, flush handles, taps, door handles and surfaces daily, and avoid preparing food for others where possible.
Sharing towels, flannels, cutlery or utensils should be avoided, and swimming pools should not be used until at least 48 hours after symptoms have subsided.
