According to the UK Health Security Agency (UKHSA), cases of norovirus are 70% higher than they usually are around this time. This is calculated as a five season average, excluding 2020 and 2021.
Norovirus is often referred to as the “winter vomiting bug” but it can strike at any time of year. It’s often something that people recover from in a few days but symptoms of the bug include vomiting and diarrhoea.
It can spread very easily through workplaces, schools and communities and while it doesn’t tend to have long-lasting effects, it can be harmful to children and the elderly.
What to do if you get norovirus
So, according to the UKHSA, the virus is easily transmitted through contact with people with the infection and any surfaces or objects that have ben contaminated. There is an incubation period of 12-48 hours which is the time between catching the virus and developing symptoms.
To avoid catching or spreading norovirus, practice good hand hygiene by washing your hands frequently and thoroughly with warm soapy water. This is most important following an episode of illness, after using the toilet, before eating or preparing food as well as clearing up diarrhoea. Also note that hand sanitisers aren’t effective against this and you will need to wash your hands thoroughly.
Finally, stay at home. Don’t return to the workplace or send children back to school until 48 hours after symptoms have stopped.
