Winter sickness continues this season – Public Health Agency

Searches on the 1177.se website and statistics from the country’s laboratories show that the spread of winter sickness has gained momentum in the community, and that the season has now begun. Cases of the disease can occur throughout the year, but a significant increase in winter sickness is usually observed between November and April.

– It cannot be said to what extent the spread will be. Last year we saw a prolonged outbreak of infection, when relatively many cases were reported late in the season. At the beginning of the COVID-19 pandemic, there were very few cases of winter sickness, but recent seasons have been more active than before the pandemic. It remains to be seen whether this trend will continue, says Else Ydering, an epidemiologist at the Norwegian Public Health Agency.

Winter sickness is highly contagious

The virus that causes winter sickness is highly contagious and can spread between people and from objects in the environment. Good hand hygiene is one of the most important measures to protect against infection, both in healthcare and in the rest of society. By following good hygiene procedures, the risk of infection among hospitalized patients can be reduced.

– Elsie Yedring says: – Your risk of getting sick and spreading the infection to others is reduced when you wash your hands with soap and water.

People with winter vomiting sickness or who suspect infection, for example after caring for a sick person, should be extra careful about hand hygiene and should not handle food that others will eat. People with symptoms should limit physical contact with others as much as possible.

It is also important that there is an opportunity to wash hands in places where many people gather, for example in schools, nurseries and other public environments to prevent the spread of infection. Paper towels, not cloth towels, should be used in workplaces, schools and nurseries.

Most types of hand sanitizers do not have sufficient effect against the winter vomiting virus. Often there are large amounts of viruses that need to be washed out. Therefore, thorough cleaning with soap and water is recommended.
