Infants and the elderly are at risk of becoming seriously ill.
"Especially the youngest children are at risk of becoming seriously ill, and may have difficulty breathing. Children under 1 year of age should not meet people outside the family who have a cough or runny nose," says AnnaSara Carnahan, epidemiologist at the Swedish Public Health Agency, in a press release.
To protect newborns, a free preventive treatment is being offered for the first time. The treatments consist of injections given after birth and protect against serious RS infection for up to six months.
