The person arrived at Danderyd Hospital by ambulance on August 2 and was isolated and sampling confirmed measles. The assessment at the present time is that there is no connection to previous measles cases in the county.

When measles are detected in a person in Sweden, a contact trace is made when the contacts that the sick person has mapped. Those exposed to infection are offered treatment that may involve preventive vaccination or immunoglobulin if necessary.

Measles is a highly contagious disease. Vaccination against measles was introduced in Sweden in the early 1970s, with a general recommendation from 1976. Most Swedes are vaccinated, which makes the disease unusual in Sweden.

Sweden reported 32 cases of measles since the beginning of 2018 as of 3 August 2018.
