Norway – searches for source of hepatitis A outbreak – food suspected

Food Safety News

Norwegian public health officials are investigating an outbreak of hepatitis A that has affected 10 people.

The Norwegian Institute of Public Health (FHI) reported an investigation has been started with local health services and the Norwegian Food Safety Authority (Mattilsynet) but the suspected source is unknown.

Infection has been detected in 10 people living in several counties. Another two people are suspected of being part of the outbreak.

Samples were taken from April to September and sequencing shows hepatitis A virus (HAV) with an identical sequence of genotype 1A in all of the patients. This suggests they were infected from the same source.

Sick people are between 25 and 80 years old with a median age of 53. Sixty percent are men.

Widely distributed food suspected
Six patients live in Viken, two in Trøndelag and one each in Oslo, Vestfold og Telemark, Innlandet and Troms og Finnmark.
