A total of 28 cases of hepatitis A infection have been reported over the last few months in Norway, where this disease is said to be rare, the Norwegian news Agency NTB reported Saturday, quoting public health officials.
In almost half of the cases, the patients were found to have been infected with hepatitis A virus while travelling abroad.
The remaining half got infected in Norway, which was described as a rare occurrence.
Last year there was an outbreak of hepatitis A in the Nordic countries, which was believed to be most likely caused by eating imported frozen berries.
Norwegian health authorities suspect the new outbreak in Norway is also caused by eating contaminated food.
