Facts about Noroviruses

Burden: The disease burden of Norovirus in Europe is 4 DALY per 100 000 people each year (equals to 33 000 DALY each year). DALY: (Disability Adjusted Life years) is a measure for the total health burden where one DALY can be thought of as one year of “healthy” life lost. Cases: More than 14 mill European citizens suffer from Norovirus infections each year.Deaths: Norovirus causes more than 400 deaths each year. Sources: The most common sources for Norovirus are crustaceans, shellfish and bivalve molluscs.

The estimated total health burden, DALY is four by 100.000. This reflects that a lot of people get ill from the virus, but very many recover after a shorter period of illness.
