People from countries with a high occurrence of tuberculosis are obliged to undergo tuberculosis testing if they intend to stay more than three months in Norway. Their children will be offered BCG vaccination. The Norwegian Institute of Public Health maintains the list over which countries are considered to be high occurrence countries. From March 2017, there is a distinction between high and very high occurrence to help target screening for latent tuberculosis.
What does "high occurrence" mean?
According to the Norwegian regulations for tuberculosis control, the Norwegian Institute of Public Health must state which countries have a high occurrence of tuberculosis.
The list of countries with high occurrence is based on estimates from the World Health Organization (WHO) and data on incidence in Norway. The list was last last updated in December 2018.
In march 2017, a distinction between "high" and "very high" occurrence of tuberculosis was introduced. All immigrants from countries classified as "high" occurrence should be tested for tuberculosis disease, while testing for latent tuberculosis is limited to young adults newly arrived from countries with "very high" occurrence.
The cut-offs are set so that occurrence of over 40 cases per 100 000 inhabitants is considered to be "high", while over 200 cases per 100,000 inhabitants is considered to be "very high". Two other countries (Eritrea and Afghanistan) are included in the latter group because of high incidence in Norway.
Obligatory tuberculosis testing
These people are required to undergo tuberculosis testing:
- People arriving from countries with high occurrence if they intend to stay for more than three months in Norway. Children will be offered BCG vaccination.
- All refugees and asylum seekers, even if they come from countries that are not on the list of high occurrence countries.
