Countries with high occurrence of tuberculosis
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, and 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.
Countries with high occurrence are based on estimates from the World Health Organization (WHO) based on resistance evaluation and incidence in Norway. The list was last updated in December 2016.
Since February 2013, countries with an incidence of tuberculosis of 40 or more cases per 100,000 inhabitants per year, or countries with a high incidence of multi-drug resistant (MDR) tuberculosis, are considered to have a high tuberculosis occurrence.
Since March 2017, there is a distinction between high and very high occurrence of tuberculosis. Occurrence of over 200 cases per 100,000 inhabitants is considered to be very high. Afghanistan and Eritrea are included in this group because of high incidence in Norway. The reason for the change is that the test for latent tuberculosis (IGRA) among young adults is being limited to only include new arrivals from countries with high occurrence.
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 the BCG-vaksine.
- All refugees and asylum seekers, even if they come from countries that are not on the list of high occurrence countries.
