Occupational risk of COVID-19 by country of birth. A register-based study.

BACKGROUND

Occupational exposure has been suggested to contribute to a disproportionate burden of COVID-19 among immigrants. We aim to assess this hypothesis in Norway.

METHODS

In 2729 627 adults born in Norway, Somalia, Pakistan, Iraq, Afghanistan and Turkey, we examined whether persons employed as taxi drivers, bus and tram drivers, child care workers, nurses, personal care workers in health, food service counter attendants, waiters/bartenders, cleaners and shop sale persons had a higher risk of COVID-19, from 1 April 2020 to 2 December 2020, compared with (i) Norwegian-born in the same occupational group and (ii) all others with the same birth country and aged 20-70 years, using logistic regressions.

RESULTS

Within each occupational group, immigrants had a greatly increased odds of COVID-19 when compared with Norwegian-born (odds ratio [OR] ~ 1.66-12.72). However, immigrants working in the selected occupations had the same odds of COVID-19 as person with same birth country not having the same occupation (OR ~ 1). Exceptions were Somalian, Afghani and Iraqi personal care workers in health services who had an increased odds of COVID-19 compared with others from the same country.

CONCLUSION

Occupation is not an important driver of the high rates of COVID-19 among immigrants from Somalia, Pakistan, Iraq, Afghanistan and Turkey.
