Underreporting of Work-Related COVID-19 Cases in Norway

Abstract

Background: This register-based study provides a profile of work-related Covid-19 cases reported by physicians to the Norwegian Labor Inspection Authority (NLIA). Methods: All the reports of work-related Covid-19 cases reported by a physician to the NLIAs Registry for Work-Related Diseases (RAS) between February 2020 and February 2022 were included. Descriptive statistics and the incidence rate of reported cases were computed for age, gender, and occupation. Results: Two hundred and seventeen work-related Covid-19 cases were reported to RAS during the study period. Sixty-five percent of the cases were females ( n = 141), and 35 percent ( n = 76) were males. Doctors, nurses, and ambulance personnel yielded higher incidence rates than other healthcare and nonhealthcare occupations. Conclusions: This study indicates that women aged 25–39 and employed in the healthcare sector had the highest reported incidence and number of work-related Covid-19 cases. Physician underreporting of work-related Covid-19 cases is an important finding. Plausibly, underreporting is more substantial for at-risk non-healthcare occupations such as waiters, bartenders, food couriers, and taxi drivers than occupations in healthcare.
