Description
The impact of COVID-19 infection on workers’ work function persists even after the acute
phase of the infection. We studied this phenomenon in Japanese workers.
Methods: We conducted a one-year prospective cohort study online, starting with a baseline survey in
December 2020. We tracked workers without baseline work functioning impairment and incorporated
data from 14,421 eligible individuals into the analysis. We estimated the incidence rate ratio for new
onset of work functioning impairment due to COVID-19 infection during follow-up, using mixed-effects
Poisson regression analysis with robust variance.
Results: Participants reporting infection between January and December 2021 showed a significantly
higher incidence of new work functioning impairment (adjusted incidence rate ratio: 2.18, 95% confidence interval: 1.75e2.71, p < 0.001). The formality of the recuperation environment correlated with a
higher risk of work functioning deterioration in infected individuals (p for trend <0.001).
Conclusion: COVID-19-infected workers may continue to experience work difficulties due to persistent,
post-acute infection symptoms. Companies and society must urgently provide rehabilitation and social
support for people with persistent symptoms, recognizing that COVID-19 is not just a transient acute
infection.
