A Major Problem in Controlling COVID-19: Increasing Transmission to Healthcare Workers
Abstract
Objective: Little is known about the specific risk factors for healthcare-associated SARS-CoV-2 transmission. The present study evaluated the incidence of risky contact and infection over time and response to hydroxychloroquine prophylaxis in health workers in our hospital fighting COVID-19.
Methods: The first case of COVID-19 in our hospital was detected on March 17, 2020 and was traced to travel abroad. Our analysis included a total of 257 health workers (156 nurses, 84 cleaning staff, 15 physicians, and 2 medical secretaries) who had risky contact with COVID-19 patients between March 23 and May 1, 2020.
Results: In terms of professional groups, the largest proportion of risky contacts was among nurses in weeks 1–2 (n=69) and cleaning staff in weeks 2–4 (n=41), whereas most exposure among physicians occured after week 4 (n=14). Hydroxychloroquine prophylaxis was given to 38 workers who had high-risk contact and negative initial real-time PCR test result. Of these, the 35 workers who completed the treatment still had negative PCR results on day 7, while the 3 workers who did not complete hydroxychloroquine prophylaxis developed symptoms on day 3 and had positive PCR.
Conclusion: If health workers with high-risk contact have negative SARS-CoV-2 real-time PCR results, the use of prophylactic hydroxychloroquine seems effective in keeping the most important soldiers in this war healthy and ready for duty.
