Prevalence of SARS-COV-2 Antibodies in Dental Healthcare Providers

Abstract

Background: Occupational hazards and risks are a common public health issue, especially when healthcare workers safety is concerned; they are on high risk of catching infections such like COVID-19. The possibility of cross-infection between dental practitioners and patients is significantly higher due to the close exposure of dental staff to patient oral environment.

Aim: To assess the prevalence of SARS-COV-2 antibodies in dental workers working in the Peshawar Dental College and Hospital, Peshawar.

Study Design: Cross sectional study

Place and Duration of Study: Department of Orthodontics, Peshawar Dental College & Hospital, Peshawar from 1^st January 2020 to 31^st December 2020.

Methodology: One hundred and thirty three dental workers were enrolled. The investigation was run to detect immunoglobulin G and M antibodies against the SARS-CoV-2-2. The aspirated aerosol and air was evacuated and dissipated into the atmosphere.

Results: Mean age was 29.4±1.4 years and males were dominant 74 (55.6%) and male workers found greater with positive antibodies. The prevalence of SARS-CoV-2 antibodies was 33.0%. Proportionately dental assistants (20.5% vs 16.9%) and ancillary staff (20.5% vs 10.1%) had higher prevalence. Sore throat and body aches were more common in positive antibodies cases while travel history was found significantly associated with it (40.9% vs 25.0%, p-value, 0.05).

Conclusion: High frequency of SARS-COV-2 antibodies was found in dental workers showing a high infection rate of COVID-19 in healthcare workers in local settings.
