Background: Coronavirus disease (COVID-19) mainly spread through respiratory droplets and close contacts.  Wearing a facemask and other personal protective equipment (PPE) is essential in preventing the spread of COVID-19. However, the use of PPE alone does not provide a sufficient level of protection, and correct use and disposal are required. Hence, this study aimed to assess health professionals' practice regarding proper use of facemask in the perspectives of COVID-19 prevention.

Methods: A web-based online survey was conducted from June 3, 2020, to August 11, 2020, to assess health professionals' practice regarding correct use of facemask. The survey tool was prepared in Google form and distributed to the health professionals through their emails and social media pages. Data were analyzed using STATA version 14. A descriptive result was reported using frequency tables and bar charts. Factors associated with correct use of facemask were assessed using binary logistic regression.

Results: A total of 368 health professionals have participated in this study. All of the participants' work involves direct contact with patients and 98 (26.6%) of them work in direct contact with COVID-19 patients daily. The level of overall correct use of facemask was 10.1% (95% CI: 7.4-13.6). Two hundred fifty-five (69.3%) do not perform hand hygiene before wearing a facemask and 238 (64.7%) do not perform hand hygiene after removing the facemask. Three hundred twenty-three (87.8%) of the study participants reuse disposable facemasks. The odds of practicing correct use of facemask were more than two times higher among health professionals who received training related to personal protective equipment utilization (AOR= 2.2, 95% CI: 1.1-4.5) compared to their counterparts.

Conclusion: This study revealed that health professionals' practice regarding correct use of facemask in the context of COVID-19 prevention is very low. Receiving training related to proper utilization of personal protective equipment was found to favor the correct use of facemask. In this regard, health authorities should provide training to enable the rational and correct use of facemask among healthcare workers.
