Abstract
COVID-19 is highly contagious and transmission dynamics of COVID-19 are not yet fully elucidated. It is known that the ill person begins to become contagious before the symptoms of the disease begin. Also asymptomatic person who are infected but does not have symptoms and signs, can infect other individuals. The only way for health workers to protect themselves from COVID-19 is proper use of personal protective equipment and to ensure hand hygiene. COVID-19 is transmitted through close contact and large respiratory droplets and not transmitted by airborne. The surgical mask prevents the passage of respiratory droplets. However, during the aerosol producing procedures performed on the patient, small particles containing infectious particles are scattered to air in high amounts. Healthcare workers are more likely become infected during these procedures. It is recommended to wear respirator during these procedures. Use of masks or respirators must be in conjunction with other recommended PPE and appropriate hand hygiene.
