The SARS-CoV-2 viral infection pandemic has altered health and disinfection protocols in many public places. Swimming pools are one of the most dangerous places for COVID-19 outbreaks. This article examines the mechanism and rate of transmission of the SARS-CoV-2 virus and its resistance to treatment systems to purify swimming pool water by chlorine and UV. This review is based on reports and protocols from organizations and centers such as the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC). Studies show that free chlorine with a concentration of 1-3 ppm along with the implementation of a well-written program for the treatment system with proper operation will inactivate and remove the COVID-19 virus from the pool water. In addition, maintaining social distance and reducing the number of swimmers by 50% of the usual number can significantly reduce the risk of person-to-person transmission.
