[Health Channel/Comprehensive Report]With the opening of the swimming pool, many people are gradually willing to go swimming, but there are still many people who worry that they may contract Wuhan pneumonia (new coronavirus disease, COVID-19) because they don’t wear a mask while swimming. In this regard, some doctors pointed out that there is no research to prove the infectivity of human infection through water sources or contaminated drinking water, and there is no research to prove the existence of infectivity in water.

Wu Yicheng, a sports medicine department and rehabilitation specialist at Lianxin International Clinic“Dr. Wu Yicheng-Sports Medicine Rehabilitation Medicine”The article pointed out that the new coronavirus can survive in the human body and cannot be transferred to some swimming pool water. The new coronavirus is relatively unstable in the water environment, and its activity in the water decreases faster. In addition, it is relatively for disinfected water substances (such as chlorine). It is sensitive and cannot be transmitted in swimming pools. It is different from norovirus and enterovirus that can survive in the water for several days and will still partially survive disinfection.

According to research, the resistance of the new coronavirus to chlorine is lower than that of bacteria. Therefore, the current disinfection methods for swimming pools can effectively reduce the number of bacteria and non-mantle viruses. It is also effective for new coronaviruses with a mantle. The filtered water contains new coronaviruses. The activity decreases faster, because the suspended matter in the water provides partial protection of the adsorbed virus, reduces the suspended matter, and effectively reduces the possibility of the spread of the new coronavirus. At present, there is little research evidence of the new coronavirus in the waters, and there is no research to prove that humans pass through the water source. Or contaminated drinking water infection, as opposed to droplet infection in confined spaces, no studies have confirmed the existence of infectivity in water.

Wu Yicheng said that from the perspective of public health, epidemic prevention is definitely the primary goal, but the blockade of sports venues or facilities not only interrupts the training of many people, but also means reducing the amount of physical activity and the future proportion of healthy people, especially in the need for sports intervention. Ethnic groups, including children, the elderly, pregnant women, people with disabilities, etc.

Wu Yicheng believes that WHO and other countries (the United States, Italy, France, etc.) have relevant standards for outdoor swimming and swimming pool epidemic prevention regulations. It is the best policy for swimming pool management to implement epidemic prevention measures. Formulate risk assessment standards and hazard analysis. Continuously check the current epidemiological situation, provide epidemic-related training and regular screenings for in-service employees and coaches, provide adequate health and epidemic prevention information for entering swimmers, and do a good job of monitoring and temperature measurement, symptom records, and through Appointment time, one-way path planning, non-sharing of lockers and shower spaces, etc., can reduce unnecessary contact and risk of infection among swimmers.
