这样做有害身心，而且并不会降低感染者通过飞沫或接触而传播病毒的能力。
This practice could be physically and psychologically harmful and would not reduce an infected person’s ability to spread the virus through droplets or contact.
Even if someone who is infected with COVID-19 goes through a disinfection tunnel or chamber, as soon as they start speaking, coughing or sneezing they can still spread the virus.
The toxic effect of spraying with chemicals such as chlorine on individuals can lead to eye and skin irritation, bronchospasm due to inhalation, and potentially gastrointestinal effects such as nausea and vomiting.
In addition to health safety concerns, the use of chlorine in large-scale spraying practices may prevent this resource from being used for important interventions such as drinking water treatment and environmental disinfection of health care facilities.
