The practice of spraying disinfectants on streets by many countries does not kill the new coronavirus and can also pose as a health risk for many, warned the World Health Organisation (WHO) on May 16.
In a document released by the WHO, spraying of disinfectants on surfaces as a part of the response to eliminate the coronavirus can be ineffective. “Spraying or fumigation of outdoor spaces, such as streets or marketplaces, is not recommended to kill the COVID-19 virus or other pathogens because disinfectant is inactivated by dirt and debris,” said WHO in the document.
WHO also mentioned in the document that streets and pavements are not considered as reservoirs of coronavirus and can be dangerous for the health of people.
The document also warned against the spraying of disinfectants on humans and said that it doesn’t recommend such procedures under any circumstances. “This could be physically and psychologically harmful and would not reduce an infected person’s ability to spread the virus through droplets or contact,” explained the document.
Common disinfectants comprising of chlorine and other toxic chemicals when sprayed on human skin can cause eye and skin irritation and when inhaled, can lead to gastrointestinal effects.
As per WHO, if disinfectants are to be applied on surfaces, it is recommended to do it with a cloth or wipe that has been soaked in disinfectant.
According to research by medical experts around the world, the SARS-CoV-2 virus responsible for COVID-19 pandemic can attach itself to surfaces and objects for a prolonged period of time.
However, there is no exact evidence as to how much time can the virus survive on different kinds of surfaces and object after attaching itself to them.
