WHO (World Health Organization), through a communiqué titled – ‘Cleaning and disinfection of environmental surfaces in context of COVID-19 – warned that the routine application of disinfectants to environmental surfaces by spraying or fogging is not recommended for COVID-19.

The interim guide made for health care professionals and authorities mentions that spraying as a primary disinfectant strategy in indoor spaces is ineffective in removing contaminants outside of direct spray zones. Moreover, spraying disinfectants can result in risks to the eyes, respiratory or skin irritation and the resulting health effects, Spraying or fogging of certain chemicals such as formaldehyde, chlorine based agents or quaternary ammonium compound is not recommended due to adverse health effects on workers in facilities where these methods have been utilized, as per the communiqué.

WHO also said that spraying or fumigation on outdoor spaces like streets or marketplaces was also not recommended to kill COVID-19 virus or other pathogens, as the disinfectant is inactivated by dirt and debris and it is not feasible to manually clean and remove all organic matter from such spaces. Spraying porous surfaces, such as sidewalks and unpaved walkways, would be even less effective.

Spraying individuals with disinfectants is not recommended under any circumstances, said WHO guidelines, as it can physically and psychologically harm the individual and it would not reduce an infected person’s ability to spread the virus through droplets or contact.
