Spraying disinfectants can be dangerous for human health, says WHO
The World Health Organization criticized the popular method of protection against the novel coronavirus. The WHO considered the method not only ineffective, but also having a negative impact on health.
In a document of cleaning and disinfecting surfaces as part of the response to the virus, the WHO says that spraying or fumigating of disinfectants in indoor spaces is not effective and doesn’t adequately eliminate the novel coronavirus. In addition, spraying disinfectants can result in damaging eyes, respiratory system or skin.
The international organization said that if the disinfectants are to be applied, this should be done with a cloth or wipe soaked in disinfectants, but first it is necessary to remove organic matter from the surface with a brush or a scraper.
“Spraying or fogging of certain chemicals, such as formaldehyde, chlorine-based agents or quaternary ammonium compounds, is not recommended due to adverse health effects,” said WHO in an updated advisory on infection control.
The WHO also says that spraying disinfectants on the streets and in the yards isn’t effective in killing the COVID-19 virus because disinfectant is inactivated by dirt and debris. In addition, spraying chlorine or other toxic chemicals on people can cause eye and skin irritation, bronchospasm, nausea and vomiting. At the same time, this method would not reduce the airborne transmission of the novel coronavirus.
