Disinfecting streets does not eliminate coronavirus, poses health risk ― WHO

• Disinfecting streets does not eliminate coronavirus, Spraying disinfectant on the streets, as practised in some countries, does not eliminate the new coronavirus and even poses a health risk, the World Health Organization (WHO) warned on Saturday.
  

In a document on cleaning and disinfecting surfaces as part of the response to the virus, the WHO says spraying 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,” explains the WHO.

“Even in the absence of organic matter, chemical spraying is unlikely to adequately cover all surfaces for the duration of the required contact time needed to inactivate pathogens.”

The WHO said that streets and pavements are not considered as “reservoirs of infection” of COVID-19, adding that spraying disinfectants, even outside, can be “dangerous for human health”.

The document also stresses that spraying individuals with disinfectants is “not recommended 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,” said the document.
