Health Desk- May 18, 2020: 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) has warned.
In a document on cleaning and disinfecting surfaces as part of the response to the virus, the WHO on Saturday said spraying can be ineffective.
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".
Spraying chlorine or other toxic chemicals on people can cause eye and skin irritation, bronchospasm and gastrointestinal effects, it adds.
The organisation is also warning against the systematic spraying and fumigating of disinfectants on to surfaces in indoor spaces, citing a study that has shown it to be ineffective outside direct spraying areas.
However, no precise information is currently available for the period during which the viruses remain infectious on the various surfaces.
