The World Health Organization (WHO) warned on Saturday that spraying antiseptics on the streets, as is the case in some countries, does not eliminate the emerging coronavirus and carries health risks.
In a document on cleaning and disinfecting surfaces as part of the fight against Covid-19, the World Health Organization said spraying these materials may be ineffective.
The document states that "sprinkling in open spaces such as roads and markets (...) is not recommended for killing the Covid-19 virus or other pathogens because the disinfectant loses its effect to dirt and debris."
"Even in the absence of organic materials, it is unlikely that the spraying of chemicals will adequately cover all surfaces for a period that will allow the elimination of pathogens," she added.
The World Health Organization considered that the streets and sidewalks are not "reservoirs of infection" Covid-19, adding that spraying antiseptics may be "harmful to human health."
The document also stressed that spraying individuals with antiseptics "is not recommended under any circumstances", as "it may be physically and psychologically harmful and does not reduce the ability of the person to spread the virus."
She noted that spraying chlorine or other toxic chemicals on humans can cause skin infections or in the eyes.
The organization also warned against continuous spraying of indoor surfaces, citing a study that showed that this would be effective only in areas that are directly sprayed.
"If disinfectants are used, this should be done by soaking a cloth or mop with disinfectant," she added.
The emerging coronavirus can stick to surfaces, but there is currently no accurate information on how long it will be able to spread.
Studies have shown that the virus can survive on several types of surfaces for days, but this period remains theoretical because it was determined in laboratory conditions and should be "interpreted with caution".
