The constant concern with disinfecting all surfaces may even be an excess, but the World Health Organization continues to recommend it, if only because it gives greater “tranquility to the population”. And in excess why? Because, at least for now, there is no evidence to conclude that infection with the new coronavirus – responsible for Covid-19 – is transmitted through contact with contaminated surfaces.
The information appears in the latest WHO report, where the recommendation to disinfect surfaces and objects is maintained “whenever possible”, according to the El Mundo newspaper. This information comes after some studies point to the survival of the virus on some surfaces for up to 72 hours, which justified the need for constant disinfection of surfaces or hands right after touching surfaces such as keyboards, door handles or others.
Covid-19. How long does the virus survive on surfaces and in the air?
The WHO recalls that studies on the survival of the new coronavirus on surfaces were carried out in the laboratory "far from real world conditions", which may influence the survival of the virus. "Covid-19 disease is transmitted mainly through close physical contact or by droplets", can be read in the WHO document.
"At the time of publishing this report, it was not possible to draw conclusions about contact with a surface and the contagion of the disease, according to available studies," adds WHO in the report.
Even so, it will continue to be important to maintain surface hygiene regularly, according to the current recommendations of the Directorate-General for Health in various places: hospital environment, in companies, at home or in schools (with the return of children to daycare centers and 11th and 12th grade students this Monday).
