Stopping the spreading of the coronavirus on surfaces

The explosive speed with which the cases of COVID-19  have spread in Spain  has forced the Ministry of Health to recommend  the disinfection of all surfaces. Avoiding  the transmission of virus among people is the objective  of using virucidal disinfecting products. All the work centres, homes and even the products received or delivered to customers ought to pass daily through a strict protocol of disinfection.


Objective: prevent spreading the virus among people.

To stop the propagation of Covd-19 it is absolutely necessary for the continuing of the human species and also for professional reasons. Any small drop originated by a cough by someone infected with the virus, can be breathed by another person if the right safety distance is not kept.


What happens when the respiratory drop is produced over a surface?

The time during which the virus remains alive in the surfaces is as much as 72 hours, being the metallic or plastic surfaces where the viral load remains for most time. On other surfaces such as stone or cardboard the presence of the virus remains for as much as 24 hours, and, therefore, its capacity to be contagious.

Touching these surfaces where the drops with the virus have fallen make our hands direct transmitters of the infection. If with our now  already infected hands we touch our mouth, nose or eyes, we let the Covd-19 enter our lungs. A study conducted in Australia, in the University of New South Wales, indicates that we touch our face on an average of 23 times an hour.


How to avoid the contagion originated by touching the surfaces?

 A virucidal disinfectant based on alcohol is the only way to stop the contagion originated on the surfaces. The virus is characterised by having an exterior layer of fat which protects it from destruction and makes its adhesion easier. Attacking the exterior fat layer that protects the virus and eliminates its proteins, this is the objective of these virucidal disinfectants , with alcohol as the main component.


What is the difference between a virucidal disinfectant and a bacterial disinfectant?

 It is very important no to confuse the type of disinfectant that we should use because of the danger of transmission. Only the virucidal disinfectants attack the virus. The bacterial disinfectants only attack the bacteria and  fungus  but do not destroy the virus. Both for all types of surfaces , as well as for protecting our hands, we should use only virucidal products. And the virus will be destroyed before spreading and infecting others.
