Among the few positive news that can be had in this Pandemic caused by COVID-19, we find this article that we want to share with you. Just reading the summary is enough to know that Alcohol (Ethanol> 65%) and Hydrogen Peroxide or Oxygenated Water (> 0.5%) kill the virus in the minute they have contact with it.

The great news is that these disinfectants are inexpensive, easy to get, and non-corrosive, so they can be used in environments, surfaces, and utensils without any risk.

Currently, the emergence of a novel human coronavirus, SARS-CoV-2, has become a global health concern causing severe respiratory tract infections in humans. Human-to-human transmissions have been described with incubation times between 2-10 days, facilitating its spread via droplets, contaminated hands or surfaces. We therefore reviewed the lit- erature on all available information about the persistence of human and veterinary coronaviruses on inanimate surfaces as well as inactivation strategies with biocidal agents used for chemical disinfection, e.g. in healthcare facilities. The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62e71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05e0.2% benzalkonium chloride or 0.02% chlorhexidine digluc- onate are less effective. As no specific therapies are available for SARS-CoV-2, early containment and prevention of further spread will be crucial to stop the ongoing outbreak and to control this novel infectious thread.  ª 2020 The Healthcare Infection Society.

On different types of materials it can remain infectious for from 2 hours up to 9 days. A higher temperature such as 30○C or 40○C reduced the duration of persistence of highly pathogenic MERS-CoV, TGEV and MHV. However, at 4○C persistence of TGEV and MHV can be increased to 28 days. Few comparative data obtained with SARS-CoV indicate that persistence was longer with higher inocula. In addition it was shown at room temperature that HCoV-229E persists better at 50% compared to 30% relative humidity.
