On average, they survive between four and five days. "Low temperature and high air humidity further increase their lifespan," points out Kampf.</p>
<p>Tests with various disinfection solutions showed that agents based on ethanol, hydrogen peroxide or sodium hypochlorite are effective against coronaviruses. If these agents are applied in appropriate concentrations, they reduce the number of infectious coronaviruses by four so-called log steps within one minute: this means, for example, from one million to only 100 pathogenic particles. If preparations based on other<span> </span><a href="https://medicalxpress.com/tags/active+ingredients/" rel="tag" class="textTag">active ingredients</a><span> </span>are used, the product should be proven to be at least effective against enveloped viruses ("limited virucidal activity"). "As a rule, this is sufficient to significantly reduce the risk of infection".</p>
