None. The virus that causes COVID-19 is an emerging viral pathogen that is classified as a human corona virus. It has been given the official name SARS-CoV-2 which stands for Severe Acute Respiratory Syndrome-Corona Virus #2 (the first SARS human corona virus was discovered in 2003). In general, previously discovered human corona viruses are known to be easily inactivated by many disinfectants. However, the agency that regulates disinfectants called the EPA (Environmental Protection Agency) has an emerging pathogens policy that was recently triggered by the COVID-19 crisis. That policy states that the primary registrant of a disinfectant formula can apply to make off label kill claims for an emerging pathogen if that disinfectant has efficacy claims for a more difficult to kill pathogen. Some examples of more difficult to kill viral pathogens (than human corona virus) include NOROVIRUS, and Canine Parvovirus.
