SARS-CoV-2 or novel coronavirus enters in human body through nose and mouth, stays there for a while. Then binds with ACE2 receptor, enters inside cell, multiply there and manifests. Again, Polyvinyl Pyrrolidone or Povidone Iodine (PVP-I) is a strong microbicidal agent having 99.99% virucidal efficacy in its only 0.23% concentration, irrespective of all known viruses, even in SARS-CoV-2 (in vitro). An oro-nasal spray is designed to apply the PVP-I in nose and oral cavity to gain a protective layer or coating over nasal and oral mucosa, so that SARS-CoV-2 can't bind with the ACE-2 receptor and prevent their entry inside. So, it will be effective for prevention of COVID-19. Moreover, as PVP-I has the ability for destruction of SARS-CoV-2, transmission of SARS-CoV-2 from patient will be reduced also. Thus PVP-I oro-nasal spray can act as an effective shield for COVID-19 protection for healthcare workers, for all.
