Topic: Nasal Cavity

Dr. Peter McCullough recommends nasal hygiene as a primary defense against COVID-19, noting that the virus replicates in the nasal cavity. He suggests using diluted povidone iodine or hydrogen peroxide in a neti pot or spray bottle to kill the virus on contact. McCullough emphasizes that the virus is airborne and that targeting the nasopharynx is more effective than hand sanitizer.

Diluted povidone-iodine and hydrogen peroxide are identified as effective agents for killing the COVID-19 virus within the nasal cavity. Since the virus replicates primarily in the nasopharynx, regular use of neti pots or nasal sprays can reduce viral load and prevent systemic infection. These topical treatments are presented as a safer and more direct alternative to systemic pharmaceutical interventions.
