According to researchers, widely available vaccinations may not be enough to stop the spread of the Covid-19 virus and its future variants. But using a nasal spray as a booster may help keep most of the population free from serious illnesses from the disease. It is learnt that robust antibody responses in the respiratory tract would neutralize the virus, preventing the establishment of viral infection and subsequent passing of the infection to others. Lancet Regional Health Southeast Asia has reportedly published successful phase 3 clinical trial results of Nitric Oxide Nasal Spray (NONS) treatment for Covid-19. According to researchers NONS was safe and well-tolerated in Covid patients. A nasal spray administered in high-risk adult Covid patients in India reportedly reduced viral load by 94 percent within 24 hours and 99 percent in 48 hours. According to medical experts this therapy has the potential to make a crucial contribution to COVID-19 management with its ease of use in the current highly transmissible phase of pandemic. Nitric oxide blocks entry into the nasal passage, kills the virus, and stops its replication, which is why viral load is reduced so rapidly with the nasal spray. Goa has seen a surge in the number of Covid-19 cases in the past few weeks. Some deaths due to the dreaded disease have also been reported. If the antiviral nasal spray is effective in reducing the viral load and preventing the spread of the infection, then it will be a further boost for the management of the disease.
