Decontamination of the Respiratory System, Propitious COVID-19 Countermeasure

Reza Bozorgipour

The COVID-19 pandemic has caused many crises, losses, and damages to people's livelihoods. Around 648 million confirmed corona cases resulted in 6642000 direct deaths globally as reported by Dec 16, 2022. COVID-19 is caused by a single-stranded RNA virus with dynamic nature as evolving, producing virulent mutants. The virus is airborne and highly contagious, and the principal transmission and penetration routes are through the respiratory system. Over 13 billion doses of vaccines have been administered by this time. Most countries have experienced a few surges by now. In spite of implementing healthcare protocols, restrictions, and vaccination the pandemic is ongoing even with the decline. Although vaccination is the most essential and urgent solution this alone may not resolve the issue in long term. None of the approved vaccines confer absolute immunity or zero transmission. Besides, there are concerns about their longevity and efficacy of them as the new variants may evade current vaccines. Moreover, there are people with allergic reactions to the vaccines, and their long-term side effects are not yet known. Nevertheless, vaccination is a unilateral preventive measure and supplementary countermeasures are needed. Thus, a multilateral approach is required to contain the pandemic. COVID-19 is primarily a respiratory disease. The establishment of reliable procedures for regular disinfection of the respiratory system may help restrain the pandemic.  In this proposal piece, a condensed description of traditional approaches to respiratory infectious illnesses is provided. These may inspire the development of preventive packages to protect people fairly against this contagious disease.
