Sars contact number11/14/2022 Given that a minority of infected patients may remain asymptomatic, and that rapid and reliable screening remains limited, prevention against viral exposure has primarily focused on Personal Protective Equipment (PPE). Various anecdotes confirm a relatively high prevalence of COVID-19 among otorhinolaryngologists, and for this reason, special precautions have been proposed for many aerosol-generating transnasal procedures. Intubation, as well as transoral and transnasal procedures, may pose a unique risk as viral particles may be aerosolized while performing these measures and contact with mucosa can be extensive. The virus may reside in high concentrations in the nasal cavity, nasopharynx, oral cavity and oropharynx, and thus opportunities for dissemination of SARS-CoV-2 in the operating suite have been hypothesized. SARS-CoV-2 can remain aerosolized for at least three hours under experimental conditions and may persist for greater than 72 h on plastic and stainless steel surfaces this creates substantial risks to all healthcare professionals. The COVID-19 pandemic has increased awareness of operating room transmission risks of the responsible virus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Such an approach represents a low-cost, low-morbidity measure that may reduce the risks associated with aerosol-generating procedures performed commonly in otorhinolaryngology operating rooms. Thus, we propose a prophylactic treatment protocol for the application of topical povidone-iodine to the upper aerodigestive tract. Povidone-iodine also has good profile for mucosal tolerance. Numerous studies have confirmed that povidone-iodine inactivates many common respiratory viruses, including SARS-CoV-1. Current efforts to mitigate this risk focus on Personal Protective Equipment, including high-efficiency filtration as well as other measures.īecause the reservoir for SARS-CoV-2 shedding is in the nasopharynx and nasal and oral cavities, the application of viricidal agents to these surfaces may reduce virus burden. The COVID-19 pandemic has raised concerns of inadvertent SARS-CoV-2 transmission to healthcare workers during routine procedures of the aerodigestive tract in asymptomatic COVID-19 patients.
