Management of acute upper respiratory tract infection: the role of early intervention.

IntroductionUpper respiratory tract infection (URTI) is an illness caused by an acute infection by viruses or bacteria of the nose, sinuses, pharynx, and larynx. Most URTIs are short, mild, and self-limiting, but some can lead to serious complications, resulting in heavy social and economic burden on individuals and society.Areas coveredThis article presents the management guidelines and consensus established through the Delphi method during an expert roundtable conducted in November 2020 and results of a targeted literature review.Expert opinionThere is currently no available cure for acute URTI and management strategies aim towards symptom alleviation and prevention of URTI virus transmission. The effectiveness of these strategies is highly increased with early intervention, administered prior to the peaking of viral shedding. This reduces the chances of developing a full-blown acute URTI, decreases symptom severity, and reduces viral transmission. Mucoadhesive gel nasal sprays have shown promising results for early intervention of acute URTI. They act by creating a barrier that can trap virus particles, thereby preventing invasion of the mucosa by the virus. Additionally, they deliver broad spectrum activity that is effective against a wide variety of pathogens that cause acute URTI. Acute URTI warrants greater attention and proactive management in reducing its burden
