Olfactory Dysfunction: A Clinical Marker of COVID-19.

Area of Science:

• Infectious Diseases
• Otolaryngology
• Public Health

Background:

• The global spread of SARS-CoV-2 has overwhelmed healthcare systems, creating medical resource scarcity.
• Identifying indicators for hospital admission is crucial for efficient resource management.
• Olfactory impairment is a recognized symptom of COVID-19, though often underreported due to its perceived benign nature.

Purpose of the Study:

• To highlight the significance of olfactory impairment as an indicator of COVID-19.
• To emphasize the need for recognizing and reporting olfactory dysfunction for better patient management and resource allocation.

Main Methods:

• Review of scientific literature and reports on COVID-19 symptoms.
• Analysis of the prevalence and impact of olfactory dysfunction in COVID-19 patients.
• Examination of recommendations from scientific societies regarding olfactory symptoms.

Main Results:

• Olfactory dysfunction is a common symptom in COVID-19, with variable reported prevalence.
• Underreporting of olfactory impairment is likely, potentially due to its classification as a minor symptom.
• Scientific bodies acknowledge olfactory dysfunction as a frequent COVID-19 symptom and have issued guidance.

Conclusions:

• Olfactory impairment is a key indicator of COVID-19 infection.
• Increased awareness and reporting of olfactory dysfunction are necessary for effective healthcare.
• Addressing olfactory symptoms is vital for optimizing medical resource allocation during the pandemic.
