BACKGROUND: Although there are many asymptomatic patients, one of the problems of COVID-19 is early recognition of the disease . COVID-19 symptoms are polymorphic and may include upper respiratory symptoms . However, COVID-19 symptoms may be mistaken withthe common cold or allergic rhinitis . An ARIA-EAACI study group attempted to differentiate upper respiratory symptoms betweenthe three diseases .
METHODS: A modified Delphi process was used and ARIA members who were seeing COVID-19 patients were asked to fill in a questionnaire on the upper airway symptoms of COVID-19, common cold andallergic rhinitis .
RESULTS: Among the 192 ARIA members who were invited to respond to the questionnaire , 89 responded . 87 questionnaires were analysed . The consensus was then reported.A two-way ANOVA analysis revealed significant differences inthe symptom intensity between the three diseases (p <0.001).
CONCLUSIONS: This modified Delphi approach enabled thedifferentiationof upper respiratory symptoms betweenCOVID-19, common cold and allergic rhinitis . An electronic algorithm will be devised using the questionnaire.
