How to distinguish Covid from colds and allergies

WHAT are the specific symptoms of Covid-19 and which are those of a common cold or allergic rhinitis? When to worry, for oneself and for others, and perhaps isolate yourself at home waiting for the outcome of a tampon, and when instead to continue living the same life as always, without prejudice to masks and interpersonal distance? A multicenter study published in Allergy and promoted by the ARIA group, (Allergic Rhinitis and its Impact on Asthma of the WHO and by EAACI, European Academy of Allergy and Clinical Immunology), helps to distinguish the symptoms of the upper respiratory tract of three diseases: colds, allergic rhinitis and Covid-19.
