Clinical features of 1487 COVID-19 patients with outpatient management in the Greater Paris: the COVID-call study.

Clinical features of COVID-19 have been mostly described in hospitalized patients with and without ICU admission. Yet, up to 80% of patients are managed in an outpatient setting. This population is poorly documented. In France, health authorities recommend outpatient management of patients presenting mild-to-moderate COVID-19 symptoms. The aim of this study was to describe their clinical characteristics. The study took place in an emergency medical dispatching center located in the Greater Paris region. Patients included in this survey met confirmed COVID-19 infection criteria according to the WHO definition. We investigated clinical features and classified symptoms as general, digestive, ear-nose-throat, thoracic symptoms, and eye disease. Patients were included between March 24 and April 6 2020. 1487 patients included: 700 (47%) males and 752 (51%) females, with a median age of 44 (32-57) years. In addition to dry cough and fever reported in more than 90% of cases, the most common symptoms were general symptoms: body aches/myalgia (N = 845; 57%), headache (N = 824; 55%), and asthenia (N = 886; 60%); shortness of breath (N = 479; 32%) and ear-nose-throat symptoms such as anosmia (N = 415; 28%) and ageusia (N = 422; 28%). Chest pain was reported in 320 (21%) cases and hemoptysis in 41 (3%) cases. The main difference between male and female patients was an increased prevalence of ear-nose-throat symptoms as well as diarrhea, chest pains, and headaches in female patients. General symptoms and ear-nose-throat symptoms were predominant in COVID-19 patients presenting mild-to-moderate symptoms. Shortness of breath and chest pain were remarkably frequent.
