Epidemiological Observation From a Smartphone Self-monitoring Application for Suspected COVID-19 Patients' Triage (COVID CALL 15)

Smartphone Self-monitoring Application for Suspected COVID-19 Patients' Triage

Sponsored by Weprom

A coronavirus pandemic began on 12/31/2020 with the first Chinese patient. As of 3/16/2020, the epidemic affects more than 100 countries with 169,000 official infections and 6,500 deaths. This virus causes a pathology ranging from simple flu symptoms in 80% of cases to acute respiratory distress syndromes requiring resuscitation in 5% of cases and a death rate of 1.4 to 4% of cases.

The arrival in France on 02/25/2020 with an exponential development of the infection (more than 5,000 cases on 03/15/2020) was accompanied by an unprecedented number of calls to the French emergency service call number (15) of worried patients with overload and sometimes saturation of the service that can impact calls and the care of patients really recovering from an emergency.


Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.

What should I expect?

The web application https://www.maladiecoronavirus.fr/ was developed with a group of physicians from the Institut Pasteur, Hospitals group of Paris, Hospitals of Lille and Rennes and the ILC Jean Bernard in Le Mans. It makes it possible to guide symptomatic patients and patients who wishing to know what to do (call their general practitioner, teleconsultation, or call emergency service) based on symptoms and predictive factors of severity.

Following the availability of this new tool, we want to assess the impact of the application on the number and relevance of calls to emergency service.
