Brief Summary
-----------------
This registry will allow to evaluate the correlation of the incidence and evolution of associated symptoms of infection of COVID-19 with the biological and clinical parameters in patients followed in Oncology during the COVID-19 pandemic.

Prior to conducting any of the screening tests, the Investigator or his designee will explain the trial fully to the prospective patient and provide him with a copy of the Patient Information Leaflet/Informed Consent Form.

At the end of the Observation Period, all patients will complete a series of questionnaires relating to the conduct of the study and tools employed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Obvio-19 App<br>If the patient is willing to participate to the trial, his given oral, free, informed and express consent will be collected and traced in his medical file. After enrollment, patients will be sent an invitation via email to download the Obvio-19 mobile app. After downloading the Obvio-19 app, patients will receive instructions as to how they may communicate with the study investigator. Communication may occur through the chat function of the app or live telephone conversations. Patients must log into the Obvio-19 app daily to complete the questionnaires. The Obvio-19 system is designed to identify responses that indicate the participant is at an increased risk for serious illness or exhibiting serious symptoms, such as coughing up blood. Such patients will be notified by the app of this status and prompted to seek medical attention. | Other: Obvio-19 app<br>* As part of this research, the patient must complete questionnaires daily on the Obvio-19 application, one of 5 minutes. Evaluation of the proportion of patients with COVID-19 infection's symptoms known to be associated with COVID-19 diagnosis (fever, cough, loss of taste and smell, sore throat, muscle pain, diarrhea, fatigue, difficulty eating and drinking and shortness of breath) followed during a period of 6 months. To assess the prevalence and course of symptoms of COVID-19 infection of patients followed during a period of 6 months. To establish the correlation of the COVID-19 infection with the biological and clinical data of patients from the Oncology cohort of the Groupe hospitalier Paris Saint-Joseph in Paris followed during a period of 6 months.<br>|
