Data Collection
Data Collection
Data is collected in 3 different ways:
Clinical evaluation by phone call or directly in your medical file for hospitalized participants, to fill in the CRF (Case Report Form) adapted from ISARIC core CRF (PDF in English / French).
Online questionnaires: Adults and children above 10 years will be asked to complete an online questionnaire on your health once a day, for 14 days, then once a week for the next two weeks and once a month during the year. The last monthly questionnaire will be more detailed in order to evaluate long-term health related consequences of Covid-19 (more information). Children questionnaires have been adapted with the contribution of pediatric specialists.
Voice recording using the Colive LIH smartphone application: Adults and children above 10 years will be offered to participate in audio recordings regularly, with the same frequency as for the online questionnaires (more information on the Colive LIH app which can be viewed in French here).

Colive LIH App
Colive LIH is a smartphone application developed by the IT team of DOPH from LIH and available on both Apple and Google play stores.
The app enables the collection of participant’s voice recordings with the objective of identifying vocal biomarkers associated with frequent symptoms related to COVID-19 (such as fatigue or respiratory problem).
Each participant is invited to perform 2 different voice recordings daily over 14 days, then weekly until week 4 and monthly until month 12. A first recording consists in reading a predefined text, while a second one consists in saying “Aaaaah” as long as possible.
Languages supported: French, German, Portuguese and English.
