Public health France published, on July 21, 2022, the results of its first study on Covid long.
“Long COVID” or “post-COVID-19 disease” is characterized by long-lasting or persistent symptoms after initial infection.
According to the definition of the World Health Organization (WHO), “post-COVID-19 disease” or “long COVID” generally appears within 3 months of the initial infection with SARS-COV-2 and is characterized by symptoms, persisting for at least 2 months, which cannot be explained by other diagnoses and have an impact on daily life. (The WHO publishes a 1st official definition of Covid Long)
The list of 25 eligible symptoms includes: fatigue, cough, shortness of breath, malaise after exercise, intermittent fever, loss of taste or smell, depression, cognitive dysfunction.»
The study was conducted online in March and April 2022 with a representative sample of 27,537 people.
Among the respondents, 4% met the criteria for a “post-COVID-19 condition”, according to the WHO definition, i.e. 30% of those questioned who had had an infection with SARS-CoV-2 for more than three months. previously. At the scale of the French population at the time of the study, the “post-COVID-19 condition” would thus concern 2.06 million people over the age of 18.
The prevalence of “post-COVID-19 disease” decreased with time after the date of SARS-CoV-2 infection. However, 18 months after infection, 20% of people who had the infection still met the criteria for long Covid.
The healthcare professional most consulted by patients with a “post-COVID-19 condition” was the general practitioner (87%). Next came specialists in pneumology (16%), neurology (11%) and infectiology (5%). Nearly 11% of respondents with a “post-COVID-19 condition” did not seek care in the 12 months preceding the survey.
However, the results of the study should be interpreted with caution.“, highlighted Public health France. “
Although the method makes it possible to ensure the representativeness of the sample, the results are based on a sample made up of volunteers recruited from a panel. The reported proportion of people who have been infected with SARS-CoV-2 is however comparable to that estimated by surveillance systems.»
This work will continue with a second study on a random sample in the general population, in order to produce more robust estimates of the prevalence and impact of post-COVID-19 disease on the use of care, mental health and life quality.»
