Virological Surveillance of Acute Respiratory Infection in Primary Health Care in Metropolitan France

Condition(s) studied

Investigational drug(s) / intervention(s)

saliva sampling: Based on the protocol, physicians perform either a nasopharyngeal swab or saliva collection on included patients. The method is determined by scientific data and epidemiological constraints, not by the patient. Saliva collection: The physician oversees the collection during the visit using the provided kit (pipette, tube, etc.). Depending on constraints, the patient may perform the collection at home if agreed upon. If the patient is unable to self-collect (e.g., infants, facial paralysis), the physician collects the saliva directly from under the tongue using the pipette.

Nasopharyngeal swab: Based on the protocol, physicians perform either a nasopharyngeal swab or saliva collection on included patients. The method is determined by scientific data and epidemiological constraints, not by the patient. Nasopharyngeal sampling: During the consultation, the physician performs a deep nasal swab using the provided kit (FFP2 mask, swab, transport tube, absorbent, SafetyBag, and pre-paid envelope for partner labs).

Study summary

Every year in the fall and winter, numerous respiratory viruses (such as influenza viruses, SARS-CoV-2 (COVID-19), RSV, rhinovirus, and metapneumovirus) circulate in mainland France, causing acute respiratory infections (ARIs). These viruses can cause epidemics of varying severity, requiring close monitoring to determine their circulation levels and adapt public health measures accordingly. In France, ARI surveillance relies on two networks: the Sentinelles network in primary care and the RENAL network in hospitals. The Sentinelles surveillance is conducted in collaboration with Santé publique France, the National Reference Center for Respiratory Infection Viruses (Institut Pasteur and Hospices Civils de Lyon), and the University of Corsica. As part of the virological surveillance of ARIs, Sentinelles physicians are asked to collect nasopharyngeal swabs or saliva samples from a sample of patients presenting with an ARI during their clinic visits. This surveillance makes it possible to identify respiratory viruses circulating in primary care (general practice and pediatrics), to describe confirmed cases for each of the circulating viruses, and to estimate the impact of each on general practice. This surveillance also allows for the evaluation of the effectiveness of vaccines against influenza and COVID-19.

Eligibility
