Gastroenteritis and respiratory infection outbreaks in French nursing homes from 2007 to 2018: Morbidity and all-cause lethality according to the individual characteristics of residents.

Background: Gastroenteritis (GE) and respiratory tract infection (RTI) outbreaks are a significant issue in nursing homes. This study aimed to describe GE and RTI outbreaks with infection and all-cause lethality rates according to the individual characteristics of nursing home residents.

Methods: Clinical and virological surveillance were conducted (2007 to 2018).

Influenza prevention in nursing homes: Great significance of seasonal variability and spatio-temporal pattern.

Objective: This work evaluated seasonal variations and spatio-temporal pattern of respiratory tract infections (RTI) in geriatric nursing homes in order to improve effective surveillance, prevention, control and management of RTI.

Methods: Prospective surveillance of RTI (Low Respiratory Tract infections and Influenza Like Illnesses) was conducted in 11 sites in Alsace over a 10-year period with clinical case definitions and rapid tests (Immunoassay) to identify influenza virus.

Results: Influenza national epidemic was a period at high risk of RTI in nursing homes with variable impacts depending on the seasonal period.

Influenza outbreaks management in a French psychiatric hospital from 2004 to 2012.

Objective: Influenza epidemics can have consequences in terms of morbidity and mortality for the patients. This work assesses influenza outbreaks in order to validate and optimize alert and control measures in a psychiatric hospital.

Method: The prospective monitoring of influenza episodes was conducted for 8 years in 19 units of a mental health hospital.
