ILI-NH - Influenza-like illness (including COVID-19) sentinel surveillance in Belgian nursing homes

The objective of ILI_NH is to signal and monitor start, duration and intensity of influenza-like illness or ILI (including COVID-19) waves/appearances among nursing homes (NH) residents to optimize and support provided health-care, -planning, -management and -policies. In addition, ILI_NH monitors locally circulating virus types/subtypes or lineages/sub-lineages and their relationship to global and regional patterns. We have an aggregated dataset on NH level with ILI-cases, ILI-related hospital admissions, and deaths in NH, for the whole season. We have anonymized sample data of nursing home residents with linked epidemiological data between October and May of each season.

Purposes

  • Primary objectives To establish a sentinel NH network geographically representative for the Belgian NH population with the aim to monitor ILI (including COVID-19). To signal and monitor start, duration and intensity of ILI (including COVID-19) waves/appearances among NH residents to optimize and support provided health-care, -planning, -management and -policies. To monitor locally circulating virus types/subtypes or lineages/sub-lineages and their relationship to global and regional patterns. Secondary objectives To monitor other COVID-19 or influenza-related aspects such as vaccine coverage, variant detection, etc., according to needs and wishes

Provenance
  • For the epidemiological/clinical part, the data for ILI_NH comes from the weekly questionnaire created in LimeSurvey and maintained by Sciensano. For the virological part, the data for ILI_NH comes from samples sent by the nursing homes and analysed by the National Reference Center Influenza. Data on the nursing home resident (anonymised) is obtained through the LimeSurvey questionnaire maintained by Sciensano.
