Test-and-treat for Influenza in Homeless Shelters

2019-10-31 14:29:34 | BioPortfolio


This study is a stepped-wedge cluster-randomized trial of on-site rapid testing and treatment for influenza in homeless shelters within the Seattle area to determine whether this strategy reduced the incidence of influenza in the shelter environment.


The study will be conducted over the course of two flu seasons, and all shelters will start with routine surveillance of influenza using mid-turbinate nasal swabs for sample collection and RT-PCR testing. Shelters will be randomized to implement a test-and-treat strategy at different months throughout flu season, treating individuals who present ARI symptoms or new or worsening cough within 2 days (48 hours). Shelters will continue routine surveillance until all offer the test-and-treat strategy. Eligible individuals will be tested on site with a point-of-care molecular influenza test and, if positive, offered antiviral treatment. Individuals with 3-7 days of symptoms, or who choose not to participate in the intervention strategy, will still be eligible for participation in the routine surveillance.

Our primary hypothesis is that implementation of a point-of-care diagnostic and antiviral treatment intervention among sheltered individuals experiencing homelessness will reduce the incidence of influenza within this population over the course of a flu season. A process evaluation will also be conducted to explore the feasibility of point-of-care testing implementation in this population.

Medical and Biotech [MESH] Definitions

Allows patient diagnoses in the physician’s office, in other ambulatory setting or at bedside. The results of care are timely, and allow rapid treatment to the patient. (from NIH Fact Sheet Point-of-Care Diagnostic Testing, 2010.)

Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.

Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.

Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.

A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.
