LONG TERM OUTCOMES OF COVID-19 AND INFLUENZA (LOCI)

Individuals hospitalized with severe influenza and COVID-19 can experience both serious in-hospital outcomes as well as long term impacts to health following their illness. The long-term consequences of either infection remain largely unknown. The primary aim of this study is to examine individual long-term recovery following hospitalization due to influenza or COVID-19 illness. We additionally aim to create an improved measure of illness severity by following hospitalized patients after discharge and comparing their functional status from hospitalization to that during their long-term recovery to assess the relationship between traditional in-hospital severity outcomes and long-term functional status after discharge.

MEDICALLY ATTENDED RSV ILLNESSES: DAY CARE VIRUS TRANSMISSION STUDY WITH UNIVERSITY OF PITTSBURGH

The overall goal of this study is to describe the epidemiology of SARS-CoV-2 transmission among children in child care, their child care providers, and their household contacts in order to create evidence-based policies and practices for safely operating group child care. Participating children and providers are swabbed weekly and complete regular surveys. The specific objectives to accomplish the overall goal are to:

  1. Determine prior SARS-CoV-2 infection,
  2. Detect new infections, and
  3. Detect secondary infections.


VACCINE EFFECTIVENESS AND IMMUNOGENICITY IN HEALTHCARE WORKERS (ISRAEL)

Center investigators have participated in multiple studies of influenza vaccination effectiveness and immunogenicity, working with healthcare workers at multiple hospitals in Israel, where influenza vaccination is not mandated for this population. This work has included a multi-year prospective cohort and a randomized trial of enhanced influenza vaccines. 

HAIVEN (HOSPITALIZED ADULT INFLUENZA VACCINE EFFECTIVENESS NETWORK)

The Center was a participating site in the CDC funded HAIVEN Network for over 6 years. The HAIVEN network ended in July 2021. The Center now participates in the CDC funded IVY network to measure vaccine effectiveness in the hospitalized population. Information about the CDC’s HAIVEN Network.
