CDC COVID-19 Surveillance Project


  • CDC requires research data to inform COVID-19 recommendations.
  • Abt leads network studies to assess risk and characterize disease epidemiology.
  • Delivery of data about key cohorts is ongoing.
The Challenge

CDC’s analysis of COVID-19 surveillance data informs public health policies, communication about protective behaviors, and guidance to public health and healthcare providers, communities, businesses, and schools. CDC contracted with Abt to conduct five studies to collect critical data from key populations:

  • Research on the Epidemiology of SARS-CoV-2 in Essential Response personnel (RECOVER) Study
  • Epidemiology of SARS-CoV-2 in Pregnancy and Infancy (ESPI) Network Study
  • Geisinger Electronic Cohort (GEICO) Study and Geisinger Prospective (GEIPR) Case-Control Study 
  • COVID-19 Illness and Testing among Retirement Communities in the US (CITRUS) Cohort Study
  • Coronavirus Household Evaluation and Respiratory Testing (C-HEaRT) Cohort Study
The Approach

Abt is leading a network of clinical partners conducting prospective cohort studies to assess such issues as:

  • household transmission of COVID-19
  • transmissibility of infection
  • rates of infection and illness
  • clinical epidemiology of the disease
  • characteristics of medically and non-medically attended COVID-19 cases.

To the extent possible, Abt is using the existing infrastructure set up to conduct network studies to assess risk and characterize disease epidemiology of novel influenza or other novel respiratory viruses among different cohorts.

The Results

Recruitment and data collection are currently under way for all the studies. Abt aims to recruit more than 8,000 participants for the five studies. We also are collecting electronic data from medical records for 40,000 hospitalized patients for secondary data analyses.
