Communities, Households and SARS-CoV-2 Epidemiology (CHASING) COVID

The novel coronavirus (aka SARS-CoV-2 or COVID-19) pandemic has dramatically transformed life for the entire United States in a matter of weeks and has resulted in logistic, medical, and economic challenges for individuals, households, communities, and states. CHASING COVID is a national study to understand the spread and impact of COVID-19 on individuals, households, and communities across the country.

Initial objectives (early in pandemic):

Estimate and evaluate determinants of the incidence of SARS-CoV-2 infection, disease and death;
Assess the pandemic’s impact on psychosocial and economic outcomes (e.g., mental health, unemployment, food security); and
Assess the uptake of pandemic mitigation strategies (e.g., masking, testing, contact tracing, isolation/quarantine, vaccination).

Additional objectives (added later in pandemic):

Assess the incidence and risk factors for long COVID;
Assess the uptake of oral antivirals; and
Test a brief digital intervention aimed at decreasing undervaccination for COVID-19 in adults with mental health symptoms.
