This page contains resources associated with multiple studies (completed and ongoing) focusing on COVID-19 (scroll down).
Syndromic surveillance: we are utilizing real-time social media data, natural language processing and machine learning methods to identify and track symptom distributions over time.
Localized outbreak detection: we are combining retrospective data from social media with data from GDPH to train AI algorithms that can detect patterns in social media chatter indicative of localized outbreaks.
Toxicosurveillance: we are building methods that can detect unapproved treatments that are promoted for treating COVID to identify potential toxic exposures.
MOUD treatment access during COVID: in line with our past work, we are studying how COVID is affecting SUD and OUD treatment programs.
COVID and mental health: we are studying the impact of COVID on mental health using social media mining methods.
Impact of COVID on national services such as Medicaid.
