Our Challenge

A Rapidly Spreading Disease

Data models inform public policy solutions to the COVID-19 crisis. Other models predict the spread of disease over large areas, overlooking local area effects that impact transmission rates.

Our Solution

A Precision Approach

CHOP PolicyLab Director, David Rubin, MD, MSCE, and colleagues develop a reliable data-based model that accounts for variables such as population, geography and temperature. The model provides insight on how a community’s current social distancing practices will affect the virus’s spread.

Moving Ahead

Taking Action

Our PolicyLab team continues to engage local and federal leaders to inform a safe reopening approach that accounts for the economic and social impacts shelter-in-place strategies have on low-income communities.

During the first week of our COVID-19 response, CHOP providers conducted more telemedicine visits than in the previous three years combined. We are now providing more than 2,000 telemedicine visits each day.
