Significance and Purpose

Significance: Make it easier for public health and public safety workers to get current location-specific SARS-CoV-2 airborne or surface decay estimates

Purpose: Develop R shiny app to provide airborne and surface decay estimates for specific US cities based based on current weather forecasts and recent DHS models (as of June 15th, 2020)
