On February 12, 2021, Winter Storm Uri hit the United States. To understand the disaster-related causes and circumstances of death, the Centers for Disease Control and Prevention (CDC) activated media mortality surveillance.

The team searched the internet daily for key terms related to Uri and compiled the information into a standardized media mortality surveillance database to conduct descriptive statistics.

Between February 12 and March 2, 2021, the accessed media reported 136 Uri-related deaths from nine states. Most decedents were male (39%) and adults (62.5%). Exposure to extreme temperatures (47.1%) was the most common cause of death. Among indirect deaths, motor vehicle collision (12.5%), and carbon monoxide poisoning (7.4%) represented the top two circumstances.

This was the first time CDC activated media mortality surveillance for a winter storm. Media mortality surveillance is useful in assessing the impact of a disaster and provides timely data for an all-hazards response approach.

This project aimed to quantify and compare Massachusetts and Georgia public school districts’ 2017–2018 winter-storm-related Twitter unplanned school closure announcements (USCA).

Public school district Twitter handles and National Center for Education Statistics data were obtained for Georgia and Massachusetts. Tweets were retrieved using Twitter application programming interface. Descriptive statistics and regression analyses were conducted to compare the rates of winter-storm-related USCA.

Massachusetts had more winter storms than Georgia during the 2017–2018 winter season, but Massachusetts school districts posted winter-storm-related USCA at a 60% lower rate per affected day (adjusted rate ratio, aRR = 0.40, 95% confidence intervals, CI: 0.30, 0.52) than Georgia school districts after controlling for the student enrollments and Twitter followers count per Twitter account. A 10-fold increase in followers count was correlated with a 118% increase in USCA rate per affected day (aRR = 2.18; 95% CI: 1.74, 2.75). Georgia school districts had a higher average USCA tweet rate per winter-storm-affected day than Massachusetts school districts. A higher number of Twitter followers was associated with a higher number of USCA tweets per winter-storm-affected day.

Twitter accounts of school districts in Massachusetts had a lower tweet rate for USCA per winter-storm-affected days than those in Georgia.
