Summary

This completed study enrolled over 1,000 people in the Dominican Republic to track how COVID-19 spreads and how to control it. Researchers provided some households with alcohol-based hand sanitizer and monitored handwashing habits, virus exposure, and vaccine attitudes. The goal was to understand transmission and test simple prevention measures.

alcohol-based hand sanitizer
What this could lead to
