CDC: How to mitigate COVID-19 transmission in densely populated areas globally

Coronavirus Disease 2019 (COVID-19) CDC provides credible COVID-19 health information to the U.S. CDC Centers for Disease Control and Prevention

High-density urban areas may face challenges implementing COVID-19 mitigation measures due to space limitations within and between households and limited water, sanitation, and hygiene (WASH) infrastructure.

This document provides suggestions for community mitigation measures in densely populated, international, low-resource settings and describes implementation considerations associated with each measure. Community mitigation activities are actions that people and communities can take to prevent or reduce local COVID-19 transmission. This document describes measures that both individuals and organizations can take to support households in high-density urban areas.

Document audience: This document is intended for use by any person, institution, or organization preparing for or responding to community transmission in high-density urban settings and for those assisting those organizations (federal and local governments, CDC country offices, and others). It contains special considerations for low-resource, international settings.

Layered approach: Mitigation measures can be organized into three categories: personal controls, administrative controls, and engineering controls. These should be layered to reduce overall risk of COVID-19 transmission. In this document, personal controls are primarily limited to actions that individuals can take to prevent transmission within households, whereas administrative and engineering controls are actions that communities, organizations, and governments can take to prevent transmission between households.

• Personal controls: Individual behaviors to protect themselves and those around them.
• Administrative controls: Processes and policies that keep people safe.
• Engineering controls: Physical structures put in place to distance people from hazards.  ...
