Because of the COVID-19 pandemic, preparing for wildfires might be a little different this year. Know how wildfire smoke can affect you and your loved ones during the pandemic and what you can do to protect yourselves.

About Masks

COVID-19 spreads mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes, talks, or raises their voice (e.g., while shouting, chanting, or singing). To reduce the spread of COVID-19, CDC recommends that people wear masks in public settings when around people outside of their household, especially when other social distancing measures are difficult to maintain.

Tribal Communities

The United States federal government maintains a government-to-government relationship with federally recognized American Indian tribes and Alaska Native (AI/AN) entities. The "government-to-government" relationship is based in the U.S. Constitution, treaties, Federal statutes, court decisions, and Executive Branch policies, as well as moral and ethical considerations.

How CDC Determines the Level of a Destination's COVID-19 Travel Health Notice
CDC notifies travelers and other audiences about health threats in destinations around the world through Travel Health Notices (THN). During the COVID-19 pandemic, CDC has also provided an interactive world map specifically showing COVID-19 travel recommendations by destination. This world map uses an evidence-based approach, referred to as the COVID-19 THN Risk Assessment, to evaluate the COVID-19 risk in each destination.
