Everyday Activities
As you gather in person with others for leisure activities, travel, chores, work, and education, there are easy precautions you can take to significantly lessen your exposure to COVID-19 and keep from spreading it to others.
Indoors with People of Unknown Vaccination and Health Status
It is important to observe the individual masking guidelines and requirements of the places you visit. Note that masking is required in hospitals, clinics, and other health care settings to ensure patient safety. Many stores, airports, and other high-traffic locations also require or request masking. Others do not. For your protection, wearing a well-fitting mask is strongly recommended in the following indoors settings:
- public transportation
- stores
- schools
- workplaces
- social gatherings
- gyms
- restaurants
- bars
- movie theatres
- museums
- wherever you are in close contact with people whose vaccination and health status you do not know


Mega Events: Indoors and Outdoors
Mega events are defined as events that attract crowds of greater than 1,000 indoors and greater than 10,000 outdoors. These large crowds pose a risk of substantial and severe COVID-19 outbreak. We strongly recommend wearing a mask when you attend such occasions, including concerts and sporting events.

Travel and Destination Guidelines
Before You Travel
It’s smart to consider your destination and activities in terms of possible exposure to COVID-19, even when traveling domestically. We recommend wearing masks on public transportation and inside transportation hubs. Visit the CDC website for more recommendations on domestic travel.

If you are traveling internationally, you can see which countries have the highest risk for COVID-19 on the CDC COVID-19 Travel Recommendations by Destination map.
While You’re There
When you travel to a foreign country, you must follow the rules of that country. If you test positive for COVID-19 while abroad, the rules of that country might require isolation in a hotel or hospital. If you are traveling with family members or a group, plan for what will happen if one person tests positive and others do not. Many travel insurance companies offer policies that cover the costs of isolation periods and COVID-19 treatments in other countries.
Flying into the United States
Requirements for travelers returning to the United States are subject to change. Before you enter the country, be sure to review the CDC Travel Requirements.
