Inbound travelers to the United States now can use self-administered Covid-19 tests to satisfy the CDC's requirements for international visitors.

Updated May 10, 2021


The Centers for Disease Control and Prevention announced Friday that international travelers arriving in the United States may now use at-home Covid-19 tests to satisfy the agency's requirements for passengers.

Currently, visitors and returning residents must provide a negative test within three days of arrival or show proof of recovery from the coronavirus. The home test must be a SARS-CoV-2 viral test, either NAAT or antigen, both of which have received emergency-use authorization from the Food and Drug Administration. The testing procedure must include a telehealth service affiliated with the manufacturer of the test that provides real-time supervision remotely through an audio and video connection. Some FDA-authorized self-tests that include a telehealth service might require a prescription. The CDC's page on international travel has the full requirements.

Guidance from the CDC also now says fully vaccinated people do not need to wear a mask outdoors, except in crowded spaces and venues. Those who have not been vaccinated should continue to wear face coverings when outdoors, and everyone, regardless of vaccination status, should wear a well-fitted mask when engaging in indoor social activities in public settings.

The news comes shortly after the CDC announced that fully vaccinated people can travel within the U.S. without getting a Covid-19 test or having to quarantine. The agency, however, still recommends that vaccinated travelers wear a face mask that covers their mouth and nose, maintain six feet of distancing, avoid crowds, self monitor for symptoms, and wash their hands frequently or use hand sanitizer. The requirement that all international travelers entering the U.S. must show proof of a negative Covid-19 test prior to boarding remains in effect.

People are considered fully vaccinated at least two weeks after receiving the single dose of the Johnson & Johnson vaccine, or the second dose of the Pfizer or Moderna vaccines. The latest guidance, which says fully vaccinated travelers are less likely to get and spread Covid-19, could help accelerate the meetings industry's recovery.

The CDC currently advises planners to avoid organizing large gatherings when possible, consider the level of risk when deciding to host an in-person event, promote healthy behaviors among attendees and prepare for possible infections.

Detailed guidance on what to do before, during and after an event to ensure the highest levels of safety are outlined below. Planners can also consult the CDC's new Event Readiness Assessment checklist.

CDC Guidelines for Events


Meeting organizers preparing for shows scheduled in 2021 and beyond must consider the health and safety of attendees and staff at every step of the planning process. Guidance from the CDC provides a critical roadmap for resuming events in the U.S., with details on how to evaluate the risk levels and key actions that can help prevent the spread of the virus. Cleanliness protocols are also covered.

The CDC guidelines encourage event organizers to follow state and local regulations on gatherings (updates on Covid-19 restrictions in all 50 states can be found here). Meeting planners should continually monitor the outbreak and make adjustments to the event plan as needed.

"Event planners should work with state and local health officials to implement this guidance, adjusting to meet the unique needs and circumstances of the local community," reads the document. According to the CDC, "this guidance is meant to supplement — not replace — any state, local, territorial, or tribal health and safety laws, rules, and regulations with which gatherings must comply."

The following is extrapolated from the CDC recommendations.

Risk Factors to Consider

  • The number of Covid-19 cases within the community: High or increasing levels of local infection could increase the risk of spread among attendees.
  • Potential for exposure during travel: Airports, airplanes, bus stations, buses, train stations, trains and public transport are all places where physical distancing might be challenging and ventilation could be poor.
  • Length of the event: Longer meetings pose greater risk. Being within six feet of someone who has Covid-19 for a total of 15 minutes or more (over a 24-hour period) greatly increases the risk of becoming infected.
  • The setting: Indoor events, especially in places with poor ventilation, pose more risk than outdoor events.
  • Number of people attending: The more people there are at an event, the greater the likelihood for exposure. Planners must also consider crowding, and should implement modified room layouts or block off seats to ensure social distancing.
  • Behavior or attendees: Events where people do not maintain physical distancing and/or do not wear a mask correctly can increase the risk of contagion.


For meetings that are scheduled to go on, the CDC has offered the following recommendations:

Before the Event

  • Educate staff members and attendees as to when they should stay home.
  • Establish flexible refund policies for anyone who falls ill, must care for a sick household member or is at high risk of contracting Covid-19 and can no longer attend the event.
  • Gather supplies such as soap, hand sanitizers that contain at least 60 percent alcohol, tissues, disinfectant wipes, no-touch trash cans and face masks that will be distributed on-site. Make sure both attendees and staff members will have access to the supplies. Staff members should be required to wear face masks and attendees should be encouraged to wear them as well.
  • Meet with the venue's emergency operations coordinator or planning team. Discuss their emergency protocol and develop a contingency plan that addresses various coronavirus-related scenarios that could affect the meeting.
  • Designate a person or office to be responsible for Covid-19 concerns. Ensure all employees and guests know who this person is and how to contact them.
  • Encourage the event staff and all attendees to practice good personal health habits each day. Be sure to share resource materials from reputable sources on symptoms, prevention and more.
  • Modify the event layout for social distancing. This includes limiting attendance or reducing seating capacities. Multiple entrances and exits should also be offered and event organizers should consider staggering the use of shared indoor spaces, such as dining halls and lounges.
  • Prioritize outdoor activities where social distancing can be maintained.
  • Offer online options in addition to in-person attendance to help reduce the number of guests on-site.
  • Plan for employee absences. Event organizers should adopt flexible attendance and sick-leave policies that encourage staff members who are ill or caring for someone else who is ill to stay home. In addition, alternatives may need to be developed for those who are at high risk for contracting the virus. Staff members should be cross-trained to accommodate any changes that may arise.
  • Discourage anyone who is sick from attending the meeting and request that people who begin displaying any Covid-19 symptoms leave immediately.
  • Create a quarantine zone for anyone who may fall ill. Work with the local health department and hospital to create a plan for treating staff members and participants who do not live nearby and may need to be quarantined for some time. Consider drafting a plan for how vulnerable populations will be separated and cared for if need be.
  • Aim to limit staff contact on-site. Develop a staggered shift schedule to reduce the risk of exposure and allow staff members to telecommute if they are not needed at the venue.
  • Work with local health officials and develop a plan in case the situation changes and the meeting must be cancelled or postponed. Develop specific criteria for postponing or cancelling and outline what the refund or re-ticket policy will be. Assess whether the event could be held virtually if necessary.
  • Consider limiting event attendance to guests and staff who live in the local area to reduce the risk of spreading coronavirus from areas that have high levels of transmission.
  • Identify automated platforms that can be used to quickly disseminate updates to staff members and attendees via text message, email and more. Take care to consider any potential language, cultural or disability barriers that may affect communication.

During the Event

  • Stay informed and closely follow all coronavirus-related news and updates. Pay particular attention to developments in the local area.
  • Share frequent updates with employees, participants, partners and more. Promote preventive resources and address any concerns.
  • Stagger and limit attendance times to reduce the number of guests in the venue at one time.
  • Conduct daily temperature screenings and/or health checks of employees and guests.
  • Maintain a healthy stockpile of prevention supplies such as hand sanitizer, soap and face masks. Frequently touched surfaces and objects should be cleaned on a regular basis with detergent and water prior to disinfection. Develop a schedule for increased routine cleaning and disinfection.
  • Post signs in highly visible locations such as the entrances and restrooms that encourage protective measures. Broadcast regular announcements on reducing the spread of Covid-19 on public address systems, and share messages on social media.
  • Develop signs and messaging in alternative formats for those who are blind/have limited vision, or are deaf/hard of hearing. This includes messages in large print, braille and American Sign Language.
  • Limit the number of people who can use a restroom at one time and post signs or markers outside the restroom to prevent crowds from forming. Consider adding barriers between bathroom sinks.
  • Avoid offering any self-serve food or drink options such as buffets and salad bars. Use disposable dishes and utensils and offer prepackaged foods or individually plated meals. Add floor markers to ensure attendees stay six feet apart while waiting in line to order or pick up food.
  • Ensure ventilation systems operate properly and increase circulation of outdoor air as much as possible by opening windows and doors when feasible.
  • Separate anyone who is sick from the rest of the group. Place them in a quarantine zone and give them clean, disposable face masks. Work with the local hospital and health department to provide appropriate care. Discourage infected individuals from taking public transportation, shared rides and taxis.

After the Event

  • Hold a post-event meeting with the venue’s emergency operations coordinator or planning team to discuss lessons learned. Ask participants, partners and staff to share additional feedback.
  • Look for new agencies and partners who can help improve future plans.
  • Continue to monitor emergency preparedness resources and training.

Cleanliness Guidelines


Cleaning and disinfection can help reduce the risk of exposure to Covid-19 and are key to reopening public spaces, according to the CDC. The organization has issued reopening guidelines for how to properly clean public spaces, including what the appropriate disinfectants are and how frequently surfaces should be cleaned. The guidelines can be viewed in full here.
