Summary of Testing Considerations for Asymptomatic Travelers

Primary goals of testing: Reduce risk of SARS-CoV-2 transmission during travel and at destination; reduce period of quarantine after arrival at destination; a negative test result may be required for entry to a country or locality.

Pretest probability of infection: Low–moderate

Testing strategy:

• Test within 1–3 days of departure.

• May test upon arrival, then 3–5 days after arrival AND quarantine for 7 days at destination, even if test negative.

• If no testing upon arrival, quarantine for 10 days.

Positive result: If test positive before departure, delay travel and self-isolate. If test positive at destination, self-isolate until local criteria for release from isolation are met.

Negative result: If test negative before departure, follow standard infection prevention measures (eg, masking, physical distancing). If test negative after arrival, quarantine for period specified by destination rules (ie, 7 days) and follow standard infection prevention measures (eg, masking, physical distancing).
