PURPOSE OF REVIEW: The current article will review how the coronavirus disease 2019 pandemic has changed travel and travel medicine. RECENT FINDINGS: Travelers spread severe acute respiratory syndrome coronavirus 2 globally and continue to spread variants. The characteristics of the virus, the place, and time created a perfect storm that allowed the virus to quickly spread globally. The virus spread by every mode of travel with risk of transmission influenced by proximity to an infected person, duration of trip, physical characteristics of the space, and ventilation. Superspreading events were common; a small percentage of infected people accounted for most of transmission. The travel and tourist industry was devastated as lockdowns and quarantines severely restricted domestic and international travel. A trip includes multiple segments and shared sequential spaces, mostly indoors. Creating safe travel requires attention to all segments of a trip. SUMMARY: The coronavirus disease 2019 pandemic has affected every part of travel and travel medicine. The rapid development of multiple safe and effective vaccines and their deployment is allowing resumption of travel, yet many populations lack access to vaccines, and high levels of transmission continue in many areas. Providing documentation of vaccination or immunity in a consistent, verifiable, interoperable system is one of many active issues.
