Airports in multiple countries have begun rolling out COVID-style health measures after a deadly virus outbreak raised concerns among global health officials, reviving memories of early pandemic travel restrictions.

The response follows warnings from international health authorities that the virus, which currently has no approved cure or vaccine, has shown signs of spreading across borders through international travel. Officials say early detection and containment at transit hubs is now critical, according to guidance shared by the World Health Organization’s emergency monitoring team.

Several major airports have reintroduced temperature screening, health questionnaires, and targeted passenger monitoring, particularly for travelers arriving from regions reporting confirmed cases. Some terminals have also increased the use of isolation rooms and on-site medical staff, similar to protocols used during the height of COVID-19.
