Measles, a highly contagious airborne viral disease, is resurging globally and poses serious risks to vulnerable populations such as children, the elderly, immunocompromised individuals, and travelers. Because the virus can linger in enclosed spaces like buses, planes, and trains, travelers are at heightened risk, especially during outbreaks.
Experts Dr. Monica Gandhi (UCSF) and Dr. David Cutler (Providence Saint John’s Health Center) emphasize that vaccination is the most effective prevention tool. The MMR (measles, mumps, rubella) vaccine offers long-term immunity after two doses. Infants aged 6–11 months should get an early dose before travel, while unvaccinated teens and adults should receive two doses 28 days apart. Travelers should carry proof of vaccination and ideally receive it at least two weeks before departure.
Additional protective measures include:
i. Wearing N95 or KN95 masks in enclosed or crowded places.
ii. Practicing hand hygiene and avoiding face-touching.
iii. Ensuring ventilation, such as sitting near open windows on buses or trains.
If exposed, people should monitor for symptoms like fever, rash, and red eyes (usually appearing 7–14 days after exposure), isolate immediately, wear a mask, and seek medical attention. Supportive treatment includes rest, fluids, and fever management. In some cases, Vitamin A supplements can reduce severity. Post-exposure strategies include vaccination within 72 hours or administration of immune globulin for high-risk individuals (e.g., infants, pregnant women).
Beyond the acute phase, measles can cause long-term complications, including:
i. Immune amnesia, weakening the body’s defense against other infections.
ii. Neurological issues, such as encephalitis.
iii. Respiratory complications and possible fertility problems.
Health experts stress vigilance, early protection, and responsible travel practices to curb further spread.
