(Vax Before Travel)
The US CDC issued a Watch – Level 1, Practice Usual Precautions, travel advisory on February 23, 2022, confirming that countries in parts of Asia and the Pacific Islands are reporting increased dengue cases this year.
And travelers visiting these countries may be at increased risk:
- Sri Lanka
- Timor-Leste (East Timor)
San Juan, Puerto Rico, recently confirmed additional dengue cases in 2022.
Because mosquito bites spread dengue, all travelers to risky areas should prevent mosquito bites by using an EPA-registered insect repellent, wearing long-sleeved shirts and long pants when outdoors, and sleeping in an air-conditioned room or room with window screens or under an insecticide-treated bed net.
Dengue is a disease caused by a virus spread through mosquito bites.
The disease can take up to 2 weeks to develop, with illness generally lasting less than a week. However, dengue can become severe within a few hours, usually requiring hospitalization.
Health effects can include hemorrhage, shock, organ failure, and death in severe cases.
The US FDA authorized the Dengvaxia vaccine for limited use on May 1, 2019, for people with laboratory-confirmed previous dengue infection and living in endemic areas.
Dengvaxia is not approved for use in individuals not previously infected by any of the dengue virus four serotypes or for whom their immunization information is unknown.
