The Centers for Disease Control and Prevention (CDC) says the following countries of South Asia, or the Indian subcontinent are reporting higher-than-usual numbers of dengue cases, and travelers visiting these countries may be at increased risk: India, Pakistan, Bangladesh and Sri Lanka.
Because dengue is spread by mosquito bites, all travelers to risk 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.
Health effects from dengue include fever, headache, nausea, vomiting, rash, muscle and joint pain, and minor bleeding.
Dengue can become severe within a few hours. Severe dengue is a medical emergency, usually requiring hospitalization.
In severe cases, health effects can include hemorrhage (uncontrolled bleeding), shock (seriously low blood pressure), organ failure, and death.
