What is the current situation?
Recently, there has been a large increase in the number of dengue cases in Vietnam, according to a World Health Organization (WHO) report. As of August 2017, more than 80,000 cases have been reported. Although most cases have been reported in the south, there has been a sharp increase in cases in the north, especially in Hanoi.
Dengue is spread through mosquito bites and can cause symptoms such as fever, headache, nausea, vomiting, rash, and pain in the eyes, joints, and muscles.
What can travelers do to prevent dengue?
Because mosquitoes transmit dengue to people, travelers to Vietnam should protect themselves against mosquito bites to avoid getting the illness. There is no vaccine or medicine currently available in the United States to prevent or treat dengue.
