Health Department Officials in Ho Chi Minh City warned Monday that more people in the city are contracting dengue fever.
Dengue fever is the most important viral disease transmitted by mosquitoes. According to health experts, the fatality rate is about 5%, with the highest risk posed to the elderly and those below fifteen.
Around 250 dengue cases have been hospitalized every week for diagnosis. The number of infected cases has reached 6,000 since early 2006.
Places where no proactive measures are taken are considered likely outbreak areas, including parts of Thu Duc, Binh Chanh and Binh Tan Districts.
Dengue mosquitoes hunt during daytime hours in contrast with their malarial associates that strike in the evening. Specialists say dengue is characterized by a sudden onset of symptoms.
These symptoms include high fever, severe headaches, extreme joint and muscle pain, nausea and vomiting. A rash may also appear three or four days after the fever begins.
Dengue fever may last 10 days but it takes from two to four weeks to recover completely.
As well, there is no cure. Rest and fluid replacement are normally the treatments suggested. Dengue fever is diagnosed by blood test.
