Dengue is a mosquito-borne infection that has become an international public health concern.
A senior official of the health department told: "Doctors are asking people to wear full-sleeved clothes and also use mosquito repellents."
According to the WHO, the dengue virus is transmitted to humans through the female of Aedes mosquitoes.
Dengue fever is a severe, flu-like illness that affects infants, young children and adults, but seldom causes death. The clinical features vary according to the age of the patient. Infants and young children may have a non-specific febrile illness with rash.
The illness commonly begins with a sudden rise in temperature accompanied by facial flush.
