affects infants, young children and adults. DF is rarely fatal.
Dengue hemorrhagic fever (DHF): DHF is a complication of the disease that can be fatal. It
usually occurs if you have dengue infection more than once. The symptoms of DHF are similar
to DF but the condition of the patient show rapid deterioration 2-5 days after the fever starts. Ifthe disease is not severe, the signs and symptoms decrease after the fever resolves. Patients with
severe disease can unexpectedly deteriorate after a few days of fever and develop bleeding fromthe nose, gums, mouth or in the skin, which leads to purplish bruises. In some of these patients

This year, Punjab has seen alarming rate of Dengue cases. Overall 4,000 people have been
affected, each day at least 100 new case is registered in the Province. Almost all Dengue casesare being reported in the cultural capital almost every day. The government has once again
appealed to the world leaders for helping them eradicate the disease. Sri Lanka was the first
country to step in, the Sri Lankan government has been assisting Pakistans fight against dengue
virus, by sending 11 expert doctors to the country. Foreigners are also affected in the province,mainly Chinese engineers. In the federal capital city of Islamabad, 32 cases have been reported
while one person has died due to the dengue outbreak. Fresh monsoon rainfalls are also likely
(September 14 night) in the province that could deteriorate the situation if the authorities fail toact in time.
Dengue may not remain confined to just northern Pakistan, but it could affect the rain-hit people
of Sindh too, though reports have started coming that dengue has started in Sindh as well.
Overall 270 people have died in Sindh due to extremely heavy downpour creating large stagnant
ponds, an ideal place for mosquito breeding.
The virus is coveyed from humans to the mosquitoes and back to humans.
