Dengue Virus

ISLAMABAD: Dengue cases in Pakistan exceed 50,000. In the past 24 hours 229 people have been diagnosed with the dangerous virus primarily carried by female mosquitoes, ARY News reported on Sunday.

Dengue fever yesterday claimed two more lives in Karachi, taking the death toll from the mosquito-borne disease to 37, this year so far.

The deceased were identified as Shehzad, 40-year old, resident of Korangi and Abdul Rafay, 60, resident of Shah Faisal Colony. Both were undergoing treatment at a private hospital of Karachi where they breathed their last, today.

With the recent deaths, the tally has jumped to 37 this year so far, while the number of dengue patients in Sindh has soared to 14,317.

Earlier on November 12, a three-year-old boy and 32-year-old Nadir had also succumbed to dengue fever in the metropolitan.

Sindh Governor Imran Ismail had inaugurated an anti-dengue campaign in Karachi on Monday where he had announced the establishment of camps to conduct free blood tests of the citizens.

While inaugurating the campaign, Governor Ismail had announced that anti-dengue spray would be made across the metropolis while camps were being established to conduct free dengue test which costs at least Rs1600 in laboratories.

He had said that companies were stepping forward to invest in Pakistan. Ismail had said that the citizens had been facilitated to undergo free blood tests for dengue disease.

Dengue infections are caused by four closely related viruses named DEN-1, DEN-2, DEN-3, and DEN-4. These four viruses are called serotypes because each has different interactions with the antibodies in human blood serum.
Native Dengue Virus Type 2 is a preparation of viral particles concentrated from tissue culture supernatant. … It is a mosquito borne viral infection that may be asymptomatic or may cause undifferentiated fever, dengue fever, dengue haemorrhagic fever or dengue shock syndrome.The four dengue viruses (DENV) represent the most common human arbovirus infections in the world and are currently a challenging problem, particularly in the tropical and subtropical regions of Asia and the Americas.
Some develop dengue hemorrhagic fever after the initial fever declines — a more severe form of the illness that can cause organ damage, severe bleeding, dehydration and even death. But with early treatment, the mortality rate for all dengue fever is currently fewer than 1 of 100 people.Papaya Leaves: One of the traditional and effective medicine which helps to recover from Dengue is the juice of papaya leaves. 2 tablespoon papaya leaf juices are suggested by the doctors. The diet should also contain green leafy vegetables for better recovery.There is unfortunately no vaccine or cure for dengue fever, so if you think you have it, rest, drink plenty of fluids, and take a pain reliever with acetaminophen. Don’t take aspirin. If you feel worse after the first 24 hours, make sure you get treatment.
Dengue and Dengue Hemorrhagic Fever
There are four dengue virus serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. They belong to the genus Flavivirus, family Flaviviridae (of which yellow fever virus is the type species), which contains approximately 53 viruses.

Dengue Viruses and Dengue Disease

DENV-1 through DENV-4 are members of the Flavivirus group of the virus family Flaviviridae. The flavivirus genome consists of approximately RNA 11,000 base pairs (bp), which translate into three structural and seven nonstructural proteins (see “Chimeric Virus Vaccines” later). The four distinct DENVs all evolved from a common sylvatic ancestor, with separate introductions into the urban cycle of transmission
