Information about dengue.
Dengue Hemorrhagic fever or H-fever commonly known here in the Philippines is a tropical disease caused by four dengue viruses and arbovirus. The three other arboviruses are Chikungunya, O’nyong-nyong and West Nile Fever. Dengue is transmitted by a vector which a female mosquito is called Aedes Egypti.
The incidence is more frequent during rainy season. Usually the breeding places of these mosquitoes are in water storages or standing water within the premises, commonly disseminated in schools and hospitals.
Sudden high fever (39-40 degree Celsius) lasting for 2-7 days, headache, flushed skin, nausea and vomiting, abdominal pain, petechiae are some manifestations of dengue. A simple test can be done to observe if there will be petechial rashes/hemorrhage. It is called Tourniquet Test done by occluding the arm veins for five minutes and examining the forearm for petechial hemorrhage/ capillary fragility. It is also better to have a platelet or blood exam.
“Prevention is better than cure.” Thus, let us avoid mosquito bites and have a clean environment. We can use mosquito repellents, mosquito nets and we can clean/drain the usual breeding places of mosquitoes. Dengue has different classification according to severity, if it became too sever (Grade IV) the mortality rate is high.
