The Department of Health initiated the National Dengue Prevention and Control Program since 1993.They are aiming for reducing morbidity and mortality from dengue infection by preventing the transmission of the virus from the mosquito vector human. In line with this their mission is to improve the quality of health of Filipinos by adopting an integrated dengue control approach in the prevention and control of dengue infection.
According to them there are 62,503 cases of the mosquito-borne illness have been reported in the Philippines from January 1 to August 21, up nearly 90 percent from the same period last 2010. The death toll was also up from 350 in the same period 2010. The department said the number of dengue cases in the country started to rise in May and peaked last month at the onset of the rainy season. Disease experts are now closely monitoring several barangays across the country for cases of dengue outbreak. In line with this, the group decided to conduct a class and project regarding the prevention and control of dengue fever to raise the awareness of the residents of Barangay Macapagal Village Zone 3.
II.CONTENT OF THE TOPIC TO BE DISCUSSED
What is Dengue?
Dengue fever is an acute febrile disease caused by infection one of the serotypes of dengue virus which is transmitted by genus Aedes. It refers to a benign form of disease with systematic symptoms, fever and often rash associated with pain behind the eyes, the joints, and the bones. Dengue hemorrhagic fever is a severe, sometimes fatal manifestation of dengue virus infection characterized by a bleeding diathesis and hypovolemic shock. Etiologic agent and vector
Dengue viruses (DEN) types 1, 2, 3, 4, which are classified as flaviviridae, are principally transmitted from human to human through the bites of the Aedes aegypti mosquitoes. The female mosquito bites the infected human during the day and can transmit the virus to another host immediately or after 8 to 10 days of incubation within the salivary gland of the mosquito. The mosquito host remains infected for life.
Mode of Transmission
By bite of an infected mosquito, principally the Aedes Egypti – is a day biting mosquito (they appear two hours after sunrise and two hours before sunset ). It breeds on stagnant water. It has a limited and low flying movement. It has fine white dots at the base of the wings; with white bands on the legs.
Aedes albopictus may contribute to transmission of dengue virus in rural areas. And other contributory mosquitoes are the Aedes polynensis and Aedes scutellaris simplex.
After an individual is bitten by an infective mosquito, the virus undergoes an incubation period of 3 to 14 days.
Signs and symptoms of dengue fever vary, depending on the form and severity of the disease. Dengue fever
With the mild form of the disease, you may experience some or all of these signs and symptoms: ← High fever, up to 105 F (40.6 C)
← A rash over most of your body, which may subside after a couple of days and then reappear ← Severe headache, backache or both
← Pain behind your eyes
← Severe joint and muscle pain
← Nausea and vomiting
Sign and symptoms usually begin about four to seven days after being bitten by a mosquito carrying a dengue virus. Mild dengue fever rarely causes death, and your symptoms will usually subside within a week after starting.
Dengue hemorrhagic fever
More-severe forms of the disease usually begin the same way as the mild form (dengue fever) then become worse after several days. Dengue hemorrhagic fever a more severe form of the disease than initial dengue fever can cause...
