What Is Dengue Fever?
Dengue fever generally attacks the body’s immune decline. Actually when we are exposed to dengue infection, the body will produce immunity against the types of dengue virus, this immunity will last a lifetime. Unfortunately, dengue fever is caused by many strains or types of the virus so that even though we are immune to one type, but we can still suffer from dengue fever from other types of viruses.
Dengue hemorrhagic fever or dengue is dengue fever with a more severe degree. The main difference is in the dengue fever was not found in patients with bleeding manifestations. In the skin of patients with dengue fever, red rash just looking around while on dengue hemorrhagic fever patients will look the spots bleeding spots. In addition to bleeding in the skin, dengue haemorrhagic fever sufferers may also experience bleeding from the gums, nose, intestines and more. If not treated immediately, dengue haemorrhagic fever can cause death.
Which areas vulnerable dengue fever?
Contracted dengue fever in many tropical and subtropical regions. Asia ranks first in the number of dengue fever sufferers each year. This is probably due to rainfall in Asia, which is very high, especially in east Asia and south combined with environmental sanitation is not good.
WHO estimates more than 500,000 of 50 million cases of dengue fever requiring hospitalization. More than 40% of the world population living in endemic areas of dengue fever.
How can dengue fever transmission?
Dengue virus is transmitted through the bite of Aedes aegypti mosquito that previously bit an infected person dengue. This mosquito population will increase rapidly during the rainy season but the mosquito Aedes aegypti can live and breed in the tub of water reservoirs throughout the year. One bite of an infected mosquito is able to cause dengue disease in healthy people.
Transmission of dengue fever can not be directly from person to person but should be through an intermediary mosquito so we do not have to worry about direct contact with dengue fever patients.
What are the symptoms and signs of dengue fever?
After being bitten mosquitoes carrying the virus, the incubation period will last between 3 to 15 days until the symptoms of dengue fever appear. Symptoms of dengue fever will be preceded by a feeling of chills, headache, pain when moving eyes and back pain. Pain in limbs and joints will occur several hours after the symptoms of dengue fever began to be felt. Body temperature will rise rapidly to reach 40 degrees Celsius with a normal pulse and blood pressure tends to fall. The eyeball will appear reddish. Redness also appeared on the face that will quickly disappear. Glands in the neck and throat sometimes go bigger.
Fever and other symptoms of dengue fever will last for 2 days followed by a rapid drop in temperature accompanied by the increased sweat production. This temperature decrease period usually lasted a day, then the body temperature will rise again quickly. At present the entire body except the patient will be flushed in the face.
How does the handling of dengue fever patients?
Because dengue fever is caused by a virus, there is no specific treatment for this disease including the use of antibiotics. Treatment of dengue fever are generally intended to address only the symptoms (symptomatic). Rest and adequate fluid intake are two things that are important in dengue fever patients. The use of aspirin and NSAIDs should be avoided. The use of paracetamol, particularly to overcome the symptoms of fever and headache occur.
How the continuation of dengue patients?
Dengue fever will not cause death. Past experience, deaths from dengue fever less than 1% of all cases occur. Improving the condition of the patient will take several weeks.
What about dengue haemorrhagic fever?
Dengue hemorrhagic fever or DHF usually occurs in children under 10 years old. Symptoms include abdominal pain, bleeding, and shock. In the event of shock then often called Hemorrhagic Dengue Shock Syndrome or DSS. Patients with DSS are usually rather difficult to be restored.
Dengue fever begins with a high and a great headache. There are symptoms of respiratory and digestive tract of swallowing pain, cough, nausea, vomiting and abdominal pain. Shock can occur after 2 to 6 days since the symptoms of dengue appear. Symptoms begin with a decrease in shock temperature suddenly, akral cold, pulse weak, and bluish on the lips.
In DHF, there is bleeding into soft tissue, bleeding spots on the skin, vomiting blood, blood in the dirt, bleeding gums and nosebleeds. In some cases pneumonia can occur and inflammation of the lungs to the heart muscle, or myocarditis.
Patients with DHF must monitor closely, especially on the fourth day since the onset of symptoms. If there is bluish or cyanosis the patient should be given oxygen and when there is failure of vascular patients should be infused. Required blood transfusions to control bleeding.
The death rate is very high dengue patients between 3 to 30%. Most of the deaths occur in children.
How to prevent dengue fever?
Virus transmission by mosquitoes must be stopped to prevent dengue fever. To do this the dengue fever patients should be surrounded by mosquito net / mosquito net until the fever subsided.
Dengue fever prevention requires control or eradication of mosquitoes carrying the virus. Perform 3 M (Draining, Closing and Hoarding) where the preferred place for mosquitoes to breed. The role of government is needed as a motivator as well as performing the role of the community.
Until there is currently no vaccine for dengue fever fit, so the only prevention can be done periodically
