Jakarta, Dengue hemorrhagic fever (DHF) are caused by viruses that mosquitoes carry. When infected, the body will make antibodies to fight it. But can those who have been exposed to dengue fever again?
"If it's got all he has not been immune to dengue fever, because there are four types of dengue virus is DEN-1, 2, 3 and 4. So we can get dengue four times," said Dr. Leonard Nainggolan, SpPD-KPTI Pocari Sweat conference event 2012 'People's Education on The Importance of Fluids and Maintain Ion for Everyday Health' at Hotel Le Meridien, Jakarta, Sunday (02/12/2012).
Dr Leonard said that though it was hit four times by dengue virus different, but no one can guarantee absolute security that he will not be affected by dengue again. This is because the DEN-1 virus Indonesia for example with different Cuban DEN-1, so that the antibodies are also different.
"Now that transportation was very great, so I can not get the make sure sterile or free of dengue, especially when he went abroad. But chances are taxable laginya much smaller, because antibodies to the four viruses that already exist," said Dr. Leonard is an expert handling dengue fever and tropical infectious diseases of the faculty of medicine.
When a person suspected of dengue hemorrhagic fever?
Based on the WHO and the Ministry of Health, a person suspected of DHF if he had:
A. Sudden onset of fever plus two of the following symptoms
2. Headache
3. Pain behind the eyes
4. Muscle pain
5. Bone pain
6. Rash (red spots) on skin
7. Signs of bleeding
8. Leukocytes, or low white blood cell
9. Positive dengue serology test
10. There are neighbors with positive dengue
"Sudden onset of fever this morning for example it still looks fine, suddenly develop a fever the next day. Moreover, if the fever is accompanied by many symptoms," said the doctor was born abstainer Siantar, February 15, 1969.
While the bleeding that appears to only occur under the skin (red spots appear) until vomiting blood or bleeding, depending on how much fluid out of blood vessels from leaking.
"For the diagnosis of DHF can be done by testing IgG / IgM and NS1 testing. If asked which is the most accurate, the answer is both, but the timing is to be seen. If new fever 2 days then test NS1, but if the fifth day of fever test IgG / IgM, "he said.
This is due to test IgG / IgM antibody detection function is formed in the body. These new antibodies are formed after the third day of fever and new tools to detect on the fifth day when the number of antibodies have reached a certain figure.
While NS1 test used to detect the virus in the body is there or not, this test can be done since the first day of fever. Because it must be seen first time, how many days feeling feverish.
Phase of dengue fever have an incubation period of about 5-9 days from infection until symptoms develop, then the acute phase of which had onset of symptoms about 1-3 days and on days 4-6 is a critical phase. That's when the capillaries leak.
If the DHF patients experiencing emergencies such as shock, seizures, decreased consciousness and bleeding it must be admitted to hospital. But if you can still eat and drink well and there were no ambulatory emergency it can while still drinking a lot, a drug to treat the symptoms and laboratory tests to monitor hemoglobin, hematocrit, leukocytes and platelets.
"Because there is no vaccine or drugs to kill the virus, the environment and behavior pengandalian importantly, one of them by preventing standing water, especially during the rainy season, because just one drop of standing water can become breeding grounds for mosquitoes," said Dr. Leonard is also a consultant team dengue expert Strathmore University.
