primary, secondary and presumptive dengue infection, respectively. DEN-3 was the predominant serotype. The deceased suffered from unconsciousness, tachycardia, tachyreu, decreased capillary refill, decreased body temperature, hypertension, and oliguna,
Symptoms usually develop within 3-14 days after being exposed to the dengue virus (also known as incubation period). The average incubation period is around 4-7 days. Symptoms of dengue are: 1. Sudden-onset fever 2. Headache (typically located behind the eyes) 3. Muscle and joint pain 4. Rash 5. Chills (shivering) 6. Facial flushing 7. Loss of appetite 8. Sore throat 9. Abnormal bleeding such as nosebleeds, bleeding gums and/or blood in your urine.
Dengue virus is an RNA virus. Transmission of this virus occurs in a cycle. An infected human is bitten by a female mosquito. The infected mosquito then bites another human, and the cycle continues. MOSQUITO Aedes aegypti mosquitoes most commonly bite at dusk and dawn, indoors, in shady areas, or when the weather is cloudy. They can bite and spread infection at any time of day and all year long. The mosquitoes prefer to breed in areas of stagnant water, such as flower vases, uncovered barrels, buckets, water coolers and discarded tires. Some of the dangerous areas are wet floors and toilet tanks, as they allow the mosquitoes to breed in the residence. Although the lifespan of an adult A. aegyptiis two to four weeks depending on conditions, the eggs can be viable for over a year in dry state. This allows the mosquito to reappear after a cold winter or dry spell. There are four serotypes of the virus that cause dengue (DEN-1, DEN-2, DEN-3 and DEN-4) Some facts about Ades mosquito- 1....
A probable diagnosis is based on occurrence of fever along with some of the following symptoms. 1. Nausea and vomiting 2. Rash 3. Generalized pain The diagnosis also takes into account whether the suspected person lives in endemic (high prevalence) area. Blood test– 1. Microscopic examination: This is done in order to detect dengue. The earliest change detectable is a low white blood cell count which may then be followed by low platelets and metabolic acidosis. 2. Haematocrit-Haemoconcentration, as estimated by an increase in haematocrit of 20% or more compared with convalescent values, is suggestive of hypovolaemia due to vascular permeability and plasma leakage. Virus isolation– Cell culture is the most widely used method for dengue virus isolation Nucleic acid detection– Reverse transcriptase-polymerase chain reaction (RT-PCR) assays offer better sensitivity compared to virus isolation. Dengue virus (Nucleic acid)can be detected in the blood about first 5 days after onset of symp...
There is no specific medication for treatment of a dengue infection. Persons suspected of dengue can use analgesics (pain relievers) and avoid those containing aspirin.They should take plenty of fluids, rest and consult a physician at the earliest possible. If condition does not improve after 3-5 days, then one should seek further medical advice.
A person with dengue may develop a severe and life threatening form of dengue known as dengue shock syndrome. This may be accompanied by a sudden and severe drop in blood pressure. Other symptoms of dengue shock syndrome are as follows: 1. Cold, clammy skin 2. A weak rapid pulse 3. Dry mouth 4. Reduced flow of urine 5. Fast breathing The patients may seek medical advice immediately.Use insect repellents and mosquito nets to avoid being bitten.

- Patients and Methods
Dengue is the most widely distributed mosquito-borne viral infection of humans, affecting an estimated 100 million people worldwide each year. It is endemic in parts of Asia and the Americas and has been increasingly reported from many tropical countries in recent years [1–3]. Dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) are among the leading causes of pediatric hospitalization in Asia, with up to 500,000 cases reported annually to the World Health Organization (WHO) . Mortality rates from <1% to 5% are usually quoted for DHF/DSS from centers experienced in fluid resuscitation [4, 5], but rates up to 44% have occasionally been reported with regard to established shock [6, 7]. There are 4 serotypes of dengue virus, all of which may produce either a nonspecific febrile illness, dengue fever (DF) or may result in the more severe manifestation of DHF. The pathophysiology of DHF is not clear, but the main feature differentiating it from DF is an increase in vascular...
Study design.The study was a randomized, double-blind trial comparing the efficacy of 4 different fluid regimens in the initial management of DSS in children. The 4 solutions were dextran 70 (Onkovertin 70), 3% gelatin (Gelafundin), lactated Ringer's, and “normal” saline (all fluids were supplied by B. Braun). The study took place from September 1996 through September 1997 on the ICU of Dong Nai Paediatric Hospital, a specialist children's hospital situated 40 km from Ho Chi Minh City, in southern Vietnam. The ICU has 15 beds, staffed by an average of 5 nurses and 3 doctors at any time. There are no facilities for ventilation, and invasive monitoring is carried out only in exceptional circumstances. Patients.Children aged from 1 to 15 years who presented to the hospital with clinically diagnosed DHF grade III or IV were eligible for enrollment in the study, provided they had not received any iv fluid therapy and a parent or guardian gave informed consent. Those with severe hemorrhag...
A total of 230 patients were recruited into the study over 1 year; 222 of these had DHF grade III and the remaining 8 had DHF grade IV. Of the 230 patients, 205 (89%) had serologically confirmed dengue, and 10 (4%) had findings suggestive of dengue (significant elevation of dengue IgG level in a single acute sample, but without a diagnostic level of dengue IgM). Samples from the remaining 15 children were inadequate for analysis. In view of the small number of children with DHF grade IV who received treatment with a different regimen, we focused this report on the 222 children with DHF grade III. All of the patients presenting with grade IV DHF made a good recovery without serious complications. Demographic information, clinical features at presentation, and preliminary laboratory data for all children with DHF grade III are shown in table 2. The numbers of children in each group were similar, with similar proportions of males and females. Children presenting with shock earlier in t...
In this study we found the most significant factor predicting the clinical response to resuscitation in DSS was the width of the pulse pressure at presentation. Children with a pulse pressure of ⩽10 mm Hg on admission were more likely to have prolonged shock and to experience subsequent episodes of shock than were those presenting with higher pulse pressures. The preliminary analysis suggested a difference in outcome related to the fluid treatment group, but despite blinding and randomization, there were differences in severity between the treatment groups. Of all the fluids, Ringer's lactate performed the least well. For children receiving this fluid, recovery times were longer, initial therapy was more likely to be considered a failure, and dextran was more likely to be required for treatment of the initial episode of shock than for children in the other three groups. The greater number of children with profound shock in the group may explain this. Conventionally, the cutoff for a...
We are very grateful to the director and staff of the Dong Nai Paediatric Hospital for help and support during the study. All fluids were kindly provided by B. Braun. In addition, we are most grateful to Dr. M. J. Cardosa and the staff of the Institute of Health and Community Medicine, Universiti Malaysia, Sarawak, Malaysia, and to Dr. T. Endy and the staff of the Department of Virology, Armed Forces Research Institute of Medical Sciences, Bangkok, Thailand, for their help with serological confirmation of dengue infection. Finally, we would like to pay tribute to Dr. Cao Xuan Thanh Phuong, who died tragically in October after a short illness. Her hard work, energy, and enthusiasm will be greatly missed by all of her friends and colleagues.

Early shock (also known as compensated or normotensive shock) is characterized by narrowing pulse pressure (systolic minus diastolic BP approaching 20 mmHg), increasing heart rate, and delayed capillary refill or cool extremities. ✓ DO administer colloids (such as albumin) for refractory shock.
