More deaths due to dengue fever, people should not be subjective with the epidemic

On August 16, the Dak Lak Provincial Center for Disease Control announced that it had just recorded a death due to dengue fever in Buon Ma Thuot City. This is the first death due to dengue fever in Dak Lak since the beginning of the year.

Since the end of July, in Dak Lak province, dengue fever has increased rapidly with many outbreaks and "hot spots" of the disease. Recently, the Dak Lak Provincial People's Committee has also issued a document requesting departments, branches, sectors, organizations, and People's Committees of districts, towns, and cities to strengthen the implementation of activities to prevent and control dengue fever.

There have been consecutive deaths due to dengue fever.

The Provincial People's Committee assigned relevant units to urgently organize and implement an environmental sanitation campaign, thoroughly handle high-risk water containers, and eliminate mosquito larvae and pupae at all agencies, units and households in the area.

Health centers strengthen monitoring to detect patients early in the community, thoroughly handle detected cases and outbreaks of dengue fever; organize chemical spraying in 100% of households in the outbreak area to ensure proper techniques and monitor and evaluate vector indicators before and after spraying chemicals...

According to statistics from the Provincial Center for Disease Control, from the beginning of 2024 to August 15, the whole province recorded 1,453 cases of dengue fever.

In Hai Phong, according to information from the Hai Phong Department of Health, at around 4:00 p.m. on August 8, 2024, Le Chan District Medical Center received information from the Hai Phong CDC reporting a case of a patient named Bui THH, born in 1979, who died at his home in Thien Loi, Le Chan District with a diagnosis of Dengue shock - severe pneumonia, secondary infection, and multiple organ failure.

In Hanoi, last July, the Tropical Disease Center, Bach Mai Hospital continuously received severe cases of dengue fever, with complicated developments, many warning signs and dangerous complications, and a high risk of death.

According to Associate Professor, Dr. Do Duy Cuong, Director of the Center for Tropical Diseases, last July, the Center received dozens of cases of dengue fever with warning signs and were hospitalized.

The difference this year is that in suburban areas such as Hoai Duc, Dan Phuong, Phuc Tho, ... and provinces such as Hai Phong, Hai Duong, Thai Binh, ... dengue fever cases seem to occur earlier and more severely than every year.

A typical example is a 25-year-old male patient from Hoang Mai, Hanoi, who had a fever for 5 days and was hospitalized and tested positive for Dengue fever. During treatment, the patient developed severe liver failure, rapid platelet drop, and blood thickening.

According to Associate Professor Cuong, Dengue hemorrhagic fever is an infectious disease caused by the Dengue virus. The characteristics of Dengue hemorrhagic fever are fever, bleeding and plasma leakage, which can lead to hypovolemic shock, blood clotting disorders, organ failure, and if not diagnosed early and treated promptly, can easily lead to death.

There are four types of dengue virus: DEN-1, DEN-2, DEN-3 and DEN-4. The virus is transmitted from infected people to healthy people through mosquito bites. The Aedes aegypti mosquito is the main vector. The disease occurs in both children and adults, occurs year-round, and often increases during the rainy season.

Dengue fever has diverse clinical manifestations, progressing rapidly from mild to severe. The disease usually starts suddenly and progresses through three stages: febrile stage, critical stage and recovery stage.

Early detection of the disease and understanding the clinical problems in each stage of the disease helps in early diagnosis, correct and timely treatment, to save the patient's life.

Fever stage: Clinical symptoms will include: Sudden, continuous high fever. Headache, loss of appetite, nausea. Skin congestion. Muscle pain, joint pain, pain in both eye sockets.

There are often petechiae under the skin, bleeding gums or nosebleeds. Paraclinical: Hematocrit (Hct) is the index of red blood cells in the blood, normal. Platelet count is normal or gradually decreasing (but still above 100,000/mm3). White blood cell count is often reduced.

Dangerous stage: usually on the 3rd - 7th day of the disease. The patient may still have a fever or the fever may have subsided. There may be the following symptoms: Severe and continuous abdominal pain or increased pain, especially in the liver area. Vomiting.

Plasma leakage due to increased vascular permeability (usually lasting 24 - 48 hours). Pleural effusion, interstitial fluid (can cause respiratory failure), peritoneum, eyelid edema. If plasma leakage is large, it will lead to shock with symptoms of restlessness, restlessness or lethargy, cold extremities, rapid and weak pulse, stuck blood pressure or low blood pressure, unmeasurable blood pressure, undetectable pulse, cold skin, purple veins (severe shock), and little urine.

Subcutaneous hemorrhage: Scattered petechiae or hemorrhages usually on the front of the legs and inner sides of the arms, abdomen, thighs, flanks or purple patches.

Mucosal bleeding such as bleeding gums, nosebleeds, vomiting blood, black or bloody stools, vaginal bleeding or blood in the urine.

With severe bleeding: Severe nosebleeds (need to be packed with wicks or hemostatic gauze), severe vaginal bleeding, bleeding in muscles and soft tissues, bleeding in the digestive tract and internal organs (lungs, brain, liver, spleen, kidneys), often accompanied by shock, thrombocytopenia, tissue hypoxia and metabolic acidosis can lead to multiple organ failure and severe intravascular coagulation.

Severe bleeding can also occur in patients taking anti-inflammatory drugs such as acetylsalicylic acid (aspirin), ibuprofen or corticosteroids, a history of gastric or duodenal ulcers, or chronic hepatitis.

Some severe cases may have organ failure such as severe liver damage/liver failure, kidney, heart, lung, brain, impaired consciousness, failure of other organs. These severe manifestations can occur in patients with or without shock due to plasma leakage.

Recovery phase: Usually from day 7 to day 10: Fever decreases, platelet count gradually increases again, frequent urination, appetite returns. The recovery period can last for months.

According to Associate Professor, Dr. Do Duy Cuong, Director of the Center for Tropical Diseases, when there are signs of sudden, continuous high fever that does not subside, headache, body aches, patients need to go to medical facilities for doctors to examine, test and evaluate the signs and symptoms. Dengue fever needs to be diagnosed and treated early, avoid taking medicine and infusion at home.

The Aedes egypti mosquito is the main source of disease transmission. Mosquitoes often live in areas close to human habitation and urban areas. It is necessary to pay attention to handling and eliminating dark, humid areas and stagnant water environments that create favorable conditions for mosquitoes to breed and develop.

In addition, it is necessary to spray insecticides, kill mosquitoes, use mosquito repellents and traps, install mosquito screens on windows and use mosquito nets when sleeping.

Currently in Vietnam there is no vaccine or specific medicine for dengue fever. Therefore, when suspecting or having dengue fever, the patient should seek medical help, rest and drink plenty of water.

"Patients can take Paracetamol to reduce fever and relieve pain. Absolutely do not take Aspirin or Ibuprofen because these two drugs can increase the risk of bleeding," Associate Professor, Dr. Do Duy Cuong emphasized.
