Introduction

In recent months, the flu A virus has been causing complex outbreaks and severe cases, even leading to critical conditions in northern Vietnam. Many patients have required hospitalization and intensive care measures, including the use of ECMO (artificial heart-lung support). The rapid progression of the disease has posed significant challenges for doctors, especially for those with underlying health conditions. This article provides detailed information on severe flu patients and effective preventive measures.

Main Content

1. Symptoms and Progression of Flu A

Flu A typically starts with common symptoms such as high fever, headache, sore throat, cough, runny nose, and fatigue. However, in some cases, especially among elderly individuals and those with pre-existing conditions, the disease can rapidly progress to severe respiratory distress. Some patients have required mechanical ventilation, and in extreme cases, ECMO to sustain life.

2. Severe Flu Cases

a. Mr. Quang

Mr. Quang, a 65-year-old male patient, was hospitalized after a week of flu symptoms. Initially, he received oxygen therapy through a nasal cannula, but his condition quickly worsened, necessitating mechanical ventilation. He was then transferred to the National Hospital of Tropical Diseases where ECMO was used due to severe lung damage.

b. 87-Year-Old Female Patient

An 87-year-old female patient, with a history of COPD and hypertension, was admitted to the hospital after three days of flu symptoms. After treatment, her respiratory condition improved significantly, reducing the need for oxygen and increasing alertness.

c. 82-Year-Old Male Patient

An 82-year-old male patient, with diabetes, hypertension, and COPD, was hospitalized after two days of flu symptoms. He was diagnosed with sepsis, shock, and myocardial infarction. Currently, he is still dependent on vasopressors to maintain life.

3. Conditions of Severe Flu Patients

According to Dr. Pham Van Phuc, Deputy Director of the Intensive Care Center at the National Hospital of Tropical Diseases, severe flu patients often experience rapid deterioration, particularly among the elderly and those with underlying health conditions. The main cause is weakened lung function and immune systems, allowing the flu virus to spread and damage the respiratory system more quickly.

4. Complications and Challenges in Treatment

In addition to direct lung damage caused by the flu, severe flu patients also face complications such as bacterial or fungal pneumonia and myocarditis. These require coordinated treatment from multiple specialties, adding to the difficulties faced by medical staff.

5. Prevention and Management of Flu

In light of the complex flu situation, getting vaccinated is strongly recommended. Additionally, people should practice good hygiene, avoid crowded places, and wear masks when necessary. Early medical attention is crucial if flu-like symptoms appear.

Conclusion

The flu A virus is causing many severe and critical cases, particularly among the elderly and those with underlying health conditions. Vaccination and preventive measures are crucial to reduce the risk of infection. People should pay attention to their health and seek medical help promptly if they notice any unusual symptoms. It is hoped that this information will provide readers with a clearer understanding of the situation and how to manage the flu.
