Caution Against Sudden Increase and Severe Complications of Influenza A

Seasonal flu cases have seen a sharp increase in the last two weeks, particularly in the Respiratory Infectious Diseases Department at a major Military Hospital, which reports approximately 20-30 patients seeking treatment and nearly 30 confirmed Influenza A cases requiring daily inpatient care. The rapid spread typically peaks during the winter-spring season, as cold and humid weather conditions favor viral development.

Disease Characteristics and Complication Risks:

The flu virus spreads rapidly through the respiratory tract via droplets from coughing, sneezing, or contact with contaminated surfaces. Influenza A usually has a sudden onset with symptoms such as high fever (38-40°C), cough, sore throat, nasal congestion, headache, fatigue, and muscle aches. Most healthy individuals can recover spontaneously after 5-7 days.

However, Influenza A can cause severe complications, especially in high-risk groups such as:

• Individuals with Underlying Conditions: Those with cardiovascular disease, hypertension, diabetes, COPD, obesity, chronic kidney disease, and the elderly. This group is susceptible to secondary infections like pneumonia and bronchitis.

• Pregnant Women: Require close monitoring of their respiratory status and pregnancy progression, with careful consideration given to fetal-safe medications to avoid dangerous complications.

Common complications include pneumonia, respiratory failure, exacerbation of underlying diseases, and severe infections.

Prevention and Treatment Recommendations:

Infectious disease specialists recommend that people take proactive and effective measures against Influenza A by:

• Seasonal Flu Vaccination: This is the most effective measure to reduce the risk of illness and complications.

• Hygiene Practices: Covering the mouth and nose when coughing or sneezing (preferably with a tissue, handkerchief, or the crook of the arm); frequently washing hands with soap; avoiding indiscriminate spitting, and limiting unnecessary contact with people infected or suspected of being infected with the flu.

• Avoid Self-Medicating: If infected, patients should not self-medicate with antiviral drugs (such as Tamiflu) or antibiotics. Patients need to see a doctor for consultation and take medication only as directed by the physician.
