Why Can the Flu Be Life-Threatening?
Jiang Shaohua, Deputy Director of the Emergency Department at Hainan Cancer Hospital, explains that influenza is an acute respiratory infectious disease caused by the influenza virus. In cases without complications, it is usually self-limiting and most people recover on their own.
However, some patients may develop complications such as pneumonia, bronchitis, and myocarditis. Certain groups, including the elderly (≥65 years old), young children (<5 years old), pregnant women, obese individuals (BMI >30), and those with weakened immune systems, are at a higher risk of severe influenza and should take extra precautions.
How to Differentiate the Flu from a Common Cold?
Flu Symptoms are severe and develop rapidly, often with a high fever exceeding 38.5°C, along with cough, sore throat, and significant systemic symptoms such as headache, muscle aches, and extreme fatigue.
The common cold usually causes mild to moderate fever, with less severe symptoms primarily including nasal congestion, runny nose, and sneezing.
Since the flu is a viral infection, treatment focuses on symptom relief and antiviral therapy. Taking specific antiviral medication within 48 hours can significantly improve recovery.
Currently, oseltamivir phosphate and baloxavir marboxil are commonly used antiviral drugs for the flu.
Annual flu vaccination and maintaining good personal hygiene remain the best ways to prevent the flu.
Expert Reminder: During the Flu, these are the things you must not do to prevent worsening symptoms or virus spread
Avoid Taking Hot Baths: During the flu, your body is already in a weakened state. Taking a bath, especially a hot one, may disrupt body temperature regulation and worsen symptoms. Additionally, high temperatures cause pores to open, making you more vulnerable to cold exposure and further illness.
Avoid Strenuous Exercise: While light activity may be beneficial, strenuous exercise should be avoided during the flu. It increases metabolic stress, weakens the immune system, and worsens fatigue, making it harder for your body to fight off the virus and to recover.
Do Not Stop Medication Prematurely: Flu treatment requires a full course of medication. Even if symptoms improve, stopping medication too early may leave the virus incompletely cleared, increasing the risk of relapse.
Do Not Take Antibiotics Unnecessarily: Antibiotics do NOT work against flu viruses. Misusing them can lead to antibiotic resistance and unwanted side effects if taken without medical necessity.
Ensure Proper Rest and Nutrition: During the flu, you should get enough rest and avoid excessive fatigue. Eat nutritious, easily digestible foods, stay hydrated, and avoid spicy or greasy foods to support your recovery.
Reminder: Following these precautions can help flu patients recover more smoothly and reduce the risk of complications. If symptoms persist or worsen, seek medical attention promptly.
