豬流感: 症狀, 傳染, 診斷 & 預防

Swine flu, officially known as H1N1 influenza, is a contagious respiratory illness caused by influenza viruses that typically infect pigs but can also spread to humans. Understanding how swine flu spreads, 如何診斷, and how to prevent it is essential for protecting public health—especially during seasonal outbreaks.

What Is Swine Flu?

Swine flu is an influenza A virus subtype (H1N1) that first gained global attention during the 2009 pandemic. 自那以後, it has continued to circulate as a seasonal flu strain.
It commonly causes respiratory symptoms similar to typical influenza but may be more severe in children, older adults, pregnant women, and people with weak immune systems.

How Swine Flu Spreads

Swine flu spreads from person to person, primarily through:

• Respiratory droplets from coughing or sneezing

• Touching contaminated surfaces

• Close contact in crowded environments

Early detection and hygiene practices are crucial to reducing transmission.

Common Symptoms of Swine Flu

Swine flu symptoms resemble regular flu symptoms, 包括:

• 發熱

• 咳嗽

• 咽喉痛

• 身體酸痛

• 頭痛

• 疲勞

• 流鼻涕或鼻塞

• 在某些情況下, vomiting or diarrhea

Seek medical care immediately if symptoms worsen or breathing difficulties occur.

How Swine Flu Is Diagnosed

Accurate diagnosis is essential for proper treatment. Healthcare providers typically collect respiratory specimens using:

1. Nasal Swab Test

A 鼻拭子 is inserted into the nostril to collect mucus from the upper respiratory tract. This is one of the most common and painless specimen collection methods for H1N1 detection.

2. Nasal Wash or Nasal Aspirate

A nasal wash or nasal aspirate involves flushing or suctioning fluid from the nasal cavity to obtain samples. These methods may provide higher viral loads for testing and are commonly used in hospital settings.

These specimens are then tested using molecular diagnostic techniques such as 逆轉錄聚合酶鏈反應, the gold standard for influenza detection.
