Introduction

Under normal circumstances, "Avian Flu" refers to the Influenza A virus. The initial symptoms mainly include fever and chills, coughing and sore throat, nasal congestion and runny nose, headache and muscle pain, fatigue, and general malaise. However, please note that the severity of symptoms caused by the Influenza A virus can vary, and symptoms may differ among individuals due to personal variations. If the above symptoms appear, prompt medical attention is advised.

Generally speaking, swine flu refers to the influenza A virus. The main initial symptoms include fever and chills, cough and sore throat, nasal congestion and runny nose, headache and muscle pain, fatigue and general malaise. A detailed analysis is as follows:

1. Fever and Chills

The most common initial symptom of the influenza A virus is fever, with body temperature rapidly rising above 38°C. Some patients may even reach 39°C or higher. Accompanying the fever, patients may feel cold and experience chills.

2. Cough and Sore Throat

Cough is also a common early symptom of the influenza A virus. It may be a dry cough or accompanied by phlegm. Sore throat is another typical manifestation, with patients possibly experiencing throat pain, dryness, or a burning sensation, which can affect swallowing and appetite.

3. Nasal Congestion and Runny Nose

As the condition progresses, some patients may develop nasal congestion and runny nose. Nasal congestion caused by the influenza A virus may be more severe, leading to difficulty breathing, affecting sleep and daily activities. Runny nose may also be more frequent and persistent.

4. Headache and Muscle Pain

In the early stages of the influenza A virus, patients may experience headaches, which can be severe or dull, affecting their quality of life and sleep. Muscle pain is also a common symptom, manifesting as general body aches, especially in the back and limbs. In severe cases, it can even affect walking and daily activities.

5. Fatigue and General Malaise

Influenza A virus patients often feel extreme fatigue and general malaise, which is difficult to relieve even after rest. The fatigue may be accompanied by symptoms such as overall weakness and low spirits, significantly impacting daily life and work efficiency.

However, it should be noted that the severity of symptoms caused by the influenza A virus varies, and individual differences may lead to different presentations. If the above symptoms appear, especially during flu season, timely medical attention is necessary. Doctors will perform appropriate examinations and treatments based on the patient's condition. At the same time, maintaining good personal hygiene habits, such as wearing masks, washing hands frequently, and avoiding gatherings, can help prevent the occurrence of respiratory infectious diseases like swine flu.

Why is early diagnosis of gallbladder cancer difficult?

In general, early diagnosis of gallbladder cancer is difficult, mainly due to atypical early symptoms, the concealed location of the gallbladder, easy confusion with other gallbladder diseases, small tumor size in the early stage, and a lack of specific screening methods. If you experience any discomfort related to the gallbladder, it is recommended to promptly seek medical evaluation at a正规 hospital to complete necessary examinations. In addition, individuals with underlying conditions such as gallstones or chronic cholecystitis are at higher risk.
