What are the symptoms of contracting H1N1 flu within 1-5 days after infection?
Disease description:
Because the influenza A virus has been prevalent recently, my wife went shopping a couple of days ago without proper protection and unfortunately got infected. I heard that there are obvious symptoms a few days after infection. Could you please tell me what symptoms may appear 1-5 days after contracting influenza A?

Dr. Ren Yi
After infection with H1N1 influenza, symptoms such as fever, cough, sore throat, and muscle pain typically appear, although the presentation may vary from person to person.
1. Fever: Following infection with H1N1 influenza, patients typically experience a sudden high fever, with body temperature rapidly rising above 39°C, even exceeding 40°C. The high fever may persist for 3-5 days and is often accompanied by chills and shivering.
2. Cough: Coughing is one of the common symptoms of H1N1 influenza and may present as a dry cough or a productive cough. As the illness progresses, coughing may become more frequent and severe. By the fifth day of illness, although the high fever may subside, coughing and phlegm production may persist.
3. Sore throat: The influenza A virus can cause inflammation of the throat mucosa, leading to dryness and throat pain. Some patients may also develop redness, swelling, or blisters in the throat area. Sore throat may appear early in the illness and persist throughout the course of the disease.
4. Muscle pain: Patients with H1N1 influenza often experience muscle and joint aches, which may result from the virus-induced systemic inflammatory response. Additionally, patients may feel extremely fatigued and weak, with symptoms that are difficult to relieve even after rest.
During the infection period, patients may take antiviral oral solution, Lianhua Qingwen capsules, oseltamivir phosphate capsules, and other medications as directed by a physician. Maintaining good lifestyle habits and a healthy diet will also help speed up the recovery process.
