How many days does it take for an adult to have a flu fever?

Adult influenza fever usually lasts for 3 to 5 days, and most people's body temperature can gradually return to normal during this period, but the specific course of the disease may vary depending on individual constitution, virus strain and treatment method. In order to relieve fever symptoms, in addition to taking medicine as prescribed by the doctor, you also need to pay attention to rest, replenish water and eat a proper diet.

1 Causes and course of influenza fever

Influenza is an acute respiratory infection caused by influenza virus. Fever is a protective response of the human body against viral invasion. Adult influenza patients usually develop fever within 1 to 3 days after infection, with body temperature mostly between 38℃ and 40℃. This fever is often accompanied by systemic symptoms such as fatigue, muscle aches, and headaches. If the immune system is normal and the treatment is appropriate, most people will recover from fever in 3 to 5 days, but individuals with low immunity such as the elderly, pregnant women, and patients with chronic diseases may take longer or even develop complications, so special attention should be paid.

2 Flu fever relief methods

①Drug treatment:

Use acetaminophen or ibuprofen: These antipyretics can effectively relieve high fever and pain, but they must be taken as directed by a doctor and should not be overused.

Antiviral drugs: such as oseltamivir and zanamivir, can shorten the course of the disease and need to be taken within 48 hours of symptom onset.

Watch for complications: If a high fever persists for more than 5 days or is accompanied by difficulty breathing, seek medical attention promptly and use antibiotics or more specific treatments to treat possible bacterial infections.

②Life conditioning:

Get enough rest: Getting enough rest during a fever allows the body to focus more on the immune system and speed up recovery.

Replenish water: When you have a fever, you sweat a lot, which can easily lead to dehydration. It is recommended to drink more warm water and clear soup. You can also drink electrolyte water in moderation.

Reasonable diet: focus on eating easily digestible and nutritious foods, such as porridge, chicken soup, and fruits, and avoid spicy, greasy and other irritating foods.

③ Physical cooling: Suitable for those whose body temperature does not exceed 39℃ and who feel unwell. They can wipe their body with warm water or apply ice packs to their foreheads, but avoid ice packs that are too cold and cause blood vessel constriction. When the fever exceeds 39℃, medication should be used to reduce the fever.

3 Situations that require vigilance and prompt medical attention

If the fever lasts for more than 5 days, the body temperature exceeds 40℃, or is accompanied by dyspnea, confusion, severe headache, chest pain, etc., it may indicate that the condition is getting worse or there are complications, such as pneumonia, otitis media, etc. In this case, you need to go to the hospital as soon as possible for further examination and treatment.

Although persistent high fever is tiring, it can usually be relieved with proper treatment and a good rest. If symptoms recur or do not improve, you should seek medical attention in time to deal with the complex health problems that may be caused by influenza.
