How do you know it's influenza A?

Influenza virus can be routinely detected by:

First, viral antigen detection: viral antigen detection can be performed using the colloidal gold method and the immunofluorescence method. Antigen detection is fast and is a commonly used influenza virus detection method in hospitals. Due to the limitations of the detection method, a positive viral antigen test supports the diagnosis, but a negative test cannot completely rule out influenza.

Secondly, viral nucleic acid testing: mainly testing influenza virus nucleic acid in patients' nasal swabs, throat swabs, nasopharyngeal swabs, tracheal extracts, and sputum. Viral nucleic acid testing has high sensitivity and specificity, and can distinguish between virus types and subtypes.

Which groups are at high risk of severe influenza A?

People over 65 years old, children under 5 years old, people with underlying diseases, people with weakened immunity, pregnant women and women who have given birth within 2 weeks, and obese people (BMI> 30).

What should I do if I have influenza A?

Influenza, including influenza A, is a self-limiting disease. The fever will gradually subside 3-5 days after the onset of the disease, and symptoms such as headache, muscle and joint pain will also gradually ease.

If you have flu symptoms, don't panic. You can deal with it in the following ways:

If you are in good mental state, have no obvious headache, normal appetite, and your fever is below 38°C, you can be observed at home, drink plenty of water, eat more vegetables and fruits, eat a light diet, and ensure sleep.

If you have a high fever, with a body temperature over 38.5℃, accompanied by headache, body aches, mental fatigue, vomiting, diarrhea and other symptoms, you need to go to the hospital's fever clinic for treatment.

Reduce contact with others, stay at home as much as possible, pay attention to indoor ventilation when at home, keep a distance from your family, and wear a mask when going out.

Is there any specific medicine to treat influenza A?

First of all, it should be pointed out that not everyone who has the flu needs to take antiviral drugs. Most flu antiviral drugs are prescription drugs and must be evaluated by a doctor before use. Antiviral drugs cannot replace annual flu vaccinations for prevention.

At present, the main influenza antiviral drugs available in China include oseltamivir (including granules and capsules), zanamivir, peramivir, arbidol and mabaloxavir.
