The symptoms caused by influenza A (H1N1) are basically the same as those of the common cold, and according to the characteristics of the Mexican cases, most of the deaths have respiratory symptoms, such as rapid breathing and breathlessness.

3. Preventive measures.

Experts believe that influenza A (H1N1) is controllable, and the virus is mainly transmitted through air and contact, so you should cover your mouth and nose when coughing or sneezing; Since influenza viruses can often survive on some surfaces of everyday products for a period of time, the prevention of influenza A (H1N1) should do the following:

No, this vaccine is mandatory, but there is also a certain fee, which seems to be more than 70 handfuls. It won't be long before Sichuan will be vaccinated.

I'm also a Sichuan drop.

According to the regulations of the National Health Commission, influenza A (H1N1) vaccine is a vaccine that falls within the scope of the national immunization program and can be administered in designated medical institutions. In general, the cost of influenza A (H1N1) vaccine is borne by ** and can be reimbursed. However, the exact reimbursement and reimbursement ratio may vary depending on the region and the medical insurance system.

It is recommended that you consult your local medical insurance institution or relevant departments before getting vaccinated to understand the local policies and regulations.

1. Influenza A vaccination is not mandatory, but voluntary, but must be strictly followed in four steps to ensure the safe and smooth progress of vaccination, namely, "informed notification, registration and inquiry, vaccination, and hospital observation".

2. Persons with contraindications to vaccination should not be vaccinated against influenza A. The contraindications to influenza A are similar to those for seasonal influenza, such as: those who are allergic to eggs, especially ovalbumin; Those who are suffering from a cold and fever, or suffering from acute diseases, serious chronic diseases, or acute onset of chronic diseases; Patients with Guillain-Barré syndrome; Patients with other progressive neurological diseases; Those with severe allergies, allergic to gentamicin sulfate; People under the age of 3 should not receive influenza A vaccination.

3. After vaccination, you need to observe for 30 minutes before leaving; If there is a slight reaction, no special treatment is generally required, and the vaccination unit can be consulted; In general, antiviral drugs should not be taken for two weeks.

4. Vaccinators should keep the vaccination site dry and clean for 24 hours, do not take a bath immediately, and rest more; If there is fever, redness, swelling and pain at the inoculation site, it is a normal reaction and can be recovered after 24 hours; If redness and swelling occur, apply a cold compress to the inoculation area, and if there is pain or induration, apply a warm compress to the inoculation area. If you have symptoms of serious adverse reactions, you should go to the hospital immediately.

The Ministry of Health has clearly pointed out that the following three groups of people are not suitable for H1N1 vaccination: first, children under 3 years old, and the current approved influenza A (H1N1) vaccine in China is suitable for people over 3 years old. Second, the contraindication to influenza A (H1N1) vaccine is acute illness, severe chronic disease, and acute exacerbation of chronic disease, so patients with nephrotic syndrome should be prohibited if they have an acute attack or the severity of the disease.

Third, the production process of the common seasonal influenza vaccine and the influenza A (H1N1) vaccine is basically the same, so people who are allergic to the common seasonal influenza vaccine cannot receive the influenza A (H1N1) vaccine; Recipients with a history of egg allergy, vaccination allergy and other severe allergies are prohibited from receiving influenza A (H1N1) vaccine, and those with a history of other allergies should carefully decide whether to receive influenza A (H1N1) vaccine under the guidance of a clinician.

If there is no above description, it is still recommended to get vaccinated, the country has put so much, the chance of a reaction is still very small!
