What control measures should be taken for influenza A (H 1N 1)?

The symptoms of human infection with swine flu are similar to those of a cold, and patients may have fever, cough, fatigue, loss of appetite and other symptoms. In terms of prevention, there is no need to get together for flu vaccines at this stage, because seasonal flu vaccines have no effect on preventing swine flu. The correct way is to develop good personal hygiene habits, get enough sleep, exercise diligently, reduce stress and have adequate nutrition; Wash your hands frequently, especially after touching public goods, and before touching your eyes, nose and mouth; Cover your nose and mouth with paper towels when sneezing or coughing; Keep indoor ventilation, etc.

The incidence of the disease is high, the incubation period is 2 ~ 7 days, and the course of the disease is about 1 week. At the beginning of the disease, sick pigs suddenly have symptoms such as fever, listlessness, loss of appetite or abandonment, often lying together, unwilling to move, having difficulty breathing, coughing violently, and mucus flowing out of eyes and nose. If the treatment is not timely in the onset period, it is easy to be complicated with bronchitis, pneumonia and pleurisy, which will increase the mortality rate of people.
