Note: pressing the prevention of influenza

Influenza is a major hazard and reach broad respiratory diseases, epidemic density in China is quite different north and south, the North than the South, severe and longer duration. From the flu several times in the history of the harm caused by sweeping the global point of view, it was a storm is no exaggeration. But this "crisis" is to prevent or contain this end, we need to have a preliminary understanding of disease.

Both influenza and common cold are different

Influenza and the common cold is different, and should not be confused. Influenza occurs in winter and spring, often forming large-scale epidemic, serious or even cause a worldwide pandemic. More acute onset patients, body temperature rises rapidly, often more than 39 degrees Celsius; heavy systemic symptoms such as headaches, body aches, weakness and so on. Upper respiratory tract symptoms are not very prominent, such as nasal congestion, runny nose, dry throat and other symptoms have been low. Children are more systemic symptoms, may have abdominal pain, diarrhea, vomiting and even convulsions. The common cold is only in close contact with small groups of people within the popular, slow onset, most of the heat is not more than 39 degrees Celsius, 38 degrees Celsius are more and more obvious upper respiratory symptoms such as cough, sore throat, nasal congestion, sneezing , runny nose and other symptoms become very prominent, but systemic symptoms such as headache, body aches, cold and other light than the flu.

The dangers of influenza can not be ignored

Influenza and the common cold caused by the different results between China ,1957-1958 influenza epidemic, the case fatality rate was 0.24% -1.40%. Why does influenza cause death? First cause primary influenza pneumonia, the pneumonia caused by a virus, more common in patients with existing heart and lung diseases or pregnant women. Most people suffering from the flu within a week after the return to normal body temperature, but with primary viral pneumonia in patients with slow heat reclaim, and shortness of breath increased, there array cough, hemoptysis and other more severe symptoms; second reason is that place bacterial pneumonia, influenza is often associated with Staphylococcus aureus, pneumococcal or Haemophilus influenzae and other bacterial pneumonia exacerbations; third, concomitant viral and bacterial pneumonia; Fourth, toxic shock syndrome, cause respiratory failure, circulatory failure and so on. Thus, influenza and common cold is indeed very different, must be vigilant.

China's information shows that people die from flu to 5 years of age and 50 years old are most welcome. Most children die from pneumonia, above, and originally with chronic bronchitis, bronchial asthma, emphysema, tuberculosis or heart disease such as people over the age of 50, once got the flu, are more vulnerable to a variety of the threat of pneumonia and life-threatening.

Prevention of influenza, urgent

Local health departments should strengthen the monitoring, timely detection of problems. Foci residents also pay attention to, once found more than two families of suspected influenza patients with high fever and when other family members should take timely preventive measures.

In addition to the prevention of influenza during the influenza epidemic to public places and avoid crowded places (especially in patients with chronic diseases mentioned above), and keep in sneezing or coughing for more than 1 meter distance (because droplets of the virus can be inside at close range communication), the can take the following measures:

1. Maintain good indoor ventilation

Many offices are now closed for the whole, beneficial to the virus remain, it should be to make air circulation. Patients discharged from sneezing and respiratory virus can be airborne 10 hours, when conditions permit, can be suspended for more than two days and nights, so even if the beginning of winter frost cold days have to ventilation.

2. Wash their hands

Inanimate objects, because the virus can survive on 3 hours, during which, if inadvertently touching contaminated objects, sticks to the virus and inadvertently hand touch his nose or eyes, it is likely to be infected, so is very important to wash hands.

3. Drug Prevention

Amantadine inhibition of influenza A virus but ineffective against influenza B (a small country in recent years, influenza B is also popular). 0.1 g for each use of oral, twice daily, can Lianyong 14, but has some side effects such as excitement, insomnia, dizziness, epilepsy patients and pregnant women, Jiyong; also take appropriate Banlangen granules, or Banlangen and consistent Public decoction.

4. Vaccinated

Currently commercially available influenza vaccines are imported, also made in China, in accordance with the requirements of the World Health Organization with a 1 subtypes, A 3 and B subtype virus, hope the body can produce antibodies after injection with the virus against the corresponding type infection. Elderly persons, children and the foregoing can be injected in patients with various chronic diseases, others such as students, military, transportation department employees, medical staff, caregivers and other groups can also be injected. It should be noted, the vaccine is only a defensive role with the virus, while the influenza virus changes easily 72, once the big variation of the virus, the vaccine will not achieve the original preventive effect, it would need new vaccines the scientists . Hazards of the above influenza, pneumococcal pneumonia is one of the causes of death. In order to prevent high-risk groups mentioned above concurrent bacterial pneumonia, pneumococcal vaccine can be injected to prevent disease progression in patients, complex.
