The face of Influenza A H1N1 flu how to protect themselves and others in the area of prevention, vaccination is not necessary to go crowding together of people influenza vaccine, because prevention is the prevention of seasonal influenza vaccine is not effective swine influenza. The correct approach is to develop good personal hygiene, adequate sleep, hard exercise, reduce stress, adequate nutrition; wash their hands frequently, especially after the first contact with public goods, wash their hands and then touching their eyes, nose and mouth; sneezing and cough, when should you cover your nose and mouth with tissue paper; room to maintain ventilation.
1, reducing to the public the opportunity to crowded places, for those who demonstrate physical discomfort, fever and cough symptoms, to avoid close contact with;

The title of the unscientific nature of Influenza A (A type) H1N1 influenza, there is a certain unscientific nature of the title. Many people first heard there will be swine flu, and therefore had a fear of pork, and some countries also in order to prevent a large-scale swine flu began killing pigs or prohibiting the ground pork. There is no in pigs were found to have this virus, some people - especially the pig-raising industry who - for the pigs Ming Buping that the pig has been wronged. In order not to allow pigs to play the notoriety of the World Health Organization called for a while after the swine flu, called the A H1N1 influenza, it finished as the national influenza A H1N1 influenza, the media sometimes simply referred to as influenza. This referred to as highly inappropriate. Influenza viruses are divided into A, B, C (or A, B, C) into three types, one of the most common is the influenza, seasonal influenza each year most of the popular Influenza. Therefore, to this particular flu known as influenza A is not simply that it can distinguish between ordinary flu.
In the existence of two kinds of influenza virus surface protein. A way to get the blood red blood cells together, so called haemagglutinin (HA for short, or H). Another protein able to neuraminidase (a kind of sugar molecule) broken down, so they are called neuraminidase (NA for short or N). These two proteins because of exposure to the outside of an influenza virus, influenza virus enters the human body, they become the target of the immune system. If these two proteins appeared in mutation, the immune system can not identify them, influenza viruses will be able to escape to. Therefore virologist under variation of these two proteins to give further classification of influenza viruses, compiled on a different number. The influenza A H1N1 subtype of influenza is that the two figures to represent their hemagglutinin and neuraminidase type. This subtype of influenza virus is not newly discovered, resulting in 1918 ~ 1919 influenza pandemic H1N1 influenza virus subtype is. It is actually the most common subtype of influenza virus in 2006, about half of the seasonal influenza is that it caused. Therefore, it is called influenza A H1N1 influenza this flu, the same does not indicate their specificity.

Citation 1: Prevention of Influenza A H1N1 influenza (swine flu)
What preventive measures? U.S. CDC Acting Director Richard Bessel, said influenza virus is mainly spread through the air and contacts, so when coughing or sneezing should cover your mouth, nose; due to influenza virus can often be in a number of everyday survival on the surface for some time , it should wash their hands, but also often use alcohol to disinfect daily.

To maintain hand hygiene is the primary condition for the prevention of infectious diseases. To help prevent influenza A H1N1 influenza. Wash their hands thoroughly with disinfectant hand sanitizer or disinfectant to disinfect hands medical hand hygiene can be maintained.
Prevention of swine influenza 10 Q 10 A: 10. What precautionary measures?

Swine influenza as a kind of flu, you can use the traditional Chinese medicine theories and methods of treatment, from a Chinese medicine perspective, the flu is a feeling of alien evil, passenger in the lung, closed its chiang, lung may not have decreased, the person must clear tears flow , fever, evil wind, aversion to cold, headaches, body pain and other conditions. France should declare casual, such as Gui Zhi Tang, ephedra soup, Pueraria noodles in soup. If not treated in time will switch to the internal injuries, while the chill caused decline in kidney-yang-sheng, Shenluotong in the lung, heart and lung within the yang are not sufficient, unifying body fluid, while the flow of clear nasal discharge, the patient's foot must not levy Exogenous more sleepiness without God, or sneeze endlessly, or cold feet, France should Fu-yang, such as Sini Tang, White Pass soup, Fengsuidan, Mahuangfuzixixin Tang, Gui-noodles in soup.
TCM stress syndrome differentiation, according to different types of influenza were treated, there is a trick: Where see sneezing, tears streaming clear, stuffy nose, without other symptoms, they are within the cold cold, regardless of severity, clothes Sini Tang, ephedra Fuzi Fine Xin Tang Bi-efficiency, disease to medicine only, without leaving any sequelae. Other cold medicine if the service is bound to null and void, and will also make Evils deepen increase, conversion to lung and kidney and other serious illnesses.

Construction of swine influenza virus genetic engineering subunit vaccine There are several ways in which more reports include:
1) the use of prokaryotic expression system (E. coli system) or eukaryotic expression system (yeast) in the in vitro expression of swine influenza virus strains in the HA gene and NA genes, and then harvested, concentrated and purified target protein, the system further vaccination with . This approach has the advantage of simple preparation process, the purpose of protein yield, the main component can be quantitatively configuration. However, in vitro expression of the protein is difficult to maintain or restore the spatial structure of natural proteins, protein purification process is complicated and costly, but not the overall effects of immunization and traditional whole-virus inactivated vaccine, and therefore from the technological aspects of such vaccines needs further improvement .

Subunit vaccine is by physical chemical methods or genetic engineering methods to obtain the main immunogenic proteins of pathogens made of a vaccine which can effectively avoid the use of all pathogens, the biological production of vaccines and lead to security risks, and help to improve the active ingredient in vaccines the concentration, purity, and the development of multivalent, multi-combined vaccine. Has successfully developed sub-unit vaccines, including VPI-mouth disease virus subunit vaccine, Mycobacterium tuberculosis ribosomal subunit vaccine, a variety of bacterial exotoxin subunit vaccine, hepatitis B virus surface antigen subunit vaccine. To date, the development of influenza vaccines for human use has experienced three periods, the first-generation vaccine is an inactivated whole-virus vaccine, the first two semi-cracking generation vaccines, 3rd generation cracking the whole virus, subunit vaccine. Compared with the previous 2-generation vaccines, 3rd-generation vaccines to further remove the virus components have little to do with immune function and stress on the body has the role of macromolecular protein and heat transfer, while the main immunogenic antigen of influenza virus hemagglutinin ( HA) and neurological acid enzyme (NA) concentration, so this vaccine to the body's stress is small, fast rise in antibodies after vaccination to maintain long time, has a good immune effect, but also has a higher bio-security. At present, populations in many countries have begun to use the first three-generation full-lysis of influenza virus subunit vaccine. But for swine flu, this sub-unit vaccine production costs are too expensive in the short term mainstream is unlikely that the immune products. On the contrary, people put more attention to the 4th generation of genetic engineering subunit vaccine.

In the swine flu vaccine has been developed, the technology of the most mature and are mainly used in the production H1NI type and price or bivalent H3N2 subtype swine influenza inactivated whole-virus vaccine. Mostly in the form of oil-adjuvant vaccine, inactivated agents commonly used formaldehyde or BEI. It was reported that swine influenza inactivated vaccine can effectively protect weaned piglets and pigs against SI, so that the incidence was reduced by 30% to 70% so that the deaths fall by 60% ~ 87%. At present, such vaccines have achieved a number of countries in Europe and the United States commercial providers, such as the Intervet's End-FLUence (with Imugen) and the End FLUence (with Microsol Diluvac Forte), Pfizer Inc. FluSure, and Schering Plough Animal Health Corporation MaxiVac-FIu, MaxiVac Excell 3 and so on. China South China Agricultural University, Harbin Veterinary Research Institute, and other units are also swine influenza oil-emulsion inactivated vaccine development has done a lot of work, its research results show that the cultivated strains isolated from China after the preparation of the H1 subtype; 91H3 subtypes unit and bivalent swine influenza oil-emulsion inactivated vaccine after the first 3 weeks after immunization Hl antibody titer 1:160 can be achieved for more than 4 weeks after vaccination HI antibody levels of more than 1:400, to 12NHI antibody titers after immunization can still maintain 1:100 or more, more than 1:80 of antibody-positive criteria. If you make two free, then the higher levels of HI antibody, effective period of protection can be achieved more than 6 months, fully able to meet the immunization needs of a variety of day-old pigs. Currently, these vaccines have been through clinical testing, is to declare a new veterinary certificate, I believe that in the near future can be made for commercialization of the vaccine on the market.
Swine influenza inactivated whole-virus vaccine, while having safe, efficient, low production costs, long duration of effective antibodies, etc., but there are also slower to produce antibodies and induce cellular immune capacity of weak and strong enough stress response. In particular kinds of drugs, mostly from the vaccine strain in the epidemic, once the vaccine, the virus occurred during the leak, likely to cause environmental pollution, trigger a new outbreak. To this end, scientists have also been exploring the development of new swine flu vaccine.
