(A) symptomatic support.
In patients with suspected and diagnosed on the spot should be treated in isolation, emphasizing early treatment.
Right people are infected with swine influenza are mainly integrated symptomatic supportive care. Note that rest, more water, pay attention to nutrition, to closely observe the patient's condition; incidence of the early period of 48 hours is the best treatment for high fever, clinical symptoms, shall shoot chest, checking blood gas.
(B) drug treatment.
1. Antiretroviral therapy: should be an early application of antiviral drugs, oseltamivir can be a trial (oseltamivir Tamiflu). Tamiflu is a neuraminidase inhibitor, for swine influenza virus may be inhibited, dose 75mg / d, course of five days, children used with caution. From the United States swine influenza virus has recently infected with the virus isolated from oseltamivir and zanamivir (zanamivir) is sensitive, resistant to the amantadine and rimantadine. Relenza, its role is to inhibit influenza virus through the nervous acid activity, to achieve the anti-viral effect. Relenza (Relenza) of new drugs, is the first FDA confirmed that one can simultaneously for A-, B-type influenza inhalation therapy drugs. Influenza vaccine is the "prevention", the flu drug is a "treatment", and previous flu drug is different is that the main component Relenza Zanamivir is a neurological deaminase inhibitor, the virus in the respiratory enzyme needed in the role of neural amine in order to spread open to, once the nerve has been Relenza deaminase to contain the virus can not spread in the respiratory tract, thus resolving the problem of influenza viruses.
2. Antibiotics: In case of bacterial infection could be the use of antibiotics.
(C) TCM treatment.
1. Lung Wei poison attack.

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?
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 disinfectant for daily necessities disinfection. In addition, less crowded places in the human "bunches," is also to reduce the probability of infection in an effective way. Finally, if once found to contract the disease, patients should avoid going out to prevent the virus to infect others.
AHD2000 ® hand and skin disinfection liquid (Influenza A H1N1 flu disinfectant)
Prevention of Influenza A H1N1 influenza first priority is to wash their hands
From the cleaning and disinfection, food safety and infection prevention experts pointed out that the prevention of influenza A H1N1 influenza The basic priority is to do personal hygiene, as well as daily work and living environment of the cleaning and disinfection.
Countries such as China and the U.S. Center for Disease Prevention recommends the use of alcohol-based hand disinfectant to strengthen the prevention of infection. Experts emphasized that to master the proper hand-washing methods and the correct hand disinfection, can be truly effective in killing Influenza H1N1 influenza viruses.
Swine influenza disinfection, hospital infection control and personal protection technology program: the medical staff of personal protective 3, each contact with patients immediately after the hand-washing and disinfection. Hand disinfection with quick hand rub disinfectant 1-3 minutes.
Ministry of Health: Influenza A H1N1 influenza foci disinfection guidelines (1) at any time disinfection 2. Medical personnel and Chaperone shall upon request and proper personal hygiene protection, treatment, care should wash their hands after work and disinfected. (Vii) Hand: Quick-drying hands with alcoholic hand disinfectants disinfected.
Wash their hands with disinfectant hand sanitizer, the program is as follows:
[2] (1) open the tap washing hands.
(2) by adding hand-washing liquid, hand given rise to a bubble.
(3) at least 20 seconds time to rub with the palms, back of the hand, that gap means the back, thumb, fingers and wrists, rub, when not to flush.
(4) Scrub hands thoroughly with water after the rinse.
(5) with a clean towel or paper towels to dry thoroughly hands, or with a dry towel hand dryer.
(6) Wash your hands, do not touch the water tap directly again, can first wrap the faucet with a paper towel, put off the tap; or splashing water to clean the faucet.

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.
Therefore, the treatment of influenza are taking drugs Treatment of Exogenous will not have any good results. Moreover, convergence in the body also will be Yinxie, to a certain time will attack. The current middle and western medicine treatment, have once again Yinxie the role of convergence, so after repeated accumulation, eventually leading to asthma, rhinitis, pharyngitis, bronchitis and other respiratory diseases.
Traditional Chinese medicine with Western medicine treatment of influenza is completely different pathogenic viruses do not have to take into account only the patient's specific symptoms according to syndrome differentiation, therefore, whether swine flu or some other flu medicine can be treated the same way, while the treatment premise is dialectical.
The incidence of influenza or plague are the timing and region has its own rules to follow in a fixed. Because influenza and plague have a "warm" and "dry" nature, generally occurs in spring and autumn, or at the turn of the season. Therefore, there is an outbreak in the spring more from the south began, and gradually with increasing temperature and the northward development of; while more than autumn there is an outbreak starting from the north, and gradually decrease as the temperature development in the south. This is the influenza virus (or plague virus) will be as a hotbed of climate temperature and changes in the body mutate reasons.
At the same time, the incidence of influenza and plague the region are often associated with the local living habits (lived a fast life) and medical fashion (abuse of tonic, cold medicine or antibiotics) has a close relationship. For example: the plague of livestock, mainly due to reduced activities castrated while in captivity, fed with hormones to stimulate egg production a large number of other factors, so that the resistance of livestock have greatly diminished, thus making it difficult to resist against the plague. Of human infection with the plague, also owing to lack of exercise, diet section, lack of vitality caused by excessive sexual intercourse, low immunity.
In short, with the ever-changing biotechnology, swine flu vaccine work will continue to push forward, the new vaccine will be more secure and effective. It must be stressed is that, for swine flu prevention and control, must not rely solely on this vaccine as a means of strengthening the daily feeding and management, good bio-security protection and comprehensive bio-security measures is the key.

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 .
2) The swine influenza virus immunogen (HA and NA) gene alone or with cytokines (interleukin -6, Y interferon, etc.) in series after the encoding gene was cloned into the eukaryotic expression plasmid, and then recombinant DNA quality particles into the body cells through the body-derived expression and presented to the immune system to induce specific immune response produced by a host, to play a protective effect, which is the so-called DNA vaccine. The results show that relying solely on swine influenza virus HA gene DNA vaccine immunization results were not ideal (low levels of specific antibodies, to attack drug to protect poor), if co-expression of some immune regulatory role of cytokines, or the use of DNA vaccine and then with conventional inactivated vaccines to enhance immunity, you can significantly improve the immunity level of protection. Overall, however, the immune effect of such DNA vaccines is not true that repetition is poor, with the traditional than the whole inactivated virus vaccines are still a certain gap from the laboratory stage to develop a molding products also require a longer time asked.
3) live vector genetically engineered subunit vaccine. At present, this is the people placed great hope, and a possible commercialization of the vaccine. Be used as a carrier including human adenovirus type 5 (human adenovirus 5, HAd5), porcine adenovirus type 3 (porcine adenovirus 3, PAV3), porcine pseudorabies virus (PRV), baculovirus (baculovirus) and so on. One study based on more mature adenovirus vectors genetically engineered swine influenza subunit vaccine, such as the South China Agricultural University and other units in the development of some products have entered the safety assessment of genetically modified and clinical experimental stage, is expected to develop good prospects. Adenovirus vector has many advantages: ① relatively stable particles of adenovirus, the virus genome rearrangement in low frequency in the packaging cells can replicate efficiently; ② good safety has not been found in adenovirus integration with the host genome; ③ adenovirus group than in large (about 36kb), the capacity of exogenous genes are also large (now confirmed that exogenous DNA insert capacity of up to 7.5kb); ④ In addition to adenovirus reproduction in the intestinal and respiratory tract, it also can infect the liver cells, vascular endothelial cells , vascular smooth muscle cells, glial cells and other somatic cells, and, for the receptor cells infected with adenovirus in the mitosis is not strictly required; ⑤ adenovirus vector is very easy to direct the transfer of foreign genes into target cells, allowing their access to effective expression. Study confirmed that, with carrying H1N1 subtype swine influenza virus HA S ~ HNA gene recombinant adenovirus vaccine (2 × 109TCID) on the 40-day-old experimental pigs 2 weeks after immunization, Hl antibody level of more than 1:160, can be effective against the same sub - type swine influenza virulent attacks. It is constantly developing new genetic engineering of live vector vaccine, it is also concentrated efforts to resolve the antigen, the second by the initial immune antibody immune interference, part of the pig cell vaccine allergies and other issues, hoping in the near future of such vaccines can be widely application, as a traditional whole-virus inactivated vaccine supplement.

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.

1, visited the affected areas, or with the pigs and the history of close contact with influenza patients, 1 week clinical manifestations of influenza appeared in those who are suspicious. Of course, if there is no clear medical history, can not rule out the possibility of illness.
2, without fever, there is generally a preliminary diagnosis of exclusion, particularly in patients with body temperature of less than 38 °. But the disease can not continue to fever, a rare low-grade fever are not even heat. .
3, is very similar to common flu symptoms (fever, cough, runny nose, headache, sore throat, body aches, vomiting, etc.) that, with symptoms (ie your description) simply can not be confirmed.
4 assistant examination beneficial to diagnosis: tests: WBC count was not normally high or lower. More than the total number of critically ill patients have white blood cells and lymphocytes decreased and there is thrombocytopenia; chest imaging: The combined pneumonia lung slice images can be seen. Serious cases, a wide range of sheet images.
5, diagnosed conditions: influenza-like clinical manifestations, while one or more of the following laboratory results:
① Influenza A H1N1 influenza virus nucleic acid testing positive (can use real-time RT-PCR and RT-PCR).
② isolated influenza A H1N1 influenza viruses.
③ Influenza H1N1 influenza virus in serum and in specific antibody levels was four times or four times higher.
Differential diagnosis: It should be noted with the flu, avian flu, the flu, pneumonia, SARS, infectious mononucleosis syndrome, cytomegalovirus infection, Legionella pneumonia, chlamydia, mycoplasma pneumonia, and other identification.

Does the prevention of swine flu vaccine? Got swine flu can be cured?
  At present, China has successfully developed the Influenza A H1N1. As the H1N1 swine influenza virus is different from the H1N1 human influenza virus, the current flu vaccine does not prevent H1N1 swine influenza viruses. However, four kinds of treatment can prevent seasonal influenza, swine influenza drugs: amantadine (amantadine), rimantadine (rimantadine), oseltamivir (oseltamivir) and zanamivir (zanamivir). Despite its treatment of influenza are effective drugs, but recently from the swine flu virus detected in vivo in patients with features of view, it has amantadine (amantadine), rimantadine (rimantadine) have a resistance. Therefore, in the treatment and prevention, the use of oseltamivir (oseltamivir) and zanamivir (zanamivir) will be more effective.
Will a large-scale spread?
Since 1997, H5N1 avian influenza outbreak in Hong Kong, the World Health Organization (hereinafter referred to as WHO) is the first time, flu warning level from three to four. This means that the world must take urgent measures to deal with the challenges caused by swine flu.
The World Health Organization warned that the flu from three to four, has meant that the assessment of risk for influenza occurred in a qualitative change. Because, according to their classification, 1-3 warning, only requires Member States to take preparatory measures, including the strengthening of capacity-building and emergency preparedness measures; but if reached 4-6, then requires States to enter the emergency response state, and take the necessary preventive and control measures.
In nature, the influenza virus has been spread in animals, including birds and pigs. Although in theory, all of which are infected with influenza to human risk, but if not caused by real danger to humanity, warning level was set to 1.
In the two warning stage, domestic or wild animals has caused human infection, poses a potential pandemic threat.
A warning to the three stages of influenza viruses from animals or animal and human influenza re-assigned after the virus has caused sporadic human or small-scale (household level) of infection; but throughout their interpersonal communication abilities, but also unsustainable. Earlier this year, has appeared in China more sporadic cases of H5N1 highly pathogenic avian influenza, at this stage on.
Pregnant women in the disease after contact with sick pigs died. 1976, New Jersey, appeared in a U.S. military base in infectious diseases of swine influenza situation, a sick soldier died and another four soldiers were hospitalized with pneumonia. At first, the experts also fear that this virus is killing millions of lives have been the "Spanish flu" variant, but fortunately did not spread to the base of the virus outside.

Mexico City asks citizens in public places for at least 1.8 meters away from each other.
The swine influenza virus showed a characteristic, that is, strong attack on the young adults, Mexico, confirmed most of the dead were under 25 years of age to 45 years old. Health experts have warned, after the outbreak of influenza is difficult to prevent it from spreading, but common sense can help individuals protect themselves. They pointed out that the most important task is to wash their hands with alcohol hand-washing at the end of milk or foam disinfectant to kill bacteria or virus, the effect is very good. The United States, "Centers for Disease Control" (CDC), Acting Director besser (Richard Besser), said: "when coughing or sneezing, cover, wash hands frequently."
To eat pork swine flu will not spread it? In general, the current does not appear as long as the H1N1 variant, heated to 71 ℃ can be killed, the public do not have to worry about the blind.
Because the H1N1 subtype swine influenza virus antigens to human H1N1 viruses are very different, seasonal influenza vaccine does not provide protection for mankind. In order to prevent infection, should take the following measures:
To keep hands clean and wash hands properly. If not visibly soiled, the alcohol rub can be disinfected.
Avoid hand contact with the eyes, nose and mouth.
Cover nose and mouth when sneezing or coughing.
Do not spit, if we spit should discharge wrap disposed of in a covered rubbish bin.
Symptoms of respiratory tract infection or fever should wear a mask and seek medical advice as soon as possible.
If flu symptoms appear, do not go to work or school.
Such as the outbound or return journey after a fever or flu-like symptoms, medical treatment should be immediately inform the doctor about your travel history.

Influenza viruses also cause cross-species of human infection with swine influenza virus, whose symptoms are similar to ordinary flu, but the severity was very different. Usually a sudden fever to 38 degrees Celsius, cough, headache, joint pain, stuffy nose, malaise and lack of appetite. Number of people infected with the virus will appear runny nose, sore throat, nausea, vomiting and diarrhea. In the past found some of the cases, people also infected with swine influenza pneumonia, respiratory failure occurred, as well as the deterioration of chronic health conditions. And also some patients with no discomfort, while others enough to death. Department of Microbiology, University of Hong Kong Professor Yuen pointed out, swine influenza mainly people with weak resistance to a greater threat. Therefore, as long as maintaining good health, adhere to physical exercise, people do not need to worry too much.
Swine flu spread?
Mexicans take the subway have to wear a mask.
Group of swine influenza infection is spread primarily between coughing and sneezing as a medium, in the crowded environment more susceptible to infection, and more and more evidence shows that micro-virus can be retained on the desktop, telephone, or other flat surface, and then through the fingers and the eyes, nose, mouth contact to spread. So try to avoid physical contact, including shaking hands, kissing, a total of meals. If the contact with the swine influenza virus of items, rather then touching their nose and mouth, will also be infected. Infected before the onset of symptoms may infect other people, usually in a week after infection, or more than a week after the onset. Infectious children will be longer.
Recently, Mexico and the United States a new series of outbreaks of swine influenza virus outbreak in Mexico of up to 4,000 suspected cases, may have been 152 people died of swine flu, the United States has confirmed that 50 people are infected.
