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. .

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.

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."

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.

H is known as red blood cell agglutinin, N is called neuraminidase, which are glycoproteins located in the virus surface. H are 1-15 subtypes, N there are 1-9 subtypes (in the case of influenza A virus). Due to a combination of H and N are different toxicity and spread the virus is not the same.
1918 ~ 1920, a pandemic of this epidemic first appeared in the eastern United States in January 1918, in April 1918 are popular in the French Army, after the rapid spread of global consequences. The pandemic is known as the greatest plague in human history, resulting in the total number of deaths estimated to be about 50 million people. With regard to the pandemic pathogen, according to serological traceability that is a swine Hsw1N1 (H1N1) influenza virus.

It is the virus structure is spherical or filamentous form. Limited experience in clinical isolates of the laboratory process and tissue culture, there are more filamentous than spherical particles, but mainly spherical particles.
In the H1N1 virus genome contains eight monomers (non-matching) RNA chain code for 11 proteins (HA, NA, NP, M1, M2, NS1, NEP, PA, PB1, PB1-F2, PB2). The total genome size is 13588. Divided nature of the genome to allow the entire gene in cells of different viral vectors exist. 8 RNA, in part:

H1N1 is a virus, is a virus, Orthomyxoviridae family. It hosts are birds and some mammals. Almost all of the H1N1 influenza virus has been isolated, wild birds, the emergence of diseases are rare. Some of severe disease caused by H1N1 virus occurred in poultry in most, but humans are rare. However, after the spread of birds and mammals, and mutation, which may lead to large-scale influenza outbreak or human transmission [1].
H1N1 was also the same series with the H5N1, H7N2, H1N7, H7N3, H13N6, H5N9, H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, H12N5 and so on.

Bacterial and viral respiratory tract infection is quite similar clinical symptoms. The following six aspects of bacterial and viral respiratory infections difference.
1, epidemic viral respiratory tract infection with a significant group of disease characterized by the short term, a majority of human cases, or a people Several human cases; and bacterial respiratory infections Zeyi more common sporadic, the patient little or no side At the same time the sense of fever patients.

1, viral influenza is commonly caused by a variety of viral respiratory infection. Incentives are catch cold, rain, fatigue, malnutrition.
2, mainly as sneezing, nasal congestion, runny nose, throat, sore throat, cough, hoarseness and other symptoms. Manifested as headache, whole body aches, fatigue, weakness, loss of appetite and other symptoms.

Cold, habits divided into viral and bacterial cold cold. Or the common cold and influenza.
Viral cold are: common cold, influenza and viral pharyngitis and so on.
