Swine flu is an acute, contagious respiratory disease of pigs. It is characterized by sudden onset, coughing, difficulty breathing, fever and rapid regression.
Experts at the U.S. Centers for Disease Control and Prevention explain that swine flu is an acute respiratory infection caused by the swine influenza virus, which occurs frequently in swine but rarely results in death.
Swine influenza (SI) is an acute respiratory infection of pigs caused by influenza A viruses. Influenza viruses belong to the family Orthomyxoviridae, which includes four genera, A, B, C, and Togolovirus spp. Influenza A viruses can infect a wide range of animals, including many avian and mammalian species. B and C viruses appear to have been isolated only from humans, and although influenza C viruses have also been isolated from swine [1], it is mainly the influenza A virus that infects swine. Swine influenza has been reported in the United States, Hungary and China as early as 1918, which coincides with the Spanish human pandemic of 1918. The disease now has a worldwide distribution, but is mainly endemic. SIV infection alone is characterized by high morbidity (100%). The low morbidity and mortality rate (about 5%) is characterized by its severity related to the prevalent strains, the age and health status of pigs, environmental conditions and bacterial secondary infections. Swine influenza not only jeopardizes the health of pigs, but also affects the time to market of fattening pigs and increases the cost of feeding, so the losses caused to the pig industry should not be ignored.
Human swine influenza is a respiratory infectious disease caused by swine influenza virus. People infected with swine flu virus will show flu-like symptoms. The virus is effective with Tamiflu (Oseltamivir) in the early stages of infection, but is resistant to Amantadine (Amantadine) and Rimantadine (Rimantadine). Preventive measures mainly include avoiding contact with influenza-like patients and maintaining personal hygiene, etc. If swine flu infection is suspected after entering the country, one should wear a mask at home or when seeking medical treatment and explain the travel history to the doctor.
Mainstream antiviral drugs are effective against the strain CDC officials pointed out on April 23, 2009, preliminary studies have detected that the pandemic swine influenza virus is an influenza A virus, which carries the H1N1 subtype of swine influenza virus strains, including avian influenza, swine influenza, and human influenza, three influenza viruses deoxyribonucleic acid (DNA) gene fragments, and at the same time, has the characteristics of Asian swine influenza and African swine influenza viruses. It also possesses the characteristics of Asian swine influenza and African swine influenza viruses. Medical tests have shown that current mainstream antiviral drugs are effective against this strain.
Swine flu symptoms Symptoms of swine flu in humans are similar to those of a cold, with patients experiencing fever, cough, fatigue and loss of appetite. In terms of prevention, there is no need to pile on the human flu vaccine at this stage, as the seasonal flu vaccine is not effective in preventing swine flu. The right thing to do is to develop good personal hygiene habits, adequate sleep, exercise, reduce stress, adequate nutrition; wash your hands regularly, especially after touching public **** items to wash your hands before touching your eyes, nose and mouth; sneezing and coughing should be used to cover the mouth and nose with a tissue; indoor ventilation and so on.
Ebola virus, SARS, human avian influenza, swine streptococcal infections, swine flu ...... the above in recent years, the frequent "trouble" diseases, the source of almost all from animals. In recent years, 70% to 80% of the world's new infectious diseases belong to human and animal **** disease, and the incidence of the momentum of the past few years to see the rise.

The swine flu in the United States found cases of the main manifestations of sudden fever, cough, muscle pain and fatigue, some of them also appear diarrhea and vomiting symptoms; Mexico found cases also appear red eyes, headache and runny nose and other symptoms.
There are many triggering factors that cause swine flu to occur and become prevalent, which can be broadly categorized into three areas: first, human factors, second, weather factors, and third, environmental factors.
The incidence of the disease is high, the incubation period is 2 to 7 days, the course of the disease is about 1 week. Sick pigs at the onset of sudden fever, mental instability, loss of appetite or abolition, often lying together, unwilling to move, breathing difficulties, intense coughing, mucus from the eyes and nose. If the treatment is not timely in the morbidity period, it is easy to complicate bronchitis, pneumonia and pleurisy, etc., increasing the death rate of pigs.
