Type a H 1N 1Meeting 5 can infect more animals than people?

Yes! Similar to other flu symptoms, such as high fever, cough, fatigue, anorexia and so on. Another report said that the cases found in the United States were mainly characterized by sudden fever, cough, muscle pain and fatigue, and some of them also had symptoms of diarrhea and vomiting; Mexico has also found symptoms such as red eyes, headache and runny nose. At present, the symptoms of Xi 'an may appear only after this new swine flu virus has been lurking in the human body for 7 days. The US Centers for Disease Control and Prevention confirmed that the swine flu virus that killed dozens of people in Mexico and the virus that infected dozens of people in the United States were both A/H 1N 1 type. However, the cases in the United States are relatively minor and there are no deaths. What are the characteristics of this epidemic? WHO emphasizes that children and the elderly are usually more susceptible to influenza virus, but most of the people infected with swine flu virus in Mexico this time are young people and need special attention. Do you have a swine flu vaccine? Although there is no vaccine to prevent people from contracting swine flu, it can be prevented, controlled and treated. According to the CDC, there are four commonly used anti-influenza drugs, but there are two kinds of this mutant virus in clinic. At present, the known epidemic areas of human swine flu are California, Texas and Kansas, as well as Mexico City, Oaxaca in the southeast, San Luis Potosi in the middle and sicali in the north, and Baja California. It is suggested that China citizens should know about the progress of local epidemic situation and take personal protection when they travel to the above areas for business and tourism. Pathological changes of swine flu are mainly in respiratory organs. The mucosa of nose, pharynx, larynx, trachea and bronchus is congested and swollen, and the surface is covered with viscous liquid, and bronchioles and bronchioles are filled with foam-like exudates. A large amount of slurry mixed with cellulose was accumulated in the chest cavity and pericardium cavity. Pulmonary lesions often occur in the back and base of the cusp, heart, middle leaf and diaphragm, and have obvious boundaries with surrounding tissues. The color is from red to purple, it collapses and is strong, and its toughness is like leather. Spleen enlargement, cervical lymph nodes, mediastinal lymph nodes and bronchial lymph nodes are swollen and juicy. What preventive measures are there? Influenza virus is mainly transmitted through air and contact. Cover your nose and mouth when coughing or sneezing. Because the flu virus can often live on the surface of some daily necessities for a period of time, Qin Ying washes his hands and often disinfects daily necessities with alcohol. In addition, "getting together" in crowded places is also an effective way to reduce the probability of infection. Finally, if the patient is found to be infected, he should try to avoid going out to prevent the virus from spreading to others. Animal husbandry and veterinary experts pointed out that summer and autumn are the high incidence seasons of swine flu, and if the prevention and control is not good, it is likely to lead to the disease. There are many inducing factors leading to the occurrence and prevalence of swine flu, which can be roughly summarized into three aspects: one is human factors, the other is weather factors, and the third is environmental factors. Rough feeding management leads to diseases: in the busy farming season of summer harvest and autumn harvest, farmers pay attention to crops in the fields and ignore the pigs in the pens, fail to vaccinate the pigs in time, fail to feed the pigs in time, make the pigs hungry, and fail to clean the pens in time, all of which will lead to diseases. Free-range households in many areas of our city raise pigs in low, damp, poorly ventilated, dirty and muddy pig houses. Pigs can't escape the cold rain in hot summer, and they can't escape the bite of blood-sucking insects. In addition, they were fed spoiled swill feed. How can pigs not get sick? Inadequate epidemic prevention leads to illness: In recent years, in the process of institutional reform in many areas, rural grass-roots animal husbandry and veterinary stations have been abolished or merged, which has broken the network of grass-roots veterinary service system, resulting in paralysis or semi-paralysis of animal epidemic prevention, resulting in the situation that pigs and poultry are not vaccinated and no one is engaged in quarantine in the production area, leading to the onset of swine flu. Farmers irrigate their own veterinarians to brew bitter fruit: in quite a few areas, it is common for farmers to irrigate their own veterinarians. With a little knowledge of animal disease prevention and control, they bought syringes and commonly used drugs, and gave injections to pigs without eating. Most of them don't know the immune procedure, diagnosis and medication mechanism. When they find that animals are seriously ill, they often panic and then go to the vet for treatment. This operation not only can't prevent diseases, but also pig diseases often occur all year round. Free slaughter leads to a vicious circle: many farmers sell sick pigs to kitchen knives at low prices when they see that they have not improved after several injections. Knives sell sick pork in the market, which makes the disease spread in a wider range. For example, the restaurant will return the swill containing pathogenic bacteria (virus) to the suburban countryside (urban-rural fringe) to feed pigs, resulting in more pigs getting sick. This has formed a vicious circle, which often makes the epidemic of diseases repeated or one after another, and can not be controlled for a long time. According to the investigation of swine flu epidemic situation in recent years, swine flu is often the forerunner in summer and autumn, which in turn leads to many complications and secondary diseases, such as swine fever, pig lung disease, piglet paratyphoid, contagious pleuropneumonia and streptococcus suis. Among them, the most easily complicated or secondary is porcine contagious pleuropneumonia. According to the investigation, influenza is often the chief culprit of pig diseases in summer and autumn in a region. Diseases that come first and then come second or complicated often complicate the disease and bring high morbidity, mortality and elimination rate to pigs. Disinfection is imminent. How to prevent the outbreak of swine flu? Animal husbandry and veterinary personnel pointed out that the temperature is high in summer and autumn, and disinfection in high temperature season can get twice the result with half the effort. Veterinary epidemic prevention institutions at the county and township levels should make full use of the high temperature season, organize farmers to carry out disinfection and source eradication activities, and effectively eliminate pathogens. Relevant departments should strictly enforce the law, severely crack down on indiscriminate slaughter, prohibit the sale and slaughter of sick pigs, and prevent the spread of epidemics. At present, all localities should implement the State Council's Opinions on Promoting the Reform of Veterinary System, improve the animal epidemic prevention service system, seriously fill the current epidemic prevention gap, and earnestly do a good job in animal epidemic prevention.
