Will swine flu be introduced to China?

There are already suspected cases in Hong Kong, and now that the economy is globalized, it is very likely to be transmitted to China, and it is necessary to strengthen the detection of people and things entering China, and now it is not called swine flu, it is called H1N1 hope.

Swine flu is an acute respiratory infection caused by the swine flu virus, but it is rarely transmitted to humans. The patients in this outbreak are infected with a new strain of H1N1 subtype swine influenza virus, which contains gene fragments of **susceptible virus, North American avian influenza virus, and three types of swine influenza viruses in North America, Europe, and Asia. The virus has been confirmed to be transmitted from person to person, and people who are infected will have symptoms such as high fever, lack of energy, anorexia, and cough.

Scientists point out that sneezing, coughing and physical contact could all contribute to the spread of the new swine flu virus among people. Another major feature of the swine flu virus is that it is highly aggressive to young adults, and most of the confirmed swine flu deaths are between the ages of 25 and 45. However, scientists pointed out that the swine flu virus can be prevented and controlled, and the existing drugs of the common influenza virus are equally effective in preventing and treating this swine flu virus.

The U.S. Centers for Disease Control and Prevention specifically states that people cannot get swine flu from eating pork or pork products, and that pork can be heated to 71 degrees Celsius to kill the swine flu virus.

It is not ruled out that China will be infected with swine flu Symptoms: Similar to a cold, fever, cough, fatigue, loss of appetite, etc. • Fast transmission: The human body has no natural antibodies to the new mutant virus • Mode of transmission:

Sneezing, coughing, and physical contact • Susceptible population: mostly young adults, not the elderly and children • Prevention: Get enough sleep, exercise frequently, wash hands frequently, keep indoor ventilation, etc., and develop good personal hygiene habits.

**: Tamiflu (oseltamivir) is effective in the early stage of infection Therefore, personal hygiene is the most important.

Respiratory transmission.

Swine flu is an acute, infectious respiratory disease in pigs. It is characterized by suddenness, cough, dyspnea, fever, and rapid regression.

Key points of diagnosis: Epidemiological characteristics: Pigs of all ages, sexes, and breeds are susceptible to the virus. The epidemic of the disease is significantly seasonal, with the weather prone to late autumn, early spring, and cold winters. The disease spreads rapidly and is often endemic or pandemic.

It has a high incidence and a low mortality rate (4% to 10%). Sick pigs and pigs with poison are the source of infection of swine flu, and pigs are infected for 6 to 8 weeks after the disease is cured.

Clinical featuresThe incubation period is short, ranging from a few hours to a few days, with an average of 4 days at the time of natural onset. In the early stage of the disease, the body temperature of the sick pig suddenly rises, anorexia or appetite is lost, extremely weak and even collapse, and often lie on the ground. Shortness of breath, abdominal breathing, paroxysmal cough.

Mucus flows from the eyes and nose, and nasal discharge is sometimes bloody. Sick pigs are crammed together, difficult to move, and the muscles are stiff and painful to touch, and diaphragm spasms and breathing are frustrated, which is generally called hiccups. If there is a secondary infection, the disease worsens, and fibrinous hemorrhagic pneumonia or enteritis develops.

Sows are infected during pregnancy, and piglets are severely ill 2-5 days post-farrowing, and some die during lactation and around weaning.

Pathological changes: The pathological changes of pig epidemic are mainly in the respiratory organs. The mucous membranes of the nose, pharynx, larynx, trachea, and bronchi are congested and swollen, covered with viscous fluid, and filled with foamy exudate in the small bronchi and bronchioles. The thoracic cavity and pericardial cavity accumulate large amounts of serous fluid mixed with cellulose.

Lesions of the lungs often occur in the dorsal and basal base of the apical lobe, heart lobe, middle lobe, and diaphragm, with obvious boundaries with the surrounding tissues, the color is from red to purple, collapsed, solid, tough like leather, the spleen is enlarged, and the cervical lymph nodes, mediastinal lymph nodes, and bronchial lymph nodes are swollen and juicy.

Differentiation of Diseases Because the epidemic of pigs does not always appear in a typical form and is very similar to other respiratory diseases, the clinical diagnosis can only be presumptive. In autumn or early winter, respiratory diseases in the herd can be suspected as a pig epidemic.

The outbreak of upper respiratory tract syndrome, including conjunctivitis, sneezing and coughing, and low mortality, can distinguish pig epidemic from other upper respiratory tract diseases in pigs, and in the differential diagnosis, attention should be paid to the difference between pig asthma and this disease, which is most likely to be confused.

Prevention and control measuresThere is no effective vaccine and special effect for this disease**, it is important to take good care and keep the pig house clean, dry, warm and free of thieves. Provide sufficient clean drinking water, ** for the first few days, the feed supply should be limited. Sick pigs should not be harassed or moved during the onset of illness to reduce death from stress.
