How Many Days Does Swine Flu Take to Heal? Detailed Explanation of Medication and Prevention Methods
Swine flu generally refers to swine influenza, an acute, contagious respiratory disease of pigs. It is characterized by sudden onset, coughing, difficulty breathing, fever and rapid recovery. So how many days does it take for a pig to recover from the flu? What medicine is used? How is it prevented and treated?
How many days does it take for a pig to recover from the flu? What medicine is used?
1. The incidence of swine flu is high, the incubation period is 2 to 7 days, and the course of the disease is about 1 week. In the early stage of onset, sick pigs suddenly develop fever, are listless, have reduced or lost appetite, often lie side by side together, are unwilling to move, have difficulty breathing, cough violently, and discharge mucus from the eyes and nose. If treatment is not timely during the onset period, it is easy to develop complications such as bronchitis, pneumonia and pleurisy, which increases the mortality rate of pigs.
2. Its incubation period is very short, from a few hours to several days, with an average of 4 days when the disease occurs naturally. In the early stage of onset, the body temperature of sick pigs suddenly rises to 40.3 to 41.5°C, they refuse to eat or lose their appetite completely, are extremely weak or even collapse, and often lie on the ground. Breathing is rapid, abdominal breathing occurs, and there are paroxysmal coughs. Mucus flows from the eyes and nose, and the nasal secretions are sometimes bloody. Sick pigs huddle together, are difficult to move, and their muscles feel stiff and painful to the touch; spasms of the diaphragm occur, with interrupted breathing, commonly called hiccups. If there is secondary infection, the condition worsens, and fibrinous hemorrhagic pneumonia or enteritis occurs. If a sow is infected during pregnancy, the piglets born develop severe disease 2 to 5 days after birth, and some die during the suckling period and around weaning.
How is swine flu prevented and treated?
Influenza (also called swine influenza) is an acute, contagious respiratory disease caused by type A influenza virus. It is characterized by sudden onset, coughing, difficulty breathing, fever and rapid recovery. It usually breaks out among pigs, is highly contagious, and can cause death. It occurs frequently in autumn and winter, but can spread throughout the year.
1. Epidemiological characteristics: Pigs of all ages, sexes and breeds are susceptible to this virus. The epidemic of this disease has obvious seasonality, and it is prone to occur in late autumn with changeable weather, early spring and cold winter. The disease spreads rapidly and often appears as an endemic epidemic or pandemic. The incidence of this disease is high, and the mortality rate is (4% to 10%). Sick pigs and virus-carrying pigs are the source of infection for swine flu, and pigs carry the virus for 6 to 8 weeks after recovery.
2. Clinical symptoms: The incubation period of this disease is very short, from a few hours to several days, with an average of 4 days when the disease occurs naturally. In the early stage of onset, the body temperature of sick pigs suddenly rises to 40.3°C to 41.5°C, they refuse to eat or lose their appetite completely, are extremely weak or even collapse, and often lie on the ground. Breathing is rapid, abdominal breathing occurs, and there are paroxysmal coughs. Mucus flows from the eyes and nose, and the nasal secretions are sometimes bloody. Sick pigs huddle together, are difficult to move, and their muscles feel stiff and painful to the touch; spasms of the diaphragm occur, with interrupted breathing, commonly called hiccups. If there is secondary infection, the condition worsens, and fibrinous hemorrhagic pneumonia or enteritis occurs. If a sow is infected during pregnancy, the piglets born develop severe disease 2 to 5 days after birth, and some die during the suckling period and around weaning.
3. Prevention and treatment measures: There is no effective vaccine or specific therapy for this disease. What matters is good care and keeping the pigpen clean, dry, warm and free from drafts. Provide sufficient clean drinking water, and in the first few days of recovery, feed should be restricted. Promptly detect and isolate sick pigs, and strengthen disinfection. At the beginning, sick pigs should be given amoxicillin + amantadine + Qingwen Baidu San mixed into the feed. If the symptoms are mainly in the respiratory tract, then florfenicol + azithromycin + amantadine + multivitamins can be mixed into the feed. For pigs that do not eat feed, drugs can be injected intramuscularly to help them start eating, and an antipyretic such as analgin can also be used. If the body temperature is too high and remains persistently high, dexamethasone sodium phosphate 5 to 12 mg, or compound aminopyrine 5 to 10 mL can be injected intramuscularly. Recommended traditional Chinese medicine formula: honeysuckle, forsythia, astragalus, bupleurum, burdock seed, dried tangerine peel and licorice 10 to 16 grams each, decocted in water, taken once a day for 3 consecutive days. Or use bupleurum 6 grams, fangfeng, dried tangerine peel and mint 18 grams each, gaoben, poria peel and bitter orange 12 grams each, chrysanthemum 15 grams, perilla 16 grams, with ginger as a guide, decocted in water.
