How to Treat Swine Flu: Isolation, Care, and Symptomatic Medication Are Key

Swine flu is an acute respiratory infectious disease in pigs caused by influenza A virus. It is highly contagious and spreads quickly, and often occurs when temperatures change suddenly, pens are damp, or stocking density is too high. Affected pigs mostly show sudden fever, depression, coughing and sneezing, rapid breathing, and reduced appetite. The mortality rate in most cases is not high, but it clearly affects growth and is prone to secondary bacterial infection, so it requires attention.

At present, there is no specific drug against swine influenza virus, and treatment is mainly symptomatic and supportive. After sick pigs are found, they should be isolated promptly, the pens should be kept warm, dry, and well ventilated, clean drinking water and easily digestible feed should be provided, and electrolytes and vitamins should be supplemented when necessary. For pigs with obvious high fever or respiratory symptoms, antipyretic and analgesic drugs can be used under the guidance of a veterinarian; if secondary bacterial infection is confirmed, antibiotic treatment should also be used, and the dosage and course of treatment should follow medical advice, avoiding blind overuse.

Beyond treatment, prevention should be done even more thoroughly. Influenza vaccination can be carried out under the guidance of a veterinarian according to local epidemiological conditions, and self-breeding and self-raising should be maintained, with strict quarantine for introduced breeding stock. Pens should be disinfected regularly, and attention should be paid to cold protection, warmth, and ventilation, while stress factors such as transport and feed changes should be minimized as much as possible. If a large-scale outbreak of fever and coughing occurs in the herd, a veterinarian should be called promptly for diagnosis, and it should be distinguished from other respiratory diseases such as classical swine fever and swine pasteurellosis. Do not judge and medicate on your own, lest delayed treatment cause greater losses.
