Swine cholera is a viral disease that can cause fever, diarrhea, vomiting, seizures, and death in pigs. It poses an economic risk to the pork industry, and countries may require measures such as killing an entire herd. Vigilance by pig farmers is necessary to prevent the spread of the disease, which can be transmitted directly or indirectly. The disease can occur in several forms, including mild, chronic, and acute, with the acute form being the most severe and fastest-acting.
Swine cholera, or swine fever, is a disease that can infect pigs. This viral disease can cause symptoms such as fever, diarrhea, vomiting and seizures and can lead to death. Many countries take swine cholera seriously due to the economic risk it poses to the pork industry. Therefore, some countries may require measures such as killing an entire herd where an infected pig is found. In countries where the disease has been eradicated, import restrictions, such as a quarantine period, may apply to keep the disease out of the country.
The potential impact of swine cholera requires close vigilance by pig farmers. If a farmer suspects his pigs have the disease, he should act quickly to prevent it from spreading. Infected pigs may appear listless and fatigued and may stop eating, run a fever and have coordination problems and seizures. The disease can occur in several forms, including mild, chronic, and acute. Each of these forms is highly infectious and dangerous to pigs.
The mild form of swine cholera can be the most difficult to detect. Pigs may get sick for a short time, but then they seem to get better. With an infected boar, the virus can remain and proliferate in its reproductive tract. An infected sow may have small litters or stillborn piglets. After a while, the infected pig will often relapse and die.
An acute infection is the most severe and fastest-acting form of swine cholera. Within two weeks of being infected, the pig can die. Symptoms of acute swine fever include fever between 105°F (about 41°C) and 107°F (about 42°C), lack of food, vomiting, and diarrhea. Pigs may also huddle or have trouble walking. Eye problems can also result.
The chronic form of swine cholera is very similar to the acute version, but progresses more slowly. A pig with this form of the disease can be alive for several months before dying. In addition to other symptoms, a pig may also develop red patches on its abdomen, ears and muzzle.
Pork cholera can be transmitted directly from an infected pig to a healthy one. Indirect infections can manifest in a variety of ways, including clothing, equipment, food, and water, as well as infected feces or other bodily fluids. An infected mother can also transmit the disease to her piglets in utero, sometimes resulting in the death of the piglet. Piglets can also be born apparently healthy, but they can still carry the virus and transmit it before they die.
