Swine Flu Virus Infections in Pigs Swine influenza is a respiratory disease of pigs caused by type A influenza viruses and has a major economic impact on the swine industry in the United States. Flu outbreaks in pigs are common, especially during winter months. Swine flu can result in high rates of illness in herds. Flu Can Spread from Pigs to People and from People to Pigs 1.Swine flu viruses can infect humans, but this is not common. 2.Human and swine flu viruses are different. People who get vaccinated for human flu can still get sick from swine flu. Pigs that have been vaccinated for swine flu can still get sick from human flu. 3.Symptoms of swine flu in people are no different from symptoms that people get when they are infected with human flu viruses. 4.People infected with flu typically have fever (often high), cough, body aches, headaches, fatigue and runny or stuffy nose. Vomiting and diarrhea may also occur. 5.Recent studies have shown that 15% to 25% of swine farmers might have been infected with swine flu viruses, as well as about 10% of veterinarians. 6. Cases of swine flu have most commonly occurred in people with direct exposure to pigs, but some cases of human-to-human transmission have been reported.
