There have been documented cases of multiple people becoming sick after exposure to one or more infected pigs and also cases of limited spread of variant influenza viruses from person to person. Human infections with a non-human influenza virus should be fully investigated to be sure that such viruses are not spreading in humans in an efficient and ongoing way, and to limit further exposure of humans to infected animals if infected animals are identified.

At this time, the epidemiology of the human infections reported this week seems consistent with what has been in the past. None of the most recent infections were hospitalized and there were no deaths.

CDC is conducting laboratory studies to find out more about these viruses. Agricultural fairs take place across the United States every year, primarily during the summer months and into early fall.

Many fairs have swine exhibitions, where pigs from different places come in close contact with each other and with people. These venues may magnify the risk of spread of influenza viruses between pigs and people.

The number of variant virus infections reported in humans has varied from season to season. During the summer of , human infections with H3N2v viruses were detected. Subsequently 19 infections of H3N2v were detected in , and only 3 infections each were detected during and Some people are at high risk of developing serious illness from variant virus infections, just as they are from seasonal influenza.

This includes young children, people with underlying health conditions like asthma, diabetes or heart disease, pregnant women and people who are 65 and older. Working with your veterinarian should be a priority to establish the health status of each farm and design a prevention and treatment protocol. Dusan Petkovic, istockphoto.

The symptoms of this disease are skin lesions, caused by an infection of the bacteria Staphlococcus hyicus. In severe cases, mortality can occur, as the bacteria damage the liver and kidneys. Lesions first present as dark areas of skin, which spread and become flaky with a greasy feel.

Antibiotics are used to treat the infection, along with skin protectants; autogenous vaccines have also been used with success. Improving hygiene in piglet housing is key to preventing this condition, along with teat dipping of sows pre- and post-farrowing. It is also important to reduce the potential for skin abrasions, as this is how the infection enters the body. Abrasions are caused by rough floors, jagged teeth, sharp equipment or even mange mites bites.

This disease is very common in suckling piglets and is caused by three types of the intracellular parasite coccidia. It causes diarrhea, which can be bloody, often between 10 and 21 days of age and up to 15 weeks of age. Acute cases are treated with fluid therapy and coccidiostats. Secondary infections can result from damage to the intestinal wall. Depending on the level of occurrence on the farm, preventative treatment of sows with coccidiostats may be appropriate.

Hygiene should be improved to end the cycle of infection; sow feces are a major source, and flies can spread infection. Providing a warm, dry, clean creep area will help to reduce the parasite load and the likelihood of coccidial infection.

Coughing, sneezing, abdominal breathing, reduced growth rates and potentially mortality are all signs of respiratory disease. Diseases in the first category can be costly, but the losses are limited rather than ongoing. They include swine influenza Influenza A Virus in Swine Swine influenza is a highly contagious respiratory disease that results from infection with influenza A virus IAV. IAV causes respiratory disease characterized by anorexia, depression, fever The causal viruses may persist in a herd, but outbreaks of overt disease tend to be self-limiting.

The most important syndromes in the second category are mycoplasmal pneumonia Mycoplasmal Pneumonia in Pigs Mycoplasma hyopneumoniae is a common cause of pneumonia in pigs worldwide. It also frequently leads to subclinical infection that causes lung lesions that can be detected post-mortem.

Clinical signs include fever, anorexia, reluctance to move, respiratory distress, and sudden death Atrophic rhinitis Atrophic Rhinitis in Pigs Atrophic rhinitis is caused by infection with toxigenic Pasteurella multocida.

Signs include coughing, sneezing, and in severe cases, nasal bleeding and poor growth. Diagnosis is based on clinical
