Olsen, DVM PhD, School of Veterinary Medicine and School of Medicine and Public Health, University of Wisconsin-Madison. Reviewers: Jeff B. Bender, DVM MS, University of Minnesota; Andrew Bowman, DVM PhD, The Ohio State University; Todd Davis, PhD, CDC; Ellen Kasari, DVM MS, USDA; Heather Fowler, VMD PhD MPH, National Pork Board Influenza A viruses (IAV) were first isolated from swine in the United States in 1930. Since that time, they remain an economically important cause of respiratory disease in pigs throughout the world and a public health risk. The clinical signs/symptoms of influenza in pigs and people are remarkably similar, with influenza-like illness (ILI) consisting of fever, lethargy, lack of appetite and coughing promi- nent in both species. Influenza viruses can be directly transmitted from pigs to people as “zoonotic” disease agents (pathogens that are transmitted from animals to humans or shared by animals and humans) and cause human infections. Conversely, influenza viruses from people can also infect and cause disease in pigs. These interspecies infections are most likely to occur when people and pigs are in close proximity with one another, such as during livestock exhibits at fairs, live animal markets, swine production barns, and slaughterhouses. Finally, pigs can serve as intermediaries in the generation of novel reassorted influenza viruses since they are also susceptible to infection with avian influenza viruses.

Treatment and Prevention of Pandemic H1N1 Influenza
Annals of Global Health VOL. 81, NO. 5, 2015 ª 2015 The Authors. Published by Elsevier Inc. ISSN 2214-9996 on behalf of Icahn School of Medicine at Mount Sinai http://dx.doi.org/10.1016/j.aogh.2015.08.014 REVIEW Treatment and Prevention of Pandemic H1N1 Influenza Suresh Rewar, Dashrath Mirdha, Prahlad Rewar Rajasthan, India Abstract BACKGROUND Swine influenza is a respiratory infection common to pigs worldwide caused by type Ainfluenza viruses, principally subtypes H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. Swine influenza viruses also can cause moderate to severe illness in humans and affect persons of all age groups. People in close contact with swine are at especially high risk. Until recently, epidemiological study of influenza was limited to resource-rich countries. The World Health Organization declared an H1N1 pandemic on June 11, 2009, after more than 70 countries reported 30,000 cases of H1N1 infection. In 2015, incidence of swine influenza increased substantially to reach a 5-year high. In India in 2015, 10,000 cases of swine influenza were reported with 774 deaths. METHODS The Centers for Disease Control and Prevention recommend real-time polymerase chain reaction as the method of choice for diagnosing H1N1. Antiviral drugs are the mainstay of clinical treatment of swine influenza and can make the illness milder and enable the patient to feel better faster. FINDINGS Antiviral drugs are most effective when they are started within the first 48 hours after the clinical signs begin, although they also may be used in severe or high-risk cases first seen after this time.

Available online 19 October 2011 Swine influenza also called as swine flu, hog flu, and pig flu that refers to influenza is caused by Keywords: those strains of influenza virus, called SI virus (SIV), that usually infect pigs endemically. As of Coughing 2009, these strains are all found in influenza C virus and subtypes of influenza A virus known as Fever H1N1, H1N2, H3N1, H3N2, and H2N3. The viruses are 80–120 nm in diameter. The transmission of H1N1 SIV from pigs to humans is not common and does not always cause human influenza, often only sore throat resulting in the production of antibodies in the blood. The meat of the animal poses no risk of swine flu swine influenza virus transmitting the virus when properly cooked. If the transmission does cause human influenza, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at an increased risk of catching swine flu. In the mid-20th century, the identification of influenza subtypes became possible; this allowed accurate diagnosis of transmission to humans.

Given its importance, we characterized two swine influenza viruses isolated from Shandong, China. The homology and phylogenetic analyses showed that all eight gene segments of A/swine/Shandong/AV1522/2011(H1N1) were closely related to A/Maryland/12/1991(H1N1) circulating in North America. The HA, NA, M, and NS genes of the isolate were also confirmed to have a high homology to A/swine/Hubei/02/2008(H1N1) which appeared in China in 2008, and the virus was clustered into the classical swine lineage. The gene segments of A/swine/Shandong/AV1523/2011(H1N1) were highly homologous to the early human H1N1 and H2N2 influenza viruses, except for the HA gene, and the virus was a reassortant H1N1 virus containing genes from the classical swine (HA) and human (NA, PB2, PB1, PA, NP, M, and NS) lineages.

What People Who Raise Pigs Need to Know About Influenza (Flu)
What People Who Raise Pigs Need To Know About Influenza (Flu) Introduction As someone who raises pigs, whether for show (e.g. 4-H or Future Farmers of America [FFA]) or as part of a farming operation (i.e. commercial pork producer), you may have questions about influenza (the flu) in both pigs and people. This document addresses what is known about flu viruses in pigs and people and what people in contact with pigs can do to reduce the risk of getting sick or of getting their pigs sick. Influenza Virus Infections in Pigs There are many causes of respiratory disease in pigs, including influenza. Among influenza types, only type A influenza viruses are known to infect pigs. Although pigs and people now share the H1N1 pandemic virus, other viruses circulating in swine are different from viruses circulating in people. At this time, there are three main flu A viruses that circulate in U.S. pigs: influenza A H1N1, influenza A H1N2 and influenza A H3N2. These viruses do not usually infect people and are genetically different from the H1N1 and H3N2 viruses that commonly circulate in people. When swine flu viruses are very different from the human flu viruses causing illness in people, people may have little to no immune protection against these swine viruses. Also human flu vaccines probably would not offer protection against the viruses that are found in pigs. Flu viruses commonly infect pigs and pig herds and can result in high rates of illness among pigs, but few deaths. Signs of influenza in pigs include: • Coughing (“barking”) • Breathing difficulties • Sneezing • Discharge from the nose • High fevers • Going off feed However, pigs also may become infected with flu viruses from people, and from birds.

VOL. 1, NO. 1 AUGUST, 1999 SWINE FACT SHEET Authors: Swine Influenza Virus Sabrina L. Swenson, DVM, PhD 1 Gene A. Erickson, DVM, PhD 2 NATIONAL PORK PRODUCERS COUNCIL Background: Swine influenza virus (SIV) infections in swine are common causes of respiratory disease in pigs. Infection of pigs occurs throughout the world. Prior to 1998, swine influenza in pigs P.O. BOX 10383 in the United States was caused by H1N1 SIV. In August of 1998, a North Carolina herd exhibiting DES MOINES, IA 50306 515 223 2600 clinical signs of influenza was identified with H3N2 SIV. Since that time, isolates from pigs in Texas, FAX 515 223 2646 Iowa, Minnesota, and Illinois have been typed as H3N2 SIV. [email protected] Etiology: Swine influenza virus is an orthomyxovirus with a segmented RNA genome. Orthomyxoviruses are divided into three groups as type A, type B, or type C. Only type A viruses infect pigs. The type A viruses are further subtyped based on their hemagglutinin (H) and neu- raminidase (N). There are 15 hemagglutinins (H1-H15) and 9 neuramindases (N1-N9) that have been identified in humans, animals, and birds. Due to the segmented genome, genetic reassortment can AMERICAN occur between different subtypes, resulting in antigenic shift when H and N genetic material are ASSOCIATION OF SWINE exchanged between viruses.

However, the rapidly mutating viruses and development of new strains make it necessary to develop new influenza vaccines annually. Hence, vaccines that stimulate cross-protection against multiple influenza subtypes are highly sought. Recent evidence suggests that adjuvants such as PCEP that promote Th1-type T cell and Th2-type T cell immune responses and broad-spectrum immune responses may confer cross-protection against heterologous influenza strains. In this study, we evaluated whether the immunogenic and protective potential of PCEP-adjuvanted inactivated swine influenza virus H1N1 vaccine can protect pigs immunized against live H3N2 virus. Piglets were vaccinated via the intradermal route with PCEP-adjuvanted inactivated swine influenza virus (SIV) H1N1 vaccine, boosted at day 21 with the same vaccines then challenged with infectious SIV H3N2 virus at day 35 via the tracheobronchial route.

Key Facts About Human Infections with Variant Viruses
Key Facts about Human Infections with Variant Viruses Questions & Answers This page contains background information about swine influenza virus infections in humans, now called “variant virus infections in humans.” What is Swine Influenza? Swine influenza (swine flu) is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Swine flu viruses can cause high levels of illness in swine herds, but usually cause few deaths. Common signs in sick pigs include fever, depression, coughing (barking), discharge from the nose or eyes, sneezing, breathing difficulties, eye redness or inflammation, and going off feed. However, influenza-infected pigs also may not appear ill or be only mildly ill. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks of seasonal influenza in humans. What is a variant influenza virus? When an influenza virus that normally circulates in swine (but not people) is detected in a person, it is called a “variant influenza virus.” For example, if a swine origin influenza A H3N2 virus is detected in a person, that virus will be called an “H3N2 variant” virus or “H3N2v” virus. This naming convention was first announced in a January 6, 2012 Morbidity and Mortality Weekly Report entitled Update: Influenza A (H3N2)v Transmission and Guidelines — Five States, 2011. (See Box) Can humans be infected with swine influenza viruses? Yes. Swine flu viruses do not normally infect humans, however, sporadic human infections with influenza viruses that normally infect swine have occurred.
