Disease Case Studies Prep Steps Unit 2 Lesson 2 Lesson Questions What steps are involved in viral infection and replication Why are some kinds of influenza virus more deadly than others . While rare influenza can spread from pigs to people and from people to pigs When people get swine flu viruses its usually after contact with pigs This has happened in different settings including fairs Right now the Centers for Disease Control and P 1747 Citadel Plaza • Suite 206 • San Antonio, TX 78209 •(210) 826-0910 •Longhorn-VandD@sbcglobal.net. Background. . Influenza virus: a highly evolving pathogen-. In the US: . 200K hospitalizations, 35,000 deaths per yr. . Les Sims. Asia Pacific Veterinary Information Services. apvis@bigpond.net.au. Background. Animal influenza is not eradicable. Possible to eliminate certain strains of virus. Equine influenza in Australia. September 26, 2012. 1. Why is influenza vaccination being measured among healthcare personnel?. Influenza can be spread by an ill person one day . before. to 7 days . after. onset of symptoms.. Healthcare personnel (HCP) care for, or are in frequent contact with, patients with influenza or at high risk for complications of influenza.. Orthomyxoviridae family of viruses. RNA enveloped viruses that make up three genera. Influenzavirus A. Influenzavirus B. Influenzavirus C. The type A viruses are the most virulent among the three, genetically diverse and infecting human, birds and animals. HIV1 and slower to progress to AIDS.. Most cases are due to type1.. Modes of transmission. 1-sexual.. 2- perinatal.. 3-parenteral(occupational and intravenous drug injection).. 4- blood transfusion.. The Indiana State Department of Health (ISDH) Laboratories maintains a strong relationship with ISDH Epidemiology for year-round surveillance to detect circulating seasonal and novel influenza. As a result of these enhanced surveillance efforts, Indiana was the first state in 2011 to detect cases of human infection with influenza A(H3N2)v virus. Over the years, the Indiana Board of Animal Health (BOAH) and the ISDH have developed a cooperative partnership for enhanced swine influenza (SIV) surveillance. Though BOAH does not perform routine influenza testing for the purpose of surveillance, they maintain constant communication with swine industry stakeholders, such as Indiana swine veterinarians, in order to be alerted when influenza case numbers are higher than normal or otherwise unusual in clinical presentation. . Q&As for health professionals Why did influenza policy change in 2013/14? his year, all healthy children aged two, three and four years, are being offered a vaccination against influenza. This follo to virology. What is a Virus?. Viruses are infectious units with diameters of about 16 nm to over 300 nm (poxviruses). Their small size makes them ultra filterable, i.e. they are not retained by bacteria-proof filters. Viruses have evolved over longtime period, and have adapted to specific organisms or their cells. The infectious virus particles, or . Quan C, Wang Q, Zhang J, Zhao M, Dai Q, Huang T, et al. Avian Influenza A Viruses among Occupationally Exposed Populations, China, 2014–2016.

(or most commonly referred to as flu) in birds, various mammals (such as pigs) and humans. Typically, influenza is characterized by fever, sore throat, chills and other non-specific symptoms, it is a much more severe disease. It is spread around the world in seasonal epidemics and according to World Health Organization, these annual epidemics result in about three to five million cases of severe illness, and about 250 000 to 500 000 deaths..
