Infectious Diseases And Its Effects On The Health Of Chickens

Introduction This written report will cover both infectious and non-infectious diseases and their effects on the health of chickens. Causes of each disease will be explained along with symptoms and clinical signs that may occur during the onset of disease. This report will explain the treatment and prevention for the diseases chosen and any management strategies in place to control the disease. Infectious Diseases Newcastle Disease Virus (NDV) (Avian pneumoencephalitis) Newcastle Disease Virus is an infectious disease of poultry and fowl caused by the virus, ‘Paramyxovirus’ serotype 1 (Foster and Smith, 2017a); (Alexander, 2000). The severity of this virus depends on the susceptibility of the host and how virulent the virus is. Chickens†¦show more content†¦Treatment, Prevention and Control There is currently no treatment for Newcastle Disease Virus, however in some cases hyper-immune serum injections have been used on exposed birds that are not showing symptoms (Foster and Smith, 2017a) and antibiotics are occasionally given to prevent secondary infections (Jacob, 2015a). Due to NDV being highly contagious and severe it is classed as a notifiable disease, therefore any bird showing symptoms of this disease must be reported to the Animal and Plant Health Agency where action will be taken to prevent the disease from spreading (DEFRA, 2014b). Vaccinations can be administered to protect birds against clinical signs and decrease the risks of contracting the virus (CFSPH, 2016). Strict biosecurity practices and correct husbandry are also vital in the prevention of NDV, this includes the isolation of any outbreaks, disposal of any infected carcasses, thorough cleaning and disinfection (Beautyofbirds, 2017); (DEFRA, 2014a). Fowl Cholera (Avian Pasteurellosis) Fowl cholera is a contagious bacterial disease seen in captive and wild fowls caused by ‘Pasteurella multocida’ to which domestic poultry; such as chickens, are particularly susceptible (West, 1976b); (Christensen, 2016) causing high morbidity and mortality and bacteraemia (OIE, 2016). Overcrowding, climate and stress are a few known environmental factors said to have an effect the severity of theShow MoreRelatedEpidemiology-Chickenpox1582 Words   |  7 PagesEpidemiology Paper- Chicken Pox Grand Canyon University Community/Public Health Nursing NRS-427V August 8, 2015 Chicken Pox or Varicella is a highly contagious viral disease caused by the Varicella-Zoster virus that causes a blister like itchy rash all over the body. The rash is the disclosing indication of chicken pox (Mayo Clinic 2015). While signs and symptoms of chicken pox will usually appear one to two days prior to the rash, the rash itself will last from five to ten days. The symptomsRead MoreDisadvantages Of Vaccination1517 Words   |  7 PagesImmunisations against various diseases benefits the wider population. Discuss. Immunisations made a debut to the world in the early 1800’s after Edward Jenner created the smallpox vaccination. Vaccine can be defined as a product containing dead or weakened antigens of a specific disease so that the body’s immune system is able to recognise the disease.1 The term immunisation can be defined as the administration of a vaccine to stimulate the body’s natural immune system to build resistance as wellRead MoreWhy Vaccination Should Be Mandatory875 Words   |  4 Pagesever since the original smallpox vaccine over two centuries ago. Parents, teachers, children and health care specialists all have a vital stake in this debate. Parents believe they should have the right to make the decision on whether or not to vaccinate their children. While health care officials disagree, claiming that by not vaccinating, all children will be susceptible to the vaccine-preventable diseases. Megan Heimer discusses the risk of vaccinating a child and that it shoul d not be mandatory inRead MoreVaccination Of Children And Children1730 Words   |  7 Pageshas a different immune system and reacts to illnesses differently. Imagine having a child with disabilities and having them around children that have not been vaccinated. With the poor immune system autistic kids have they would be catching every disease possible. Autism is a condition typified by abnormal qualitative development of social interactions, communication and imagination, with restricted and repetitive interests and activities (Edward Purssell RGN, RSCN, PhD of the University of London)Read MoreCompulsory Vaccinations And The Public Health Intervention Essay1324 Words   |  6 PagesAs large as the controversy is when it comes to compulsory vaccinations, the public health intervention will always have negative or harmful effects in combination with the benefits of compulsory vaccinations. For those that stand behind the argument that immunizations are unnecessary in our children, have argued that the vaccine industry has misrepresented the safety of vaccines. They also have argued that they have covered up information regarding certain vaccinations to gain from the financialRead MoreEssay On Vaccination1027 Words   |  5 Pagesthe American Public Health Association said, â€Å"Because of their impact on society, a coordinated strategy is necessary to understand, detect, control, and ultimately prevent infectious diseases† (Williams 10). Mandatory vaccinations will insure the protection of health, diseases would eventually become eradicated, and people would no longer be able to spread diseases throughout the world. Vaccinations are a way to protect people from the harmful effects of contagious diseases. Vaccinations are aRead MoreThroughout Our History, Infectious Diseases Have Posed1636 Words   |  7 PagesThroughout our history, infectious diseases have posed the biggest challenge on human survival. It’s hard to believe that people once assumed that foul odors caused diseases or that one becomes ill due to the presence of â€Å"evil spirits†. It’s also hard to imagine that there was a time in which it was seldom that a parent would see all of their children grows up into adulthood. The fight against disease developed with the consolidation of the germ theory, which also offered a massive forewarning forRead MoreEpidemiology of Chickenpox1614 Words   |  7 Pagesbetter understanding of the disease.

Also, th e reader will become familiar with the determinants of health and contributing factors to develop varicella, the relation of the epidemiologic triangle, the role of the community health nurse, as well as identify a national organization that reduces the impact of the disease on the community.

From its inception of 1918, influenza claims an average of 250,000 to 500,000 people worldwide, annually. Little is known of the virus’s
