Chronic & Communicable Diseases Objectives Discuss & give examples of chronic diseases. Define communicable diseases & explain their significance. Discuss disease transmission. Explain how communicable disease is transmitted by: a. intestinal discharges. b. nose & throat discharges. c. zoonoses (animals) Discuss the disease spread by vectors and their control measures.

progression to symptomatic disease when adults are infected. What does “communicable” mean? Can this bacteria be passed through fomites? An infectious disease who’s pathogens passed from one human to another are called infections‚ transmissible or communicable disease. The bacillus Bordetella pertussis is an airborne bacterium‚ however it can rarely be transmitted through fomites. D. What are the signs and symptoms of this disease? How long does it take for this infection to be completely resolved

causes frequently fatal glaucomatous disease with lung lesions and abscesses throughout the body. It can also cause Meningitis and is 90% fatal if left untreated. Common infections can occur in arid and semiarid areas of the western hemisphere. Dusty fomites from endemic areas can transmit infection elsewhere. It affects all ages‚ both sexes‚ and all races; and is common in summer after wind and dust storms. Coccidioides immitis mode of transmission is mainly due to inhalation of infective arhroconidia

about 7000 hospitalized‚ Oklahoma had about 946 hospitalized and 26 dead‚ lastly 78 kids have died from influenza each year. The speakers stressed on the fact that we should wash hands regularly to prevent influenza. The speakers told to be wary of fomites. Viruses reproduced in fertilized chicken eggs make the influenza vaccines. Influenza causes acute febrile respiratory infection. Children may have abdominal pain and vomiting. Children‚ elderly‚ and immune-compromised individuals are at risk. The

similar to that of the “wild” infection. In the end‚ the body will know how to attack the virus when it should come in contact with the “wild” form. The movie also describes how a respiratory virus can spread easily by coughing and even touching (fomites). In the movie‚ I was reminded of how often we touch our faces during the day and how much we touch each other. Contagion also had a pretty realistic

spreading the dread rather as simply. And to think that not only do we need to be careful of transmitting the virus to others but also to prevent it from getting into us. It had been explained that the virus could also transmit through what is called a fomite that is “any animate object or substance capable of carrying infectious organisms.” Even though this meant that a virus could also spread through transmissions with surfaces touched by someone infected beforehand‚ it could still be prevented as the

The Causes of Infection An understanding of commonly encountered mi cro-organisms is essential for good infection control practice. Micro-organism s that cause disease are referred to as pathogenic organisms.
Premium Infectious disease Infection
Equine influenza is a common respiratory infection of horses caused by an orthomyxovirus of the genus Influenza A. Influenza A viruses can be divided into sub-types on the basis of the antigenic reactivity of the surface glycoproteins‚ the haemagglutinin (H1-H16) and the neuraminidase (N1-N9) molecules (Fouchier et al.‚ 2005). Equine influenza (EI) is caused by two subtypes H7N7 and H3N8. Outbreaks due to H7N7 are limited as the isolation of the virus has not been reported since last two decades
