There are other human pathogens which were documented as members also of the Legionella species. This was discovered based on the isolation from clinical material (The Epidemiology of Infectious Diseases, 2003). The two major clinical manifestations of infection from the Legionella bacteria are the Pontiac fever and the Legionnaires’ disease. This disease may be sporadic or epidemic. Also, it may also be nosocomial or community acquired.
SZT Task # 3 Measles The measles, also known as rubeola, is a viral disease that affects the respiratory system. Measles is caused by the paramyxovirus family. The virus grows in the cells that line the back of the throat. (WHO) The measles disease is highly contagious and is transmitted by respiration either by indirect contact such as aerosol exposure or direct contact such as exposure to fluid in an infected person’s mouth and nose. (Wikipedia contributors) The virus also remains alive and contagious on exposed surfaces and in the air for up two hours.
Raven Johnson Mr. Montgomery 3/14/12 Bubonic Plague The Bubonic Plague is a deadly infectious disease, which is caused by the bacterium Yesinia pestis. It is transmitted through the bite of a flea, and has killed millions of people. This plague is one of the most feared of all diseases (McNeill, W. H.). It is easily transmittable and has a high mortality. It can be cured through antibiotics (McNeill, W. H.).
The flu begins abruptly, causing high fevers, generally 102 -106F, headache, tiredness, dry cough, sore throat, muscle aches and stiffness, chills, fatigue, malaise, sweating, nausea, vomiting, dizziness, lack of appetite, and worsening of other illnesses such as heart failure or asthma. The fever will typically last up to five days. General body symptoms such as body aches, nausea, vomiting, and sweating should decrease at about the third day and respiratory symptoms should then begin to set in. The flu virus can emerge anywhere in the respiratory system, producing the indications of a cold, croup, sore throat, bronchitis, ear infections, or pneumonia, these symptoms should start to diminish at around four to seven days. The tiredness and coughing can lasts for weeks after the flu is
After the research was no more need of use, McCoy evacuated the Hygienic Laboratory and began to kill the experiment animals. This would contain and prevent another disastrous outbreak. A few months later when everything is contained congress grants the Hygienic Laboratory with a new name, The National Institute of Health. This epidemic brought disease and catastrophe. Parrot Fever spread throughout America, and eventually brought death to one of five people that were infected.” There were a total of a hundred and sixty-nine cases of psittacosis nationwide.
In 1999 the virus appeared in North America for the first time and in the next year spread to 12 states killing 8 people and sickening 80 others. (Lee, M.C. 23-34) C. In the U.S., birds appear to be the major carrier of the disease and they pass it on to humans as follows: 1. When mosquitoes feed on the blood of the infected birds, the insects ingest this virus. 2.
Preston also produces an effective atmosphere of fear by displaying that doctors, who are almost always viewed as being heroic, can just as easily, if not so faster than any human being, get the virus. Preston constantly reminds us of how tiny and how dangerous a virus is. The impact of Ebola or Marburg could extinguish the entire planet if it got a grip. “Within 24 hours, a virus could make its way out of Africa on a plane and into such places like London, Paris, or New York and then spread out to the rest of the world.” The tiny HIV virus has already spread damage throughout the human population of the world, and this is a point the author makes numerous times. A very minute amount of contaminated blood is enough to infect a human with the Ebola virus, so those working in the Hot Zone must always be careful for the smallest little tear that might allow it into their space suits.
It is the most common, and can range from mild to severe; however it is not the only form of lupus (Blau 45). Cutaneous lupus erythematosus, or CLE, is another form of lupus (CDC). People who have CLE only have skin problems, but their butterfly rash is often more severe than people who have systematic lupus (CDC). Also, when patients have CLE, it is recommended that they stay out of direct sunlight as much as possible to keep their rashes from acting up (CDC). Another type of lupus is drug-induced lupus erythematosus, or DILE (Lupus Foundation of America).
As the components of the body’s immune system, the cells have white blood cells, and are responsible for defending the body against any infection or virus. HIV doesn’t just destroy the most important component of the body’s defense, but the body struggles with the virus to sustain within the body, and within the host system. “ The disruptive effects however; cause the immune system to fail in differentiating foreign bodies that it even attacks its own components leading to the development of AIDS” (AIDS.gov,2009). Various ways HIV can be transmitted When someone gets HIV the person is at high rate to get AIDS later on in their life. HIV is the first stage, and AIDS is the last stage of this horrible disease.
Polio is a crippling and potentially deadly infectious disease caused by a virus that spreads from person to person invading the brain and spinal cord and causing paralysis. Because polio has no cure, vaccination is the best way to protect yourself and the only way to stop the disease from spreading. The spread of polio has never stopped in Afghanistan, Nigeria and Pakistan. Polio-virus has been reintroduced and continues to spread in Chad and Horn of Africa after the spread of the virus was previously stopped. In the late 1940s to the early 1950s, in the United States alone, polio crippled around 35,000 people each year making it one of the most feared diseases of the twentieth century.
