Pneumonia Disease Project
Transcript of Pneumonia Disease Project
Disease Project Pneumonia Pneumonia has many possible causes, but the most common ones are bacteria and viruses normally encountered in the environment. Usually your body keeps these microbes from invading your lungs. Sometimes, though, a robust germ can breach your defenses, regardless of your general health. The germs that cause pneumonia in otherwise healthy people are not usually the same ones that cause pneumonia in hospitals and other health care settings. Similarly, the germs that can infect your lungs if you inhale foreign substances (inhalation or aspiration pneumonia) differ from those that cause more-common types of pneumonia. The same is true of the germs that cause pneumonia in people with weak immune responses. Causes of pneumonia The germs that cause pneumonia are usually found in the mouth and nose of the infected person. They can be spread easily to another person, either through the air or by touching a contaminated surface. Typically, they enter the person's body through their mouth, nose, or eyes. When this happens, a battle begins -- the person's immune system tries to kill the germs, while the germs try to multiply. Although a person with either viral or bacterial pneumonia is contagious, that person's germs are more likely to cause an upper respiratory infection in another person (such as the common cold) than pneumonia. This is because many of the viruses and bacteria that cause people to get pneumonia are the same ones that cause upper respiratory infections. How is pneumonia spread? The signs and symptoms of pneumonia may include:
Lower-than-normal body temperature in older people
Shortness of breath
Chest pain that fluctuates with breathing (pleurisy)
Fatigue Symptoms Pneumonia is an illness of the lungs and respiratory system in which microscopic air-filled sacs in the lungs become inflamed and flooded with fluid. Pneumonia affects about one in 100 people in the UK each year and while it can affect any age group, it is most common in those over the age of 70.A quick diagnosis is vital to improving a patient's chances of survival, including tests such as x-rays and an examination of fluids in a laboratory in order to identify the micro-organisms causing the illness and the correct antibiotics needed. Without treatment, the mortality rate from bacterial pneumonia can be as high as 40 percent. Effects of Pneumonia Get vaccinated. Although a long list of germs and inhaled irritants can cause pneumonia, vaccination lowers your risk of two leading offenders. Vaccinations include seasonal flu shots, pneumonia vaccines, and childhood vaccines. Also, take care of yourself. Wash your hands, don't smoke, stay rested and fit, and eat a healthy diet.

Bibliography Treatment/Cure The approach to treating patients with pneumonia generally involves:
Deciding who can be treated at home and who needs to be in the hospital
Deciding whether a patient needs antibiotics, and which antibiotics are appropriate
Providing appropriate supportive care
Deciding what follow-up and preventive care are needed
Whether patients are treated at home or admitted to the hospital, receiving their first dose of antibiotics quickly improves the outcome of the illness and the speed at which they get better. Scientific Discoveries Pneumonia is a leading cause of death and hospitalization, costing health care systems billions of dollars and an estimated 600,000 adult deaths worldwide each year. Pneumococcal disease is caused by the bacterium Streptococcus pneumoniae and the term describes a group of illnesses, including invasive infections, such as bacteremia/sepsis and meningitis, as well as pneumonia and upper respiratory tract infections. Although all age groups may be affected, the highest rate of pneumococcal disease occurs in young children and older adults. In addition, persons suffering from a wide range of chronic conditions (eg, diabetes, cardiovascular disease) and immune deficiencies are at increased risk.
