Pneumonia or medical term pneumonia is an infection of one or two of the lungs that is usually caused by bacteria, viruses or fungi. Currently, more than 3 million people are infected with pneumonia. More than half a million people treated in hospital for hospitalization. its 5% will die from pneumonia, and the disease is still the leader of the six causes of death in America.
How do people "get pneumonia? '
Some cases of pneumonia acquired by inhaling mists small (droplets) containing organisms that can cause pneumonia. Drizzle it into the air when a person infected with these germs coughs or sneezes. In other cases, pneumonia is caused when bacteria or viruses that are normally present in the mouth, throat, or nose inadvertently enter the lung. During sleep, it is entirely common for people to suck secretions (expenses) from the mouth, throat, or nose. Normally, the body's reflex response (coughing out secretions) and immune system will prevent organisms sucked cause pneumonia. However, if someone is in a weakened condition from another illness, a severe pneumonia can develop. People with viral infections recently, lung disease, heart disease, and swallowing problems, as well as users of drugs and alcohol, and those who have suffered a stroke or epilepsy are at high risk of developing pneumonia than the general population.
Once organisms enter the lungs, they usually settle in the air sacs of the lung where they rapidly grow in number. Area of the lung then becomes filled with fluid and pus as the body attempts to fight off infections.
Symptoms And Signs of Pneumonia
Most people who are infected with pneumonia initially have symptoms of a infuensa which is then followed by a high fever (sometimes as high as 104 degrees Fahrenheit), chills, and a cough with production of sputum (phlegm). Sputum is usually discolored and sometimes bloody. People with pneumonia may become short breath. The only pain fibers in the lung is the lung surface, in the area known as the pleura. Chest pain may develop if the pleural aspects of the outside of the lung involved. This pain is usually sharp and worsens when taking a deep breath, known as pleuritic pain.
In other cases of pneumonia, may occur a slow onset of symptoms. A worsening cough, headaches, and muscle aches may be the only one of the symptoms. In some people with pneumonia, coughing is not a major symptom because the infection is located in areas of the lung away from the airways is greater. At times, an individual's skin color may change and become dusky or purplish (a condition known as "cyanosis") due to their blood dioksigenasi poorly.
Children and babies who contracted pneumonia often do not have any specific signs anywhere from a chest infection, but hit a fever, appear quite ill, and may become lethargic. Those older people may also have few symptoms with pneumonia.
