What is pneumonia? Pneumonia is an infection of the lower respiratory tract, invasion of lung tissue >> << that may cause symptoms that range from mild to life threatening. According to the Centers for Disease Control and Prevention (CDC), more than 1 million children and adults in the U.S., hospitalized pneumonia each year. Worldwide, pneumonia kills more people than any other infectious disease, more than 4 million people strattera price a year, half of them under 5 years. Although anyone can get pneumonia, it is the most common and potentially serious in those who are very young, over 65 years, or who have underlying disease or condition that affects their lungs. This includes people who have had or
organ transplants and those on chemotherapy, pregnancy, in the intensive care unit (ICU) on mechanical ventilation, have been injured or damaged lungs, such as smoking or which is
, like. Pneumonia can occur at any time, but the largest number of cases observed during seasonal season
, usually late fall to early spring. Lung infection may occur in five different ways:
Microorganisms can move down from the upper to the lower respiratory tract. Airborne droplets from sneezing or coughing can breathe. or other discharge from respiratory can touch hands and spread to the mucosa. the lungs. The infection can spread from localized site in the body through the blood and the lungs. It takes more than the impact of potential pathogens () to get pneumonia. Microorganisms permanent presence in the environment and people face the source of infection on a daily basis. In most cases, can easily take care of microbial attack. In the body are layers of protection, which include mechanical barriers, protective bacteria (
), and immune system. Pneumonia occurs when these defense mechanisms are weakened or damaged, and / or invasion by virulent microorganisms enough to overcome or circumvent them. Wide range, and (rarely)
or can lead to pneumonia, but in most cases are caused by only a few of them. Most likely, the microorganism that causes a special case of pneumonia depends on the age and health of the victim and to some extent on the season. Those with weak immune systems and those who traveled in specific regions of the world may develop pneumonia, due to the more unusual microorganisms. Pneumonia can be grouped by medical community in various categories. These differences are primarily useful for determining the probable cause of pneumonia, to determine how best to prevent the spread of infection, and in the treatment. Hospital of pneumonia, infection occurs when, for example, after surgery, when connected to a machine or mechanical ventilation in intensive care
Healthcare-associated pneumonia when a person is infected, and health-related development, such as nursing home or dialysis clinic
nosocomial and health related microorganisms likely to be resistant to first-line drugs. Acquired pneumonia, probably due to the bacteria, which often tend to prescribe antibiotics or due to seasonal viruses for which antimicrobial agents are not appropriate treatment. .
