Pneumonia is not just a single infection or disease provoked by a specified bacteria or virus but it can be triggered by a number of various causes like trauma, physical injury, chemical burns, poison exposure, etc. When pneumonia affects an individual, he or she suffers from lung inflammation, in particular alveoli. In fact, alveoli are small hollow cavities in lungs that help gases exchange (impure and pure). Sometimes lungs are filled with exudation and consolidation fluids. Primary pneumonia symptoms include cough, fever, cold, fever and flu symptoms. Apart from pain in chest there is difficulty breathing involved. Frequently pneumonia is confused with flu.

Pneumonia is caused by different microbes, including bacteria, viruses, fungi, parasites, and several Idiopathic causes. The contagious rate is extremely high as the infection may travel fast. The best and simplest way to control the contagious character of pneumonia is community cleanliness and basic hygiene.

The invasion of microbes in the body triggers the infection. Usually the microbes are held off by natural body defenses. However, unavoidable and direct consumption of infected air and contact of infected objects triggers contagious disease. The microbes settle in the respiratory system beginning from the nose to alveoli and lungs. White blood cells activate the defensive system of the body, resorting to fluids secretion, lung inflammation and pus ejection trying to combat the infection. This situation arises seldom, due to the fact that microbes are warded by the respiratory system, but being invaded, the respiratory tract weakens and health problems can worsen significantly.

Is Pneumonia Contagious?

Pneumonia is extremely contagious and such simple things as, not using a handkerchief while coughing or sneezing can contribute to pneumonia spread. The problem is that microbes can invade and attack anything. Common cold, smoking, as well as general diseases can work in connection with pneumonia provoking viruses.
Pneumonia can follow minor ailments, given the fact that the immunity is weakened the body cannot suppress viruses causing pneumonia. Pneumonia and its causes can be classified in several ways. As a matter of fact, community-acquired pneumonia is the most frequent and contagious type of disease. Usually community-acquired pneumonia spreads because of the microbes present in the environment, and individuals infected often tend to have pneumonia. Adults have stronger immunity than old people and kids. This helps them to combat many dangerous bacteria and viruses. However this cannot guarantee the prevention of pneumonia spread! Always remember that pneumonia is extremely contagious and be careful!
