Bacterial Pneumonia - Very Serious Condition

A respiratory disease, pneumonia can be a very dangerous infection caused by bacteria, fungi, parasites, viruses, or an injury to the lungs. The adverse agents enter the body through breathing, or through the eyes. Pneumonia can affect one or both sides of the lungs if the person’s body is not capable to defending itself from the elements that can lead to an infection. The symptoms of pneumonia are vast, ranging from chest, muscle and abdominal pain, to high body temperature and severe coughs, to diarrhea, vomiting and overwhelmingly feeling exhausted. As far as the treatment goes, it strictly depends on the underlying agent that caused pneumonia in the first place. If the infection is bacterial or mycoplasmal, there are antibiotics that will cure it. However, if pneumonia resulted from a viral infection there are no medical treatments. Over time, the body will fight the virus and the infection will go away. It is very important to note that the infected individual’s conduct during the disease greatly affects the outcome of the treatment as bacterial pneumonia can keep coming back unless it was successfully fought off the first time. For instance, it is absolutely imperative that the person lies in bed for a few weeks, eating a light, doctor recommended diet. Only if the person follows these rules will the antibiotics, in the case of a bacterial infection, do their job, and it is crucial to beat the infection the first time it develops for if it comes back it does so on a much greater scale. Recovering from pneumonia usually takes a few weeks, up to a month, while some of the more prominent symptoms, like a cough, can follow the person for even longer.

Pathophysiology of Pneumonia

Pneumonia will develop when the alveoli of the lungs get inflamed and start filling up with excess liquid, while they are supposed to be filled with air. Further, pneumonia can result from various types of lower respiratory infections that the body was unable to fight off and in turn they escalated. A bacterial kind of pneumonia is the most prevalent, with streptococcus pneumoniae being the leading bacteria to cause this type of infection. In addition, the development of pneumonia occurs in 4 distinctive stages. After the initial infection, the first symptoms will occur within one day, in a form of a high body temperature and cough. During the first stage, the clogging of the alveoli takes place while the lungs are being attacked by bacteria. During the second stage the lungs are overwhelmed by the existence of epithelial cells, neutrophils and erythrocytes. The sign that the pneumonia is in its third stage is the brownish colour of the lungs produced by a combination of hemosiderin, decomposition of red blood cells, and fibrinopurulent exudates. The fourth or the final stage is the stage in which the negative elements are defeated by the person’s immune system and the optimal functioning processes are returned to normal.

Are Young Children More Vulnerable to Pneumonia?

As previously mentioned, pneumonia is the most prevalent cause of death among young children and it is usually produced by a viral or a bacterial infection. The symptoms in young children resemble those of a cold and while pneumonia is not contagious per se, it can be passed on to others through bodily liquids. As far as the causes of children’s pneumonia go, as is the case with adults, strains of the streptococcus bacteria are most often responsible for the development of the infection. The symptoms are again very similar, including chest pain, diarrhea and exhaustion. When it comes to viruses, those which cause children’s pneumonia are usually strains of the influenza virus, respiratory syncytial virus, rhinovirus, and adenovirus. The symptoms of a viral pneumonia are similar to those of the bacterial except for the severity of the cough, which is stronger when produced by a virus. Finally, those children who have respiratory problems, are exposed to smoke, and do not have a proper intake of healthy nutrients on a daily basis are more likely to develop pneumonia.

Treatment and Prevention of Pneumonia in Young Children

Pneumonia is routinely diagnosed using x-rays, blood tests and visual examinations, while the course of treatment will depend on the underlying cause of the infection. As is the case with adults, if the children’s pneumonia is caused by bacteria, antibiotics will be prescribed, while the viral infection will heal over time. Similarly, children must lie in bed and eat a proper diet for the duration of the treatment. When it comes to preventing pneumonia in children, a shot called pneumococcal conjugate vaccine is widely administered. However, as preventing any kind of illness goes, good, balanced diet and lots of physical activity coupled by a good overall hygiene of the child go a long way.
