Signs of Pneumonia

Pneumonia is an inflammation of the lung parenchyma. There is variability in how the criteria for diagnosis as there are authors who require only the presence of radiographic infiltrates on chest radiograph while others just the presence of respiratory symptoms.

In general, pneumonia is defined as the presence of fever and / or respiratory symptoms and evidence of parenchymal infiltrates on chest radiograph.
In 1994, WHO published a guide for diagnosis of pneumonia with five clinical parameters: respiratory rate, chest retractions, cyanosis, feeding difficulty and absence of wheezing.
 This guide is intended for high-burden countries by NAC, low socioeconomic status, poor access to hospitals and medicines. Today, in developed countries is accepted the appropriateness and usefulness of radiological confirmation for diagnosis.
Pneumonias are classified into two groups:


Community-acquired (or extra-hospital). The most typical are the pneumococcal pneumonia and Mycoplasma pneumoniae.
Hospital Pneumonia. They tend to be far more serious, as the host defense mechanisms are often affected and the causative organisms are usually much more resistant.
The typical signs and symptoms of pneumonia are:
  • Fever, chills and sweating.
  • Productive cough with mucous expectoration, yellow, salmon-colored, purulent (according to the causative organism).
  • Chest pain that increases with breathing and coughing.
  • Headache.
  • Muscle and joint pain.
  • Lack of appetite, weakness and malaise.
  • Dyspnea (difficulty breathing), in some cases.
  • Crackles on auscultation in the affected area.
It is vital to know and understand the signs of pneumonia in order to accurately identify it with the appearance of the first symptom. Pneumonia is a breathing condition which is caused by an infection of one or both of the lungs in a human body. Pneumonia is primarily caused by bacteria and viruses that may be living in your nose. Some of these bacteria can be breathed directly into the lungs from hair making it quite difficult to prevent pneumonia. Pneumonia caused by bacteria is extremely dangerous hence the need to discuss the various signs of pneumonia.
The sign of pneumonia may vary depending on the type of pneumonia under question. There are generally two types of this disease namely community acquired pneumonia and Hospital pneumonia. The later tends to be more dangerous and severe and calls for extra care and prompt treatment when its symptoms are correctly diagnosed. However, besides the signs and symptoms of these two types of pneumonia tending to show some variations, it is necessary to note that there are typical symptoms that are common to them. Once the common symptoms are observed, it is essential for medical personnel to perform further examination to accurately determine the exact type of pneumonia in order to prescribe to appropriate medication.
Cold, fever and high temperatures at times rising to 104 F are the initial common signs of pneumonia. A cough which produces sputum is also likely to be observed. Usually, the sputum is colored and at times can be bloody depending on how serious the cough is and the period in which the pneumonia virus has taken to show up the first sign. Chest pain is expected to develop although it can be a direct result of intense and persistent coughing. Due to the fact that the pneumonia virus attacks the lungs, the pleura fibers on the surfaces of the lung are directly affected, therefore cause pain and discomfort along the lung cavity regions. Medical experts actually refer to this symptom as pleurisy. If pneumonia is not treated by this point, this is likely to sharpen and a lot of pain felt by the victim while taking a deep breath.
Pneumonia in its enhanced stages can cause loss of appetite, malaise and subsequently weakness. These symptoms can be described as opportunistic as they develop when the body does not respond sufficiently enough to counter the effects being caused by Pneumonia. This lack of sufficiency by the body gives an opportunity for other symptoms to attack it. In instances of bacterial pneumonia, the affected area experiences crackles on auscultation.
There are indeed quite a number of signs of pneumonia. However, it is crucial to note that different people react differently to different diseases, pneumonia included. One person may exhibit all the signs of pneumonia while another may not even show a single symptom, but he or she is actually infected by the virus that causes pneumonia. Of even greater importance is to protect yourself against predisposing factors of pneumonia. Always stay warm and see your doctor for regular checkups and virus scans.
