Guide To The Most Common Respiratory Illnesses

Pneumonia

Pneumonia occurs when an infection causes inflammation in the air sacs in the lungs. It may affect both lungs or only one. The affected air sacs might fill up with pus or fluid, leading to a productive cough, difficulty breathing, chills, and a fever. Several organisms can cause pneumonia, including fungi, viruses, and bacteria. Some cases of pneumonia are mild, though others can be life-threatening. Pneumonia is more likely to be serious in seniors and individuals with certain underlying conditions. This includes a weakened immune system, respiratory issues, or mobility issues. 

Pneumonia patients may experience chest pain with breathing and coughing, fatigue, a fever, and a cough that produces phlegm. Some individuals may also experience vomiting, diarrhea, and nausea. In adults over sixty-four years old, pneumonia may cause changes in mental awareness and confusion. It may cause a lower than average body temperature in seniors and those with weak immune systems.
