3. Pneumonia
Airborne bacteria, fungi, and viruses are the possible causes of pneumonia. This lung infection can be diagnosed as severe or mild, depending on the severity of symptoms. The disease has a more profound effect on older adults and infants. If not treated immediately, it can become a life-threatening condition.
Pneumonia risk factors include weakened immune systems that are trying to recover from other infections, such as the flu. You also run the risk of contracting pneumonia if you have a pre-existing health problem, or you drink alcohol or smoke cigarettes.
Symptoms of pneumonia include fever, fatigue, cough, shortness of breath, chest pain, as well as diarrhea, nausea, and vomiting. A chest X-ray diagnoses pneumonia and the cause of the disease discovered using a blood test or analysis of phlegm.
Lobar pneumonia is confined to one part of the lung, while bronchopneumonia infects several areas at once. If left undiagnosed and untreated, pneumonia can develop dangerous complications such as bacteria in the blood, accumulation of fluid in the lungs, or the development of abscesses.
