Symptoms of pneumonia

Second Mayo Clinic of the United States, the pneumonia “It’s an infection that inflames the air sacs of one or both lungs. The air sacs may fill with fluid or purulent material, causing coughing with phlegm or pus, fever, chills, and difficulty breathing.

THE Acquired pneumonia is the most common and it happens outside hospitals. Certain bacteria (Streptococcus pneumoniae) are responsible for lobar pneumonia, which can develop spontaneously or after a cold or flu.

A milder case ambulatory pneumonia, is produced by an organism similar to a bacterium (Mycoplasma pneumoniae) and does not require rest or hospitalization. On the other hand, people with chronic health problems or weakened immune systems can be affected by different types of fungi.

As for the virusthey also cause some of those that cause colds or flu pneumonia. Common in children under five, viral pneumonia is usually mild, but can be very serious. This is the case of the coronavirus that causes Covid-19, which has caused severe pneumonia.

This disease can be more or less serious. In infants and young children it is more serious. Second World Health Organization and the leading cause of infant death in the world. This also implies a greater risk for people over the age of 65 and those who have other health problems or a weakened immune system.

Between symptoms of pneumoniaTHE Mayo Clinic highlights: chest pain when breathing or coughing; difficulty breathing; cough with phlegm; fever, sweating and chills; nausea, vomiting or diarrhea. Furthermore, it is reported that adults over the age of 65 may suffer from disorientation and that young children, in some cases, usually have no symptoms.

2. Red hepatitis. During which red blood cells enter the fluid to fight the infection. Gray hepatitis. The red blood cells begin to degrade and the immune cells remain.
3. Gray hepatitis. The red blood cells begin to degrade and the immune cells remain.
4. Resolution. It occurs when these cells begin to clear the infection and coughing expels the fluid left in the lungs.
