Today I'm talking abou tá disease that is not so feared today, but it was one of the deadliest of the past: Pneumonia

Pneumonia is a lung infection that causes inflammation in the alveoli, where gas exchange occurs. It can be caused by different agents such as bacteria, viruses, fungi, or by inhaling harmful substances. The disease primarily affects people with weakened immune systems, such as the elderly, children, and those with chronic illnesses. Its main symptoms include fever, productive cough, chest pain, and difficulty breathing.
