In the past, doctors have largely believed that bacteria has been the cause of most pneumonia cases. While the flu has often been linked to the disease, bacteria within the environment was long considered the root of pneumonia. Although, new research shows that viruses are actually the cause of most cases.
Pneumonia often resembles bronchitis with its symptoms, causing a lung infection, cough, fever, nasal congestion, and shortness of breath. But, without treatment, these symptoms can become life-threatening. People of all ages are susceptible to the infection, but it can be treated with medication and prevented with a vaccine.
Every year, pneumonia kills almost 1 million children. This new research could be vital in understanding what causes pneumonia and how to prevent these deaths from occurring.
