Something You Need to Know About Pneumonia

Pneumonia is an infection of the lungs that caused by bacteria, viruses, and fungi. Though the infection can cause illness in people of all ages, it is the leading infectious cause of death in children younger than 5 years old worldwide.

Pneumonia and its symptoms can vary from mild to severe, which is commonly a complication of a respiratory infection—especially the flu—often causes cough, fever, chills and shortness of breath. Depending on the cause, doctors often treat pneumonia with medicine. Due to the nonspecific symptoms, the differential diagnoses of different type of cases become the most important task for clinicians.

Mycoplasma pneumonia (M.pneumonia) and Chlamydia pneumonia (C. pneumonia) are one of the important causes of Pneumonia.1 M.pneumonia is a human pathogen that causes the disease mycoplasma pneumonia, which can cause acute respiratory illness and the illness usually has a gradual onset over a period of 1 to 4 weeks. C. pneumonia is also a common cause of pneumonia around the world. It will cause illness by damaging the lining of the respiratory tract including the throat, windpipe and lungs.2 Peoples may become infected and have mild or no symptoms.

People spread C. pneumonia and M.pneumonia by coughing or sneezing, which creates small respiratory droplets that contain the pathogen.3 It can also spreads through sick person’s tissue droplet. The infections usually have long incubation periods (the time between breathing in the bacteria and developing symptoms). Symptoms usually begin 3 to 4 weeks after exposure.4 Therefore, it is necessary to perform an early serological test for these pathogens.

This World Pneumonia Day, YHLO encourages people to raise awareness of pneumonia diseases. We aim to provide an easy and intelligent diagnostic method to reduce the damage from C. pneumonia and M. pneumonia, and provide a better life to the patient.
