Rising Respiratory Illnesses: Examining the Role of Mycoplasma pneumoniae and Strategies for Prevention

Mycoplasma pneumoniae is indeed an atypical bacterium that's been increasingly associated with respiratory illnesses, particularly in China in recent months. It's concerning how this bacterium has contributed to the rise in influenza-like illnesses, especially in northern provinces. While it's a recognized pathogen causing symptoms similar to those of a common cold, the significant increase in reported cases warrants careful observation and consideration of its role in the current spike of respiratory illnesses in China.


This bacterium causes a range of symptoms, such as a dry cough, fever, and mild shortness of breath, resembling what's often termed "walking pneumonia." The ease of transmission in crowded spaces like schools and nursing homes poses a significant risk. Consequently, healthcare professionals might need to consider comprehensive testing for Mycoplasma pneumoniae alongside other known respiratory pathogens, especially among school-age children who seem to be more affected.


While Mycoplasma pneumoniae is a prevalent cause of community-acquired pneumonia from atypical bacteria, it's vital to emphasize that only a fraction of infected individuals develop pneumonia. Nevertheless, given the recent surge in respiratory illnesses, a thorough testing approach can aid in accurate diagnoses and prompt treatment, ensuring appropriate care for those affected by Mycoplasma pneumonia. Observing closely until the spring may provide further insights into the impact and spread of this bacterium in the affected regions.


Symptoms and Risk Factors


The symptoms of Mycoplasma pneumoniae (MP) typically include low-grade fever, dry cough, mild shortness of breath (especially with exertion), and fatigue.


At-Risk Individuals

Certain individuals, such as older adults, those with compromised immune systems, lung disease, sickle cell disease, or children under 5, are at higher risk.



In rare cases, MP can lead to complications affecting the heart, central nervous system, joints, pericardium, and other organs. It can also cause rare and dangerous skin conditions, kidney failure, and rare ear problems.


Diagnostic Methods


Diagnostic options


Molecular tests

Molecular Diagnosing and testing for Mycoplasma pneumonia typically involve the Mycoplasma pneumonia PCR Test. This non-invasive diagnostic test uses PCR technology to detect bacteria in the lungs. It helps identify the specific bacteria causing the infection, enabling doctors to select the most suitable treatment. The test requires a simple sputum or oropharyngeal swab sample for analysis and is often combined with other diagnostic methods for a comprehensive diagnosis of Mycoplasma pneumonia.


Availability of molecular test kits

Daan Gene currently provides a commercial PCR detection kit for molecular testing in clinical and public health laboratories worldwide. The Diagnostic Kit for Mycoplasma pneumoniae DNA has obtained CE-IVD and NMPA approval, making it a reliable tool for in vitro qualitative detection of Mycoplasma pneumoniae (MP) DNA in human sputum or oropharyngeal swab specimens. This kit has a sensitivity of 6.65×10^2 copies/mL, ensuring accurate and efficient detection of the bacteria.
