After their corona break of several years, the pneumonia pathogens mycoplasma have led to record levels worldwide on their return. This was shown by an international research team under Swiss leadership in a new study in the journal "The Lancet Microbe".

"The number of mycoplasma cases was truly historic," said study leader Patrick Meyer Sauteur from the University Children's Hospital Zurich to the news agency Keystone-SDA. In Switzerland, too, the pathogen had led to record levels until last December. "Almost the whole of Switzerland was coughing because of mycoplasma." The numbers have since plummeted again.

Before the pandemic, mycoplasma was one of the most common bacterial pathogens causing pneumonia in children. The coronavirus measures led to a slump in transmissions. They only returned in the second half of 2023. Contrary to fears, however, there was no significant percentage increase in severe cases despite a lack of immunity, as the researchers showed.
