Climate variability and nonstationary dynamics of Mycoplasma pneumoniae pneumonia in Japan.

<h4>Background</h4>A stationary association between climate factors and epidemics of Mycoplasma pneumoniae (M. pneumoniae) pneumonia has been widely assumed. However, it is unclear whether elements of the local climate that are relevant to M. pneumoniae pneumonia transmission have statio...
