To conquer this limitation, we examined the spatial distribution of epidemic EM, and explored the association between temperature fluctuation and epidemic EM outbreaks in China.

A two-stage model was utilized to characterize the partnership between heat range fluctuation and epidemic EM outbreaks. The majority of EM cases were middle school students, with a higher incidence rate in resident and female students.The COSM program includes guest lectures by prominent leaders in surgery; numerous programs and scientific periods and a large number of papers reflecting research linked to current problems in the diagnosis, evaluation, and treatment of otolaryngology-related conditions.
