Seasonal Variations in Rhino-Cerebral Mucor Infection

Abstract

Objectives:

Rhino-orbito-cerebral mucormycosis (ROCM) is an uncommon, potentially lethal infection that occurs mostly in immunocompromised hosts. The seasonal occurrence of ROCM was studied in two of Israel's largest medical centers.

Methods:

A total of 36 patients were seen during a 25-year period in this retrospective bi-institutional cohort study. Meteorologic data were obtained and analyzed for a possible linkage of infection with precipitation and temperature.

Results:

Twenty-one of the 36 patients (58%) presented between the months of August and October, and 27 patients (75%) presented between the months of August and December. A peak incidence of ROCM was noted in the month of September (13/36 patients; 36%). No association was noted between meteorologic conditions and the incidence of ROCM infection.

Conclusions:

A consistent seasonal peak was observed in ROCM. Heightened awareness is important for early recognition and treatment of this disease.
