Increase in mucormycosis hospitalizations in southeastern Brazil during the COVID-19 pandemic: a 2010-2021 time series.

Background: Mucormycosis is a severe invasive fungal disease. During the coronavirus disease 2019 (COVID-19) pandemic, outbreaks have been reported worldwide, but epidemiological studies are still scarce in Brazil.

Methods: We conducted a time-series cohort hospitalization study (2010-2021) in southeastern Brazil.

Results: There were 311 cases (85 during the pandemic), with significant (P < 0.05) involvement of patients older than 40 years (84%), white patients (78%), rhinocerebral site (63%), and São Paulo State residents (84%).

Conclusions: Mucormycosis hospitalizations were highly prevalent. Further studies are needed to assess the burden of COVID-19 on mucormycosis in Brazil.
