Introduction: Cryptococcosis is the second most frequent cause of opportunistic infections in human immunodeficiency virus (HIV) patients in Colombia. We aimed to determine the prevalence of cryptococcosis in the Colombian department of Atlántico. Methods: An active search for cryptococcosis cases was conducted between 2015 and 2017 in health institutions by distributing surveys to clinicians and characterizing samples phenotypically and genotypically. Results: Thirty-eight cryptococcosis cases were identified (81.6% men, 76.3% HIV patients). The calculated annual prevalence was 5.08/1 million inhabitants. Cryptococcus neoformans var. grubii VNI was isolated in 34 cases. Conclusions: These results provide the basis for passive surveillance of cryptococcosis.

Cryptococcosis is a life-threatening mycosis reported mainly in human adults with low frequency in children. High mortality rates may occur in cases with late diagnosis therefore, a timely suspicion of this pathology is important. Cryptococcus gattii is the less prevalent species complex predominantly isolated from apparently normal hosts. We report a fatal case of neurocryptococcosis in a Colombian minor without known risk factors, in Barranquilla, Colombia. The patient was hospitalized for neurological assessment with a recent history of intense headache, vomiting, anorexia, loss of consciousness, drowsiness, inability to recognize family members, disorientation, aphasia and anxiety. Despite initiating antifungal treatment after isolation of the fungus from cerebrospinal fluid (CSF), the patient died early due to his deteriorated condition.
