Since early May 2022, numerous cases of Monkeypox (Mpox) have been reported globally in non-endemic areas. However, despite numerous reports worldwide, the epidemiological and genomic information related to the 2022 multi-country outbreak remains scarce in South America. By late June 2022, the first Mpox cases were detected in Colombia. Cartagena is a Colombian Caribbean city with high domestic and international connectivity, and, therefore, is vulnerable to the introduction of the Monkeypox virus (MPXV). This report provides an in-depth description of the epidemiological, clinical, and virological characteristics of the first four cases detected in Cartagena including three cases with no history of recent travel and one imported case. Using various laboratory tools based on PCR, next-generation sequencing, and viral isolation and quantification methods, the MPXV clade IIB was detected and isolated. Importantly, infectious viral particles were identified in lesion swabs collected from all cases and in oropharyngeal swabs collected from two cases. Blood samples tested negative using PCR and isolation. In summary, our work contributes complete genomic, clinical, and epidemiological information that will be useful for a number of studies going forward, and it also documents local information that contributes to our understanding of Mpox at the local level.
