![]() ![]() ![]() MATERIALS AND METHODS Diagnosis, DNA Sequencing, and Genome Assembly To achieve this goal, we defined the following objectives: (1) to generate full genome sequences from viral isolates obtained from outbreak cases within Nigeria as well as exported cases (2) to use genomic analyses to hypothesize relationships of exported cases to one another and to other viruses from the outbreak (3) to evaluate the exported variants temporally and spatially in the context of the broader outbreak and (4) to use these data to derive inferences regarding commonalities. A multidisciplinary approach was established to identify geographic and temporal trends, as well as possible links between cases to elucidate factors that might have contributed to the exportation of human MPX cases from Africa. The goal of this study was to better understand the relationship of exported cases in the context of the outbreak. The source of the 2003 United States (US) MPX outbreak was determined to be a shipment of rodents from West Africa. These exportations represent the first time a human host was documented to transfer MPXV from the African continent however, there are a handful of examples of MPX outbreaks in animals within laboratories and zoos with no clearly identified source of infection since it was first identified in 1958. Seven months later, a Nigerian national became ill with MPX in Singapore. No exported cases were reported for the first 11.5 months of the outbreak however, within a 3-week period from 2 to 23 September 2018, 3 unlinked travelers infected with MPXV left Nigeria and arrived in 2 countries. The largest West African MPX outbreak in history began in Nigeria in September 2017. Potential routes of exposure include interaction with wild animals and close proximity to sick individuals, as well as contact with infectious fomites. The West African clade is known to occur from western Cameroon to Sierra Leone, whereas the Congo Basin clade has been detected from central and southern Cameroon to the DRC. Based on serological data, MPXV is evidenced to be maintained by various mammalian species in endemic areas, with periodic introductions into human populations, where relatively short chains (≤7) of human-to-human transmission can occur. In the nearly 50 years since, human cases of MPX have been identified in 11 African countries and MPXV is considered endemic in the DRC. It is the etiological agent of the zoonotic disease monkeypox (MPX), which was first identified as a human pathogen in the Democratic Republic of the Congo (DRC, formerly Zaire) in 1970. Monkeypox virus (MPXV) is a species of large double-stranded DNA viruses belonging to the genus Orthopoxvirus.
