This study had the aim of describing an outbreak of yellow fever that occurred in the municipalities under the jurisdiction of the Regional Healthcare Administration of Diamantina, Minas Gerais, between 2002 and 2003, in which 36 cases were notified. This was an autochthonous outbreak of wild-type yellow fever. Failure of vaccinal coverage and low levels of detection of mild cases were found. Among the cases, 33 (91.7%) were male and the age range was from 16 to 67 years. Nineteen (52.8%) of the cases were classified as severe and 12 men (33.3%) died of the disease. All of the cases came from rural areas and presented fever, headache, vomiting, jaundice, myalgia, oliguria and signs of hemorrhage. Surveillance through laboratory tests was the determining factor in diagnosing the outbreak. By describing the epidemiological and clinic findings, this study contributes towards diagnosing and classifying this disease. It was deduced that there is a relationship between deforestation, and outbreaks, and that there is a potential regional risk of yellow fever because of the local development of tourism.

Yellow fever (YF) is a viral disease endemic to the tropical regions of Africa and South America. An outbreak of YF has been occurring in Angola, since the beginning of 2016. In March 2016, a 32-year-old Chinese man who returned from Angola was hospitalized and diagnosed with the first case of imported YF in China. Clinical observations, blood viral RNA detection, serological testing and treatments for the patient were performed daily. The virus was isolated in Vero cells, and the complete viral genome was sequenced and analyzed using the next-generation genomic sequencing platform. The patient presented with hemorrhagic fever, jaundice and oliguria at day 3 after onset, which rapidly progressed to multisystem organ failure with extremely elevated liver, pancreatic and myocardial enzymes. The patient died despite the intensive supportive treatments that were performed. A liver biopsy showed severe and multilobular necrosis. Viral RNA was detectable throughout the clinical course of the disease. Whole-genomic sequence analysis revealed that the virus belongs to the Angola71 genotype. Although the virus has been circulating in Angola for 45 years, only 14 amino-acid substitutions and no amino-acid changes were observed in the membrane and envelope proteins compared with the virus collected in 1971. The presence of this imported YF case in China indicated that with the increase in business travel among countries, YF outbreaks in Africa can lead to the international spread of the disease. The production and use of YF vaccines is, therefore, an urgent issue.
