Yellow fever – Brazil

Brazil is currently in the seasonal period for yellow fever, which occurs from December through May. The expansion of the historical area of yellow fever transmission to areas in the south-east of the country in areas along the Atlantic coast previously considered risk-free led to two waves of transmission (Figure 1). One during the 2016 –2017 seasonal period, with 778 human cases, including 262 deaths, and another during the 2017–2018 seasonal period, with 1376 human cases, including 483 deaths. From December 2018 through January 2019, 361 confirmed human cases, including eight deaths, have been reported in 11 municipalities of two states of Brazil. In the southern part of S ão Paulo state, seven municipalities:El dorado (16 cases), Jacupiranga (1 case), Iporanga (7 cases), Cananeia (3 cases), Cajati (2), Pariquera-Açu (1), and Sete Barras (1) reported confirmed cases. In the same state, additional cases in Vargem (1) and Serra Negra (1) municipalities were confirmed on the border with Minas Gerais State. Additionally, two cases have been confirmed in the municipalities of Antonina and Adrianópolis, located in the eastern part of Paraná State. These are the first confirmed yellow fever cases reported since 2015 from Paraná, a populous state with an internatio nal border. Among these confirmed cases, 89% (32/36) are male, the median age is 43 years, and at least 64% (23/36) are rural workers.

An outbreak of yellow fever in Brazil made it possible to assess different presentations of disease such as perinatal transmission. A pregnant woman was admitted to hospital with yellow fever symptoms. She was submitted to cesarean section and died due to fulminant hepatitis. On the sixth day, the newborn developed liver failure and died 13 days later. Yellow fever polymerase chain reaction was positive for both.

We present POLICI (POpulation-Level Immunization Coverage - Imperial), an interactive online tool for visualising and extracting YF vaccination coverage estimates in Africa. We calculated single year age-disaggregated sub-national population-level vaccination coverage for 1950-2050 across the African endemic zone by collating vaccination information and inputting it into a demographic model. This was then implemented on an open interactive web platform. POLICI interactively displays age-disaggregated, population-level vaccination coverages at the first subnational administrative level, through numerous downloadable and cus...

Non-malarial febrile illness outbreaks were documented in 2007 and 2010 in Gabon. After investigation, these outbreaks were attributed to the chikungunya and dengue viruses (CHIKV and DENV). However, for more than half of the samples analyzed, the causative agent was not identified. Given the geographical and ecological position of Gabon, where there is a great animal and microbial diversity, the circulation of other emerging viruses was suspected in these samples lacking aetiology. A total of 436 undiagnosed samples, collected between 2007 and 2013, and originating from 14 urban, suburban, and rural Gabonese locations wer...

Abstract In November 2018, yellow fever was diagnosed in a Dutch traveller returning from a bicycle tour in the Gambia-Senegal region. A complete genome sequence of yellow fever virus (YFV) from the case was generated and clustered phylogenetically with YFV from the Gambia and Senegal, ruling out importation into the Netherlands from recent outbreaks in Brazil or Angola. We emphasise the need for increased public awareness of YFV vaccination before travelling to endemic countries. PMID: 30696531 [PubMed - in process]
