Travel-associated international spread of Oropouche virus beyond the Amazon
Iani, Felipe Campos de Melo; Pereira, Felicidade Mota; Oliveira, Elaine Cristina de; Rodrigues, Janete Taynã Nascimento; Machado, Mariza HoffmannOropouche virus (OROV), first detected in Trinidad and Tobago in 1955, was historically confined to the Brazilian Amazon Basin. However, since late 2022, an increasing number of OROV cases have been reported across various regions of Brazil as well as in urban centers in Bolivia, Ecuador, Guyana, Colombia, Cuba, Panama, and Peru. In collaboration with Central Public Health Laboratories across Brazil, we integra...
Dengue virus importation risks in Africa: a modelling study
Poongavanan, Jenicca; Lourenço, José; Tsui, Joseph L.H.; Colizza, Vittoria; Ramphal, Yajna; Baxter, Cheryl; Kraemer, Moritz U. G.; Dunaiski, MarcelBackground: Dengue is a significant global public health concern that poses a threat in Africa. Particularly, African countries are at risk of viral introductions through air travel connectivity with areas of South America and Asia in which explosive dengue outbreaks frequently occur. Limited reporting and diagnostic capacity hinder a comprehensive assessment of continent-wide transmission dynamics and deployme...
Integrated analyses of the transmission history of SARS-CoV-2 and its associati...
Cella, Eleonora; Fonseca, Vagner; Branda, Francesco; Tosta, Stephane; Moreno, Keldenn; Schuab, Gabriel; Ali, Sobur; Slavov, Svetoslav NanevBackground: Italy was significantly affected by the COVID-19 pandemic, experiencing multiple waves of infection following the sequential emergence of new variants. Understanding the transmission patterns and evolution of SARS-CoV-2 is vital for future preparedness. Methods: We conducted an analysis of viral genome sequences, integrating epidemiological and phylodynamic approaches, to characterize how SARS-CoV-2...

Urgent need for a non-discriminatory and non-stigmatizing nomenclature for monk...
Happi, Christian; Adetifa, Ifedayo; Mbala, Placide; Njouom, Richard; Nakoune, Emmanuel; Happi, Anise; Ndodo, Nnaemeka; Ayansola, OyeronkeWe propose a novel, non-discriminatory classification of monkeypox virus diversity. Together with the World Health Organization, we named three clades (I, IIa and IIb) in order of detection. Within IIb, the cause of the current global outbreak, we identified multiple lineages (A.1, A.2, A.1.1 and B.1) to support real-time genomic surveillance.
Tracking the international spread of SARS-CoV-2 lineages B.1.1.7 and B.1.351/50...
O'Toole, Áine; Hill, Verity; Pybus, Oliver G.; Watts, Alexander; Bogoch, Issac I.; Khan, Kamran; Messina, Jane P.; Tegally, HouriiyahLate in 2020, two genetically-distinct clusters of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with mutations of biological concern were reported, one in the United Kingdom and one in South Africa. Using a combination of data from routine surveillance, genomic sequencing and international travel we track the international dispersal of lineages B.1.1.7 and B.1.351 (variant 501Y-V2). We account f...
