Map of Uganda showing the geographic location of Crimean-Congo hemorrhagic fever cases in relation to Sudan virus disease outbreak, September 2022- January 2023.
This map was created using QGIS, v 3.22.5, a free and open-source geographic information system available at: https://qgis.org/project/overview/. The Uganda map base layers were accessed from Humanitarian Data exchange v.1.83.2 (Uganda administrative boundaries - UGANDA BOUNDARIES SHAPEFILES AS OF 17 08 2018.zip - Humanitarian Data Exchange (humdata.org).

Fig 3.
Inferred evolutionary relationships for all available full length CCHFV genomes, including recent and historic CCHFV genomes from Uganda.
Historic (1956–2019) genomes are highlighted green, and recent (March-December 2022) genomes are highlighted blue. The S-segment phylogenetic tree contains two recent Ugandan-specific clades, in addition to a third clade containing two sequences from the 1950s and one from 2022. The M-segment phylogenetic tree includes Ugandan sequences split onto two clades. Two recent sequences (2022001211 and 2022005897) cluster with historic Ugandan sequences from the 1950s. While the L-segment phylogenetic tree includes a Uganda/DRC specific Africa 2 clade.
