Lassa and Crimean-Congo Hemorrhagic Fever Viruses, Mali

Jan Baumann et al. Emerg Infect Dis. 2019 May.

Abstract

We report detection of Lassa virus and Crimean-Congo hemorrhagic fever virus infections in the area of Bamako, the capital of Mali. Our investigation found 2 cases of infection with each of these viruses. These results show the potential for both of these viruses to be endemic to Mali.

Keywords: Bamako; CCHFV; Crimean-Congo hemorrhagic fever virus; LASV; Lassa virus; Mali; hemorrhagic fever; viruses.

Figure 1
Phylogenetic analysis of representative Lassa virus (LASV) isolates identified in Mali in 2016 (bold) and reference isolates. The tree was constructed by using full-length sequences of the small RNA segment and the neighbor-joining method with bootstrapping to 10,000 iterations. Partial sequences were compared by using the pairwise deletion method. The tree is drawn to scale. Evolutionary analyses were conducted in MEGA7 (https://www.megasoftware.net). Scale bar indicates nucleotide substitutions per site.

Phylogenetic analysis of representative Crimean-Congo hemorrhagic fever virus (CCHFV) isolates identified in Mali in 2017 (bold) and reference isolates. The tree was constructed by using full-length sequences of the small RNA segment and the neighbor-joining method with bootstrapping to 10,000 iterations. Partial sequences were compared by using the pairwise deletion method. The tree is drawn to scale. Evolutionary analyses were constructed in MEGA7 (https://www.megasoftware.net).
