Abstract Bussuquara virus (BSQV) was first discovered in the Brazilian Amazon in 1956 . It is an arthropod-borne virus (arbovirus) in the genus Orthoflavivirus , family Flaviviridae . Since its discovery, BSQV has been sporadically detected across the South ( Brazil, Columbia, and Argentina ) and Central ( Panama and Mexico ) America and the Caribbean ( Grenada ), but there is minimal BSQV surveillance due to limited public health awareness and a lack of specific or sensitive diagnostics. BSQV exposure has been reported in a wide range of host and vector species , including humans . Little information is available in the literature and herein we summarize the published historical findings on BSQV and suggest a pathway for future studies to better understand its potential emergence into human populations.

Abstract The European subtype of tick-borne encephalitis virus (TBEV-Eur; species Orthoflavivirus encephalitidis , family Flaviviridae ) was the only tick-borne flavivirus present in central Europe known to cause neurologic disease in humans and several animal species . Here, we report a tick-borne flavivirus isolated from Alpine chamois (Rupicapra rupicapra rupicapra) with encephalitis and attached ticks , present over a wide area in the Alps . Cases were detected in 2017 in Salzburg, Austria , and 2023 in Lombardy and Piedmont, Italy . The virus strains exhibit 94.8–97.3% nucleotide identities to each other and are more closely related to Louping ill viruses (LIV; Orthoflavivirus loupingi ; 90–92% identities) than to TBEV-Eur (less than 88%). The chamois-derived virus strains, tentatively termed “ Alpine chamois encephalitis virus ”, form a well-supported independent genetic clade with Spanish goat encephalitis virus , clearly separated from other LIV. This supports its designation a...
