Abstract: Anthropogenic environmental changes arising from settlement and agriculture include deforestation and replacement of natural vegetation by crops providing opportunities for pathogen spillover from animals to humans. This study aimed to investigate the prevalence of rodent-borne virus infections in seven rural settlements from Midwestern Brazil. Of the 466 individuals tested 12 (2.57%) were reactive for orthohantavirus and 3 (0.64%) for mammarenavirus. These rural settlers lived under unfavorable infrastructure… Show more

“…It is noteworthy that five of the six individuals with antibodies against mammarenavirus mentioned that they performed hunting and fishing for their livelihood. No significant association was found between mammarenavirus seropositivity and work activities or other variables ( Table 1), probably because of the low seroprevalence ratio, however, the prevalence observed was higher than those found in other previous studies that were conducted in Brazil and Colombia 6,10,13 .…”

“…Blood samples were collected during a cross-sectional survey in 2004 and were stored in a -20 °C freezer 9 . In total, 206 serum samples were subjected to serological analysis using the enzyme-linked immunosorbent assay (ELISA), according to a previously published protocol 10 . Antigens were derived from the Vero C76 cells (ATCC ® CRL-1587™) infected with Junín mammarenavirus (Clade B New World mammarenaviruses) or Maciel orthohantavirus (Andes orthohantavirus group).…”

“…The first report of hantavirus in Brazil dates from 1993, when Juquitiba virus, transmitted by Oligoryzomys nigripes, was detected by Silva et al (1997) 73 . To date, the following viruses have been identified in the country: (a) Araraquara virus (transmitted by Necromys lasiurus rodents); (b) Castelo dos Sonhos virus (Oligoryzomys utiaritensis); (c) Laguna Negra virus (Calomys callidus); (d) Anajatuba virus (Oligoryzomys mattogrossae); and Rio Mamore virus (Oligoryzomys microtis), among others 20 .…”

“…Wild rodents are reservoirs for hantavirus, vaccinia virus, and Lassa virus, among others [16][17][18][19] . 20 investigated rural settlements in Goiás (Brazil), and found 2.57% (n=12) positive rate for Orthohantavirus, equally distributed between women and men (n=6). In contrast, similar studies showed higher frequency in middle-aged men due to their risk behaviors 21,22 .…”
