In contrast, domestic ruminants and camelids remain asymptomatic. Since the first reported case in Mauritania in 1983, CCHFV antibodies have been repeatedly detected in humans and animals. This study aimed to assess the local circulation of CCHFV in camels and cattle in southern Mauritania and in Nouakchott.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A total of 317 blood samples (174 cattle, 143 camels) were collected from southern regions bordering Mali and Senegal (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009170) and from Nouakchott (slaughterhouse and animal market;\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009147).

Strengthening diagnostic capacity, conducting integrated epidemiological studies across livestock, ticks and humans, and enhancing awareness and regional surveillance are essential for a better
