Abstract :
Background: Rift Valley Fever (RVF) is a
vector-borne zoonosis that severely affects different
species of domestic and wild ruminants and humans.
RVF is on the list of diseases to be notified to the World
Organization for Animal Health due to its zoonotic
nature and its economic importance, linked to direct
losses in animals and restrictions on animal trade. on feet
resulting from the declaration of outbreaks.
Methods : A retrospective analytical cross-sectional
study in livestock in Mauritania, on RVF surveillance
data in 2020. The study population consists of all the
animals sampled and analyzed in the virology laboratory
at the National Office of Livestock Research and
Development in Nouakchott during the year 2020. The
analysis was carried out using Epi-info® 7.4 and the
Excel® 2019 spreadsheet. Proportions, frequencies, ORs
with their 95% CI and P value were calculated. The
results were presented in the form of tables and figures.
Results : Out of 1110 notified cases of RVF in cattle, 208
cases were confirmed including 94 camels (45.19%), 55
goats (26.44%), 39 sheep (18.75%) and 20 cattle (9.
62%). The age group from 0 to 5 years was the most
represented (735/1110), or 52.2% of cases, and 359/1110,
or 32.34% of cases were between 6 and 9 years old. The
average age was 4.6 years. RVF foci are more observed
in the regions of Tagant, Brakna, Trarza and Hodh
Chergui. The RVF varied significantly (p<0.05) with the
state of rainfall, the state of the ponds and the mosquito
pressure.
Conclusion: The overall prevalence of RVF in the
country was 17.24%. The highest prevalence was
recorded in the regions of Tagant, Assaba, Trarza and
Hodh Chargui. Multivariate analysis revealed that there
is a significant association between rainfall status, pond
status and mosquito pressure with RVF seropositivity.
