SUMMARY:

Rabies is a serious and potentially fatal infectious disease that affects mammals,
mainly dogs, but also other species of animals. It is caused by the rabies virus, a
virus of the genus Lyssavirus and family Rhabdoviridae, transmitted through
infected saliva, usually through a bite. Rabies is considered endemic worldwide,
with a higher incidence in Africa, Asia and Latin America. The objective of this work
is to describe epidemiological aspects of rabies in mammalian species in the state
of Rio Grande do Norte (2005 - 2021). The records and notes book of the Animal
Rabies Diagnosis Sector - LACEN/RN and the Laboratory Environment Manager -
GAL were used as a source of information. In the period between october 2005
and december 2021, 5,649 samples were sent for rabies laboratory analysis at
LACEN/RN, 5,632 samples from non-human mammals and 17 samples from
humans suspected of rabies. Of the total number of samples from non-human
mammals sent for diagnosis, 611 (10.8%) were positive for rabies. In the same
period, a human sample was diagnosed positive for rabies (5.89%). Considering
the studied species, samples of 2,507 bats were analyzed and 416 (16.6%) were
positive for rabies. A total of 1647 specimens from domestic canines were

examined and 17 (1.03%) were positive. Additionally, 688 samples of domestic
felines were studied, and of these, four (0.59%) were positive. In the context of
cattle, 148 were analyzed, and of these, 92 (62.20%) were positive. A total of 105
samples from foxes were studied and 59 (56.11%) were positive. As for the horses,
47 were studied and 17 (36.18%) were positive. Of the 18 sheep analyzed, two
(11.11%) were positive. Of the 17 human samples, one (5.89%) was positive. Of
the 11 pigs analyzed, three (27, 28%) were positive for rabies. Of the three
donkeys analyzed, 01 (33.33%) was positive. Of the 417 samples analyzed from
non-human primates (NHP), 31 opossums and 10 goats, none were positive for
rabies. From this study, we can conclude that the rabies virus is circulating in
mammals in the state of Rio Grande do Norte, Brazil, and because it is a neglected
zoonosis with unique and complex epidemiological characteristics, it deserves
more attention and study.
