Infectious Bovine Rhinotracheitis (IBR) is an infectious disease caused by herpesvirus type 1 (HVB-1) belonging to the genus Varicellovirus. Its distribution is worldwide, and it represents one of the principal causes of infertility and abortion in cattle, in addition to a decrease in production, causing economic losses. The infection can occur respiratory, conjunctival, vulvovaginal, with endemic abortions and septicemic form. Its transmission can be vertical and horizontal, in addition to having the ability to remain in a state of latency and then have periods of reactivation and re-excretion. The course and clinical manifestations of the disease depend on the anatomical site of infection, the age and the immune status of the carrier. The presumptive diagnosis of IBR can be made based on clinical, pathological, and epidemiological signs, but to make a definitive diagnosis, laboratory tests such as viral isolation, immunoperoxidase (IP), immunofluorescence (IF), serum neutralization, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) are required. Prophylaxis achieves by vaccination and the sacrifice of seropositive animals. The health and economic impacts of the RIB make it necessary to implement and reinforce national control programs and health training for ranchers, as well as progressive elimination of seropositive animals. For that reason, the objective was to review the IBR literature that allows addressing sanitary and epidemiological aspects of it.

La presente revisión tuvo como objetivo de identificar la importancia de la leptospirosis en la salud pública a través de un análisis de literatura en bases de datos a partir del año 2004 al 2019 para realizar un aporte teórico a este importante tema. Se dio a conocer las características de la bacteria Leptospira spp. y sus principales reservorios, la epidemiología y las prevalencias de la enfermedad, ubicaciones geográficas, las herramientas diagnósticas y el control y prevención de la leptospirosis. Se identificó cuantiosa información en cuanto a generalidades de leptospirosis y sobre el curso de la enfermedad, se denota la ausencia de información en varios sectores sociales para evitar su contagio, controlar la diseminación de la enfermedad, realizar diagnósticos tempranos y los pocos tratamientos para esta zoonosis.
