The gross value of livestock production in Brazil in 2019 was estimated at R$ 213.9 billion. In the ranking of products, in first and second place were beef (R$ 101.5 billion) and milk (R$ 49.8 billion), respectively. Brazil as an exponent in the production of food of animal origin has the health of beef and dairy herds as a strategic asset for the country. In this regard, the existence of national animal health programs is essential for maintaining and improving the health of cattle herds. Another important point is that for certain diseases, some of these programs are designed based on the concept of one health, as they take into account animal health, human health and the environment. National animal health programs that are related to beef and dairy cattle are the National Program for the Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT) and the National Program for Rabies Control in Herbivores (PNCRH), both designed by the Ministry of Agriculture, Livestock and Supply (MAPA) and with the participation of the Official Veterinary Service (SVO) of the states in conducting the actions, together with the productive sector. The expansion of knowledge of veterinary epidemiology applied to infectious and parasitic diseases has been significant due to the great progress of information and communication technology (ICT) tools, software, databases and the ability to work in large databases that allow for epidemiological studies to be carried out. This information can assist at the state/region level of the state in disease control and prevention. In this regard, it is worth mentioning the importance of the Brazilian System of Veterinary Surveillance and Emergencies (SISBRAVET), one of MAPA's information management systems, which “talks” with the States' SVO. The objective of the project is to develop and validate ICT tools to support the SVO of the states of Rio de Janeiro and Minas Gerais in carrying out activities provided for in the PNCEBT and the PNCRH. In the case of the PNCEBT, after the veterinarian's qualification and registration, he/she can acquire biological inputs to carry out diagnosis and vaccination. However, it is necessary to send periodic reports on the consumption of biological inputs as well as the results of the exams. One of the project's innovations aims at the development and validation of an application/software to allow the veterinarian qualified in the PNCEBT to record the geographic coordinates of the herds submitted to diagnosis and vaccination and send the information requested by the SVO via the web aided by a agenda with alerts, as well as assist in the diagnosis of tuberculosis. This application/software aims to speed up, standardize and avoid errors in the calculations of the difference in skin thickness and clinical evaluations necessary to issue the result in the diagnosis of cattle tuberculosis and serve as input of information for the state and federal SVO (SISBRAVET). The application/software will be developed by the technical and ICT teams of Embrapa Dairy Cattle, Federal Laboratory of Agricultural Defense (LFDA/MG), Minas Gerais Institute of Agricultural Technology (IMA) and Secretary of Agricultural Defense of the State of Rio de Janeiro. In the case of PNCRH, MAPA has asked the SVO of the states to develop maps with identification of risk areas for rabies, as well as the areas of shelter for hematophagous bats notified to the SVO. The cases of rabies in cattle and the shelters of hematophagous bats must be registered and monitored periodically in order to maintain a reliable georeferenced database for spatial analysis of risk areas for rabies and hematophagous bats. Information related to the geographic coordinates of cases of rabies as well as the number of cases will be made available on SISBRAVET. Another innovation proposed in the project is the development and periodic validation of maps showing risk areas for rabies in the states of Minas Gerais and Rio de Janeiro with information from the state SVO database. The project also has partnerships with the Federal University of Minas Gerais (UFMG), the Federal University of Viçosa (UFV) and the Fluminense Federal University (UFF).
