Zoonotic diseases, also known as zoonoses, are infectious diseases that can be transmitted from animals to humans or vice versa. These diseases are of significant concern to public health as they can cause severe illness, and in some cases, death, so early detection and diagnosis are crucial for effective treatment and prevention. The study was conducted from July 2022 to July 2023 to test suspected samples of both human and animal populations for various common zoonotic diseases at district surveillance laboratories and district veterinary surveillance laboratories, respectively, in Haryana state. Zoonotic diseases such as tuberculosis, paratuberculosis, salmonellosis (typhoid), brucellosis, leptospirosis, and scrub typhus were included in the present study. Out of 25,911 animal samples, 216 were positive for brucellosis as detected through ELISA. None of the samples were found positive for bovine tuberculosis and bovine paratuberculosis. Out of 13,693 suspected human samples, 2,048 were positive for human tuberculosis, and among 22,750 samples, 3884 were positive for salmonellosis. For scrub typhus, 15 out of 99 samples were positive, while 4 out of 70 were positive for leptospirosis. The diagnosis of zoonotic diseases is a complex process that requires a multidisciplinary approach. Early diagnosis and prompt treatment of these diseases are essential for ensuring optimal health outcomes and preventing the spread of these zoonotic diseases to humans and animals.
