[Display omitted]This infographic describes the transmission cycle of rabies virus in domestic dogs and the necessity of a One Health approach, integrating medical and veterinary interventions, to control and eliminate human rabies deaths.Rabies virus (RABV) causes an acute, fatal neurological infection in humans and other mammals, transmitted through the saliva of rabid animals via a bite or scratch. From the site of infection the virus travels along neurons to the central nervous system (CNS), where viral replication leads to symptoms and systemic spread. Once symptomatic, the disease is nearly 100% fatal. However, the disease is 100% vaccine-preventable through the prompt administration of human postexposure prophylaxis (PEP) and vaccination of animal reservoirs. While RABV has a broad host range, domestic dogs cause over 99% of all human cases, killing 59000 people every year. Human PEP is costly (US$11–150 per dose) and often difficult to obtain. Dog vaccination is a considerably more cost-effective and feasible method to reduce the incidence of human rabies. With this in mind, the World Health Organisation (WHO) and partners have set a target for the global elimination of dog-mediated human rabies, through control of the disease in dogs, by 2030.
