Where did rabies come from?
Rabies is a fatal infectious disease caused by the rabies virus and is transmitted to humans primarily through bites or scratches from infected animals. In recent years, rabies has remained an important public health problem worldwide. This article will discuss the origin, transmission routes and preventive measures of rabies based on hot topics and hot content in the past 10 days.
1. The origin of rabies

| bite | dog, cat, fox | Clean wounds promptly and vaccinate |
| scratch | bat, raccoon | Avoid contact with wild animals |
| mucosal contact | wolf, jackal | Wear protective equipment |

| 2023-10-05 | Progress in the development of new rabies vaccines | Europe |
| 2023-10-10 | Rabies prevention and control publicity activities | Africa |
6. Summary
Rabies is an infectious disease with a long history and serious harm, but its transmission routes and preventive measures are relatively clear.
