After being bitten by a dog, you should treat the wound immediately and get vaccinated against rabies. Rabies is by far the most common infectious disease with the highest mortality rate in humans, and the vast majority of cases are caused by bites or scratches from diseased dogs. Because dog bites can cause the body to be attacked by the rabies virus, rabies vaccination, a biological agent, can be effective in preventing rabies. Individuals who have been bitten by a dog should therefore be aware of the need for a full and timely rabies vaccination. After being bitten by a dog, an individual should seek medical attention in a timely manner. In addition to administering the rabies vaccine, a medical professional will disinfect the wound, stop the bleeding, and suture the wound according to the exposure conditions. Rabies itself is preventable, and individuals should be aware of the importance of knowing about it.
