Rabies is an acute infectious disease that occurs when a person is bitten by a dog, cat, wolf or other animal and becomes infected with rabies virus, which can multiply in the salivary glands of the dog and infect the person through residual saliva from the wound after the bite. The main manifestations of the disease in humans are excitement, fear of water, pharyngeal muscle spasm, respiratory distress and progressive paralysis until death. The incubation period is 20-90 days, once the onset of treatment there is no specific drugs, the death rate is very high almost 100%. Typical mad dog often shows two ears upright, eyes straight, red eyes, salivation, thinning, barking and running, see people bite, walking unsteadily; there are a few mad dog performance quiet, away from the group alone, a disturbed, barking, tongue salivation. Until the whole body paralysis and death. Some dogs and cats, although not “rabies” performance, but with rabies virus, they bite people can still make people infected with rabies virus and get “rabies”. Therefore, people bitten by dogs or cats, regardless of whether the time can be sure that the mad dog, must be the following method of timely wound treatment: if the wound bleeding, as long as not bleeding too much, do not rush to stop the bleeding, because the blood flow will be the wound residual mad dog saliva washed away, natural can play a certain role in disinfection. For wounds that do not bleed much, the bleeding should be squeezed from the proximal end to the wound to facilitate detoxification. At the same time, the wound must be thoroughly cleaned as early as possible within two hours after the injury to reduce the chance of rabies. Use a clean brush, either a toothbrush or gauze, and concentrated soapy water to repeatedly brush the wound, especially the deep part of the wound, and rinse it with water promptly, not refusing to brush carefully because of pain, and the brushing time should last at least 30 minutes. After rinsing, then use 70% alcohol or 50 degrees – 70 degrees of white wine to rub the wound several times, in the absence of anesthesia, the pain is more obvious when rubbing, the wounded should be psychologically prepared. After the rubbing is completed, the wound does not need to be bandaged and can be left bare. For other parts of the dog scratched, licked and sucked, as well as saliva contamination of the old and new wounds, should be treated as the same as bite wounds. After the above wound treatment, the casualty should be sent to a nearby hospital or health prevention station to receive rabies vaccine as soon as possible.
