The diagnosis of rabies is usually combined with clinical symptoms and a history of dog bites to make a comprehensive determination, and there is no laboratory facility that can confirm the diagnosis of rabies virus. Generally, symptoms of rabies may occur after about 1-3 months after being bitten by a rabid dog. The symptoms of rabies are mainly fear of wind, water and light, and a great deal of fear and restlessness. During the onset of rabies there will be extreme panic and even pharyngeal muscle spasms and a tendency to attack. Combining the dog bite with these symptoms of a very pronounced fear of water, light, and wind and pharyngeal muscle spasms, rabies can be diagnosed. Rabies is a lethal disease and is 100% fatal once it develops.
