The ability to drink water does not necessarily exclude the possibility of rabies infection, fear of water is one of the more prominent symptoms of rabies, but the ability to drink water alone to exclude the possibility of rabies, but also need to be combined with medical history, clinical manifestations and auxiliary examinations to comprehensive analysis. 1, medical history: ask the person examined whether he or she has been scratched or bitten by a dog or other animal in recent times, whether there has been fear of wind, fear of water, fever and other reactions. If these medical histories exist, it means that the chance of rabies infection is greater than; 2. Clinical manifestations: rabies generally has an incubation period, a prodromal period, an excitement period and a paralysis period after the onset of the disease. In the incubation period the virus plays a smaller role, generally no specific performance; in the prodromal period will appear low fever, lethargy and throat tightness, similar to the signs of the flu; in the excitement period is generally manifested as a variety of fear symptoms, such as fear of water, fear of wind, more typical patients see water, drinking water, and even hear the sound of water will feel fear; in the paralysis period patients will gradually quiet, with limb flaccidity is most common. Therefore, the clinical symptoms of rabies are more complex, and the ability to drink water alone does not exclude the possibility of rabies infection; 3. Ancillary tests: If the diagnosis of rabies cannot be fully confirmed by questioning the medical history and clinical manifestations, immunological tests, cerebrospinal fluid tests and blood tests are also needed to assist in making the results more accurate.
