Hi, Welcome to HCM. No it is not true that a rabies patient barks like a dog, but he becomes very aggressive and suffers from hydrophobia. Hydrophobia is fear of water because trying to drink water can cause choking in him due to violent spasms of the throat muscles. other symptoms include aerophobia, anxiety, dilated pupils, fear, irritability, depression, perspiration and lacrimal secretion. He can later develop paralysis and die by 3rd to 7th day of infection. Rabies is a fatal disease and hence vaccination is compulsory when bitten by a rabid dog. Rabies infection is not transmitted sexually. Thanks.
