what are symptoms of rabies in humans?

Answer 1

it is very bad!
a child may develop a fever, headache, and general malaise. A twitching around the animal bite, a trademark symptom of rabies, may appear in addition to a fever above 105 degrees Fahrenheit (40.5 degrees Celsius), agitation, and hallucinations.

Most victims suffer excruciating pain on swallowing liquids. Though they suffer from thirst, animal and human rabies victims can be terrified by the sight of water, hence another name for the disease, hydrophobia

The period between infection and the first flu-like symptoms is normally two to twelve weeks, but can be as long as two years. Soon after, the symptoms expand to slight or partial paralysis, cerebral dysfunction, anxiety, insomnia, confusion, agitation, abnormal behavior, paranoia, hallucinations, progressing to delirium. The production of large quantities of saliva and tears coupled with an inability to speak or swallow are typical during the later stages of the disease; this can result in "hydrophobia", where the victim has difficulty swallowing, shows panic when presented with liquids to drink, and cannot quench their thirst. The disease itself was also once commonly known as hydrophobia, from these characteristic symptoms. Death almost invariably results two to ten days after the first symptoms; the few humans who are known to have survived the disease were all left with severe brain damage, with the recent exception of Jeanna Giese.

Answer 2

In rabies, once neurological symptoms appear, the disease is fatal. No cure.
So anytime there is an animal bite and the possibility of rabies exists, treatment should be undertaken immediately.
