Hydrophobia is mostly attributed to rabies, most of the sources refer rabies as hydrophobia. Technically Hydrophobia is the intense fear of water.




  Hydrophobia is an intense, irrational fear of water that can be commonly diagnosed at childhood and should be treated as soon as possible. Certain types of hydrophobia may also appear in later stages of contracting rabies, which would require treatment on an immediate basis.


Also the Wikipedia link for Rabies states that


  Signs and symptoms may soon expand to slight or partial paralysis, anxiety, insomnia, confusion, agitation, abnormal behavior, paranoia, terror, and hallucinations, progressing to delirium. The person may have hydrophobia.


So rabies and hydrophobia are distinct and hydrophobia is a symptom of rabies.


  Hydrophobia may, however, more readly be confronted with hysteria, acute mania and tetanus.


Hydrophobia is incidental to other diseases, it can be observed, occassionally, in tetanus,hysteria,cynanche,tonsillaris,tracheitis and certain inflammations in stomach. Tetanus is strongly believed to cause intense hydrophobia conditions.How ever, there is always a belief of hydrophobia linked with rabies.


  The pathology of Hydrophobia and Tetanus is found to have great similarities and there is a great similarity in the distribution of lesion in the central nervous system as well as a certain analogy in the kind of lesion. The special localization of symptoms of both disease, in the tongue,throat and neck was associated with the special prevalence of the lesions in the medulla oblongata and especially in the neighborhood of the nuclei in the fourth ventricle etc.

So it is possible to cause hydrophobic conditions when Tetanus is affected and also hydrophobia can occur from mental disorders.
