Question

Hydrophobia is a feature of which of the following diseases?
(a) Poliomyelitis
(b) Measles
(c) Rabies
(d) Hepatitis

Answer 1

Hint: This disease is mainly transmitted through an animal bite, for example, bite from stray dogs.

Complete answer:
Hydrophobia is also called "fear of water", it is the historic name for rabies. The symptoms are shown in the later stages of an infection in which the person has difficulty swallowing and a person shows panic when presented with liquids to drink and cannot quench their thirst. Any mammal infected with the virus should have hydrophobia. In their body, saliva production gets increased, so affected people will attempt to drink, which may cause very painful spasms of the muscles in the throat and larynx. Since the infected individual cannot swallow saliva and water, the virus has a much higher chance of being transmitted, since it multiplies and assimilates in the salivary glands and is transmitted through biting. 
Hydrophobia is commonly associated with furious rabies that is the second stage, which affects 80% of rabies-infected people. And the remaining 20% will face a paralytic form of rabies that is marked by muscle weakness, loss of sensation, and paralysis; this form of rabies does not usually cause fear of water. This sign occurs following paroxysmal contractions of pharynx responsible for hydrophobic spasms. Hydrophobia is shown in the dangerous phase of rabies because affected animals should be hyperreactive and bite others.
So, the correct answer is rabies.

Note: Other symptoms shown by infected people are fluctuating consciousness, modified mental state, aerophobia, phobic or inspiratory spasms, and autonomous stimulation signals. Death occurs usually 5.7 days on patients showing furious rabies after the first symptoms.
