Rabies is a disease which is caused when the infected animal bites the human. Rabies is a disease which is caused by the rabies virus. The vaccine for the treatment of the rabies was first developed by Louis Pasteur and Roux. This vaccine was developed in the year 1885 and was injected into a kid who was infected with rabies due to the dog bite.

Rabies or hydrophobia is a viral disease that causes inflammation of the brain in humans and other mammals. Early symptoms include fever and tingling at the site of exposure. The other symptoms include violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Hence, rabies is caused by the rabies virus.

Rabies is a zoonotic disease with a wide range of mammalian reservoirs. Option C provides the most comprehensive list of animals known to carry the virus.

Hydrophobia, also known as rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Early symptoms can include fever and tingling at the site of exposure. Rabies virus is typically transmitted to humans by the bite of an infected mammal, often a carnivore or a bat. If rabies is untreated properly, 100% fatality rate is associated with infection. 

Rabies is a major public health problem in India. The disease occurs in all parts of the country except Lakshadweep islands because of lack of dogs (vector of rabies virus) in that particular region. About 7-10 thousand cases are reported every year. About 30,000 persons contract rabies and die; more than 2 million people are exposed to animals every year and about 1 million are administered anti-rabies vaccines.

Vaccines are the suspension of the live or killed microorganism which mainly activates the immune response. Louis Pasteur produced the first vaccine for rabies by growing the virus in rabbits. Pasteur was the first scientist to artificially attenuate viruses for use in vaccines. He created several veterinary vaccines before his development of the rabies vaccine in 1885 for use in humans. So, the correct answer is option C.

Zoonotic disease refers to an infectious disease, and it can be passed directly or indirectly between species such as from vertebrate animals to humans. It is transmitted to humans is rabies, and humans acquire this disease from animals (dogs, cats and monkeys). The disease (rabies)-causing agent is a virus.

Explanation: Any warm-blooded animals, domestic or wild, can carry rabies. Other animals such as birds, reptiles, amphibians, or fish neither contract rabies nor pass on the virus.

Explanation: Symptoms usually appear 30 to 90 days after exposure. Depending on the severity of the bite and the place on the body that was bitten, symptoms may appear more quickly. In rare cases, however, a person may not develop symptoms until a year or more after exposure.

Explanation: In humans it may take from as early as two weeks to as late as one year after exposure for symptoms to appear.
