Question

Rabies or hydrophobia is a ………………………..disease.
A. Viral
B. Bacterial
C. Protozoan
D. Helminths

Answer 1

Hint:- A pathogen is an infectious disease-causing agent that causes disease in humans as well as animals. Pathogens are generally microscopic and are very potent in causing conditions or illness. In some cases, the pathogenesis of the pathogen serves as fatal for the infected organism. Bacteria, viruses, and protozoans are all very important pathogenic groups that are known to cause several diseases.

Complete step-by-step solution :
Microscopic organisms such as bacteria, viruses are potential disease causing organisms and so are known as pathogens. A pathogenic organism is also referred to as germ and depends upon specific mode of transmission by one or various hosts.
Rabies is a viral disease and it is caused by the virus lyssavirus. A viral infection is often known as viral infection and takes place when the body of an organism is attacked and invaded by pathogenic virus species. The virus particles attach to the host cell and enter the susceptible cells of the host.
The disease rabies is caused by the pathogenic virus lyssavirus of the RNA virus of the family Rhabdoviridae. The virus is found in the saliva of the infected animals and spreads through bites or scratches of animals. The most common animals infected with this virus are the dogs. The infected animal then spreads the virus through biting other animals and humans. Humans usually are infected from the affected animal either through coming in contact with the saliva of the animal coming out from the mouth, eyes, nose, through scratches or even bites. It causes inflammation of the brain and infection occurs in the central nervous system in the mammals as well as the humans.
The diagnosis of the disease can be done after the onset of the symptoms. The most common symptoms include early symptoms such as fever and tingling sensation at the exposure area. The other symptoms include violent movements, uncontrolled and extravagant excitement, fear of water, confusion. In some cases, the prime symptom includes hydrophobia or fear of water with regular unconsciousness. The disease is marked by a high rate of mortality. The symptoms usually start from about one to three months after the infection.
Therefore, the correct answer is option A.

Note:- The virus lyssavirus is a highly infectious pathogenic virus causing rabies in animals as well as in humans. It spreads through the saliva or bites or scratches of the infected animal. The disease is characterized by fear of water or hydrophobia along with fever, unconsciousness and in the extreme case, can result in death.
