Answer 1

Correct Answer - Option 4 : Rabies

The correct answer is Rabies.

Disease	Caused by
Rabies	It is caused by the rabies virus. The virus is spread through the saliva of infected animals. Infected animals can spread the virus by biting another animal or a person. In rare cases, rabies can be spread when infected saliva gets into an open wound or the mucous membranes, such as the mouth or eyes. A deadly virus spreads to people from the saliva of infected animals. Rabies is usually transmitted through an animal bite, for example, from stray dogs. Symptoms include fever, headache, excess salivation, muscle spasms, paralysis, and mental confusion. Seek immediate medical attention after a bite or suspected bite. There is no specific treatment for rabies. Once symptoms appear, it's nearly always fatal. A vaccine can prevent infection.
Typhoid	It is caused by the bacterium SalmonellaTyphi. It is usually spread through contaminated food or water.
Leukemia	Leukemia is a blood cancer caused by a rise in the number of white blood cells in your body. Those white blood cells crowd out the red blood cells and platelets that your body needs to be healthy.
Filaria	Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection occurs when filarial parasites are transmitted to humans through mosquitoes. Lymphatic filariasis is caused by infection with parasites classified as nematodes (roundworms) of the family Filariodidea Lymphatic filariasis impairs the lymphatic system and can lead to the abnormal enlargement of body parts, causing pain, severe disability.
