Which of the following is a non-arthropod borne disease :-

The correct answer is (c), Tetanus.

Malaria and dengue are both arthropod-borne diseases, meaning they are transmitted to humans by mosquitoes. Tetanus, on the other hand, is a non-arthropod-borne disease, meaning it is not transmitted by insects. Tetanus is caused by a bacterium called Clostridium tetani, which can enter the body through cuts or wounds. Once inside the body, the bacteria produce a toxin that causes muscle stiffness and spasms. Tetanus can be fatal if not treated promptly.

Here is a brief description of each option:

• Malaria is a mosquito-borne disease caused by a parasite called Plasmodium. The parasite is transmitted to humans when an infected mosquito bites them. Malaria can cause fever, chills, anemia, and death.
• Dengue is a mosquito-borne disease caused by a virus. The virus is transmitted to humans when an infected mosquito bites them. Dengue can cause fever, headache, muscle aches, and rash. In severe cases, dengue can cause bleeding and shock.
• Tetanus is a non-arthropod-borne disease caused by a bacterium called Clostridium tetani. The bacterium can enter the body through cuts or wounds. Once inside the body, the bacteria produce a toxin that causes muscle stiffness and spasms. Tetanus can be fatal if not treated promptly.
