Which insect is responsible for transmitting lice?

  1. Fleas

  2. The body or head louse

  3. Bed bugs

  4. Ticks

The correct answer is: The body or head louse

The body or head louse is the correct answer because these specific insects are known for directly causing lice infestations in humans. Lice are parasitic insects that live on the scalp (head lice) or on the body (body lice), feeding on human blood and laying eggs in the hair or on clothing. They are a significant concern in terms of public health due to their ability to spread easily through close contact and infested items. Fleas, bed bugs, and ticks do not transmit lice; instead, they are distinct types of insects that pose different health risks. Fleas primarily infest pets but can bite humans and cause skin irritation. Bed bugs are known for living in mattresses and furniture, feeding on human blood at night. Ticks are associated with illnesses like Lyme disease but are not involved in the transmission of lice. Understanding these differences is important for identifying and addressing the specific issues related to lice infestations versus those caused by other pests.
