(D) A fungus
Answer: (B) A bacterium
Explanation: Lyme disease is caused by the bacterium Borrelia burgdorferi, transmitted to humans through the bite of infected blacklegged ticks.
Question 5
Which of the following is a control measure for vector-borne diseases?
(A) Vaccination of the human population
(B) Use of insecticides to control vector populations
(C) Improved sanitation and waste management
(D) All of the above
Answer: (D) All of the above
Explanation: A comprehensive approach to controlling vector-borne diseases includes targeting the pathogen, the vector, and the environment.
Question 6
What type of disease is Zika?
(A) Bacterial
(B) Viral
(C) Parasitic
