Question

what should countries across the world limit to prevent the spread of malaria?
○ food that is undercooked
○ bites from infected insects
○ contact with infected birds
○ contaminated drinking water

Explanation:

Malaria is a mosquito - borne disease. Mosquitoes (infected insects) are the vectors that transmit the malaria parasite. Limiting bites from infected insects (mosquitoes) is a key preventive measure. Undercooked food is more related to food - borne illnesses like some bacterial or parasitic infections (not malaria). Contact with infected birds is relevant for diseases like avian influenza. Contaminated drinking water is associated with water - borne diseases such as cholera, not malaria.

Answer:

bites from infected insects
