Ans: B, D
Feedback:
WNV virus is not transmitted from person to person but from mosquito to person. No isolation precautions are indicated other than standard precautions. The Centers for Disease Control and Prevention (CDC) guidelines emphasize avian, animal, mosquito, and human WNV surveillance, along with control and elimination of mosquito breeding sites such as standing water in flowerpots, buckets, and old tires. The CDC recommends using an insect repellent such as DEET (N, N-diethyl-m-toluamide) or picaridin when outdoors, following the directions on the package. Because mosquitoes are most active at dusk and dawn, in addition to an insect repellent, people should wear long sleeves and pants when outdoors during these hours. Screens on windows and doors will keep mosquitoes out.
