As West Nile virus moves rapidly across the United States, doctors are recommending that people be more cautious about the mosquitoes buzzing around.

Mosquitoes infected with West Nile virus can pass the disease to humans. While human infection is rare, some people exposed to the virus suffer mild-to-moderate flu-like symptoms.

Dr. Elizabeth Race, an infectious diseases specialist at UT Southwestern Medical Center at Dallas, recommends using an insect repellent with a low percentage of DEET in it. A recent study found these insect repellents more effective than other repellents at keeping mosquitoes and other insects away. Parents should make sure the DEET percentage is low, Race says.

“Also, wear long pants and long-sleeved shirts when outdoors this summer, and avoid being outside at dawn or dusk when mosquitoes are most active,” she says.
