Two North Carolina residents die from West Nile virus

Two North Carolina residents have died from West Nile virus, a disease spread by mosquitoes.

The state health department confirmed the deaths but did not release details about the people or where they lived.

The CDC reports 15 cases in North Carolina, while cases have been reported in 45 states.

West Nile virus is spread by Culex mosquitoes, and warmer temperatures, urban growth and global travel are helping mosquitoes and the disease reach more places.

Most people who get the virus have no symptoms or only mild illness, but about one in 150 cases becomes severe, potentially causing brain inflammation or paralysis.

Older adults and people with weakened immune systems or certain chronic conditions face a higher risk of severe illness.

Avoiding mosquito bites is the main prevention measure; health officials recommend repellent containing DEET, covering up outdoors and staying inside between dusk and dawn in summer.
