Stephen Higgs, director of the university’s Biosecurity Research Institute, is a world expert on the chikungunya virus. The Wichita Eagle (http://bit.ly/1oqeKRJ ) reports the name is an African Makonde word that means “to bend up,” with intense joint and body pain.

About 100 people in the United States have contracted the illness, most while traveling. Kansas Department of Health and Environment officials say they include two people from Sedgwick County who recently traveled separately to the Caribbean.

The danger here will be if infected travelers come home, get bitten, and infect local mosquitoes that could then spread the illness widely.
