Health officials in Las Vegas say four more school-age children and one adult tested positive for swine flu virus, bringing the number of confirmed cases in Nevada to 21.
The Southern Nevada Health District reported Wednesday that a 5-year-old girl; boys ages 7, 10, and 14, and a 45-year-old woman each had a mild form of the H1N1 virus. Three have fully recovered. None required hospitalization.
The Clark County School District identified four northern Las Vegas Valley schools -- Saville and Cadwallader middle schools and Arbor View and Legacy high schools -- as having students with the swine flu virus.
The schools will not be closed, but the district is sending out letters to inform parents and ask families to take precautions, such as frequently washing hands and keeping children home if they're sick.
Saville is at 8101 N. Torrey Pines Drive near Grand Teton Drive; Cadwallader is at 7775 Elkhorn Road near Buffalo Drive; Arbor View is at 7500 Whispering Sands Drive near Buffalo Drive; and Legacy is at 150 W. Deer Springs Way near Commerce Street.
Another school, Findlay Middle School at Tropical Parkway and Commerce Street, was identified last week as having a student with the swine flu virus.
Health officials previously reported nine swine flu cases in Clark County, four in Reno, two in Carson City and one in Lyon County.
