Health officials announced the closure of two additional Bay Area schools Sunday due to the H1N1 flu, one in Mill Valley and one in Berkeley.
A student at Tamalpais High School in Mill Valley who contracted the county's fourth confirmed case of the H1N1 virus has prompted the school's closure for a week, Marin County Sheriff's Office of Emergency Services Sgt. Debra Barry said Sunday morning.
The student recently traveled to Mexico and is recovering from the virus at home, according to Barry.
A 35-year-old Novato man was the county's third confirmed case, and a 60-year-old woman and her 20-month-old granddaughter were the county's first two, according to Barry.
Bahia Vista Elementary School in San Rafael announced its closure Friday after a student contracted a probable case of the H1N1 virus, Barry said. The student's test results are pending.
The closure of Malcolm X Elementary School in Berkeley was announced Sunday as well due to a probable case of the virus, Berkeley Health and Human Services Department spokeswoman Zandra Lee said.
At least 10 schools have also been closed in Contra Costa and Santa Clara counties in connection with the H1N1 virus.
Brentwood Elementary School in Brentwood, Coyote Creek Elementary School in San Ramon, Shores Acres Elementary School in Bay Point, Lone Tree Elementary School in Antioch and Highlands Elementary School in Pittsburg were closed due to probable cases of the virus.
Branham High School, Challenger School, Delphi Academy, Elan Espirit Preschool and Rucker Elementary School were closed due to H1N1 cases as well.
As of Sunday afternoon, there have been 226 confirmed cases of the H1N1 virus in the U.S. and one death related to the illness, according to the Centers for Disease and Control Prevention.
