Chicken Pox Outbreak Hits South Bay School

Nearly a dozen students at a Chula Vista elementary school have been diagnosed with chicken pox, according to county health officials.

The outbreak affects 11 students at Joseph Casillas Elementary.  The County of San Diego Health and Human Services Agency (HHSA) said the infected students included one third grader, nine fifth graders and one sixth grade student. Ten of the infected students had one dose of the chicken pox vaccine. One student had two doses.

Health officials said the total number of students diagnosed with the disease could climb because another 12 students are out of school with rashes not confirmed to be chicken pox.

School officials informed staff and parents of the students in each affected classroom of the exposure to chicken pox. There are a total of 669 students in the school.

Officials are urging parents to get their children immunized.  For more information on chicken pox and immunizations in general, please call the HHSA Immunization Branch at 619-692-8661 or visit
