The San Diego County Health and Human Services Agency (HHSA) reports that seven students at Challenger Middle School in Mira Mesa have been diagnosed with chicken pox. Also, three children at Santee KinderCare Learning Center have been diagnosed with chicken pox.
Five of the middle school students had one dose of vaccine; two had no vaccine. Two of the childcare children had one dose of vaccine; one had no vaccine. Two doses of vaccine are recommended to guard against contracting chicken pox, or lessen its effects.
“We urge parents to talk to their children’s healthcare provider about ensuring that children have had age-appropriate vaccinations against diseases like chicken pox,” said Wilma Wooten, M.D., M.P.H., County Public Health Officer. “When children are not protected, it’s easy for disease to spread when they get together at school, childcare centers, and other venues.”
None of the students required hospitalization. School and childcare center officials have informed staff and parents of students who may have been exposed, and recommended that children have the appropriate vaccinations against the disease.
Chicken pox is a highly contagious disease caused by the varicella virus. The disease is easily spread by coughing, sneezing or contact with chicken pox blisters. The Centers for Disease Control and Prevention recommends two doses of chicken pox vaccine for those who do not have immunity -- the first at 12-15 months of age and the second at 4-6 years of age. A second dose is recommended for individuals who are older and have only had one vaccination,
Symptoms of chicken pox include a skin rash of blister-like lesions, covering the body but usually more concentrated on the face, scalp, and trunk. The risk of complications increases after puberty and includes bacterial infection of skin lesions, dehydration and pneumonia.
Most, but not all, infected individuals have fever, which develops just before or when the rash appears. If exposed, persons who have been vaccinated against the disease may get a milder illness, with less severe rash (sometimes involving only a few red bumps that look similar to insect bites) and mild or no fever. The incubation period is 10-21 days. The illness lasts about 5-10 days.
