Fifteen new cases of measles have been reported in the Upstate since Tuesday, more schools have had infected students, 303 people are in quarantine and 13 in isolation, the South Carolina Department of Public Health reported Friday. The total number of cases in South Carolina related to the Upstate outbreak is 126 and 129 this year. Quarantine involves staying home 21 days after a known exposure to monitor symptom development. Students who are not immunized and were exposed to a known case are not allowed to attend school. Isolation is indicated when an individual has the measles and is infectious, which is four days after the rash appears. Six of the 11 schools affected reported immunization levels in the low 80s. The Department of Health said 95% offers herd immunity. Statewide, the immunization level has dropped to 90%. Two of the schools with quarantines — Dorman Freshman Campus and Fairforest Middle— have 94% and 90% immunization levels respectively. Chapman, Hendrix and Tyger River reported high 80s.

| Symptoms: | The classic signs and symptoms of measles include four-day fevers [ the 4 D's ] and the three Cs—cough, coryza (head cold), and conjunctivitis (red eyes)—along with fever and rashes. The fever may reach up to 40 °C (104 °F). Koplik's spots seen inside the mouth are pathognomonic (diagnostic) for measles, but are not often seen, even in confirmed cases of measles, because they are transient and may disappear within a day of arising. Their recognition, before the affected person reaches maximum infectivity can be used to reduce spread of epidemics. The characteristic measles rash is classically described as a generalized, maculopapular, erythematous rash that begins several days after the fever starts. It starts on the back of the ears and, after a few hours, spreads to the head and neck before spreading to cover most of the body, often causing itching. The measles rash appears two to four days after the initial symptoms and lasts for up to eight days. The rash is said to "stain", changing color from red to dark brown, before disappearing. |
