LOS ANGELES (KABC) -- Hundreds of students and staffers at two Los Angeles universities were quarantined or ordered to stay home Friday, skyrocketing since officials announced two cases of students who may have exposed the campuses to the highly contagious illness.
Department of Public Health officials said at California State University Los Angeles, 183 people are still under individual quarantine orders, and 445 people are under a blanket quarantine order as of Friday. Plus, an unknown number of people are under a blanket quarantine order and are being asked to self-report if they were at Cal State L.A.'s Library North on April 11 from 11 a.m. to 3 p.m.
Those under the orders have been told to stay home and avoid contact with others as much as possible.

Los Angeles County health officials said 129 UCLA students were quarantined on campus or self-isolating off campus as of Friday. That number is slightly higher than the initial 117 held Thursday. The student with measles attended classes at Franz Hall and Boelter Hall on April 2, 4 and 9 while contagious, according to UCLA.
"We expect that those notified will be quarantined for approximately 24-48 hours until their proof of immunity is established. A few may need to remain in quarantine for up to seven days. We have arranged for those who live on campus to be cared for at UCLA while they are quarantined," UCLA said in a statement.
Several other cases have been reported across the L.A. area.

Measles is highly contagious and can stay in the air for up to two hours after an ill person coughs or sneezes, and can stay on surfaces for several hours, health officials say. About 90 percent of people who are exposed and not immune to the illness become sick 7 to 21 days after exposure.
Measles symptoms include fever, dry cough, runny nose, sore throat and red, watery eyes. Three to five days after symptoms begin, the CDC says a rash breaks out which appears as flat red spots on the face at the hairline and spread downward to the neck, trunk, arms, legs and feet. Small raised bumps may also appear on top of the flat red spots.
