More than 200 university students and employees in Los Angeles were given quarantine orders on Wednesday and Thursday, just days after a measles outbreak was declared in Los Angeles County.
U.C.L.A. and California State University, Los Angeles, have been working with county health officials to identify and contact students and employees who may have been exposed to measles this month.
Those at risk of having contracted measles were given health officer orders — legal orders issued by county officials — to stay home and avoid contact with other people as much as possible.
At California State-Los Angeles, quarantine orders were issued on Thursday in response to potential exposures to a contagious person who visited a university library on April 11.
“At this point, 127 staff employees and 71 student employees have been sent home under quarantine orders,” the university said in an emailed statement on Thursday evening.

At U.C.L.A., a student who had contracted measles attended classes in two university buildings on April 2, 4 and 9 while contagious, Chancellor Gene D. Block said in a statement on Wednesday.
“Upon learning of this incident, U.C.L.A. immediately identified and notified more than 500 students, faculty and staff with whom the student may have come into contact or who may have otherwise been exposed,” Dr. Block said.
He added that most of those people were cleared, but 119 students and eight faculty members did not have the necessary medical records immediately available, so county officials issued quarantine orders on Wednesday.
“We have arranged for those who live on campus to be cared for at U.C.L.A. while they are quarantined,” the statement added.
In another statement on Thursday, the university said it had cleared 43 more students and two faculty members, reducing the number of people under quarantine there to 82.
“We expect the trend to continue as more people provide proof of immunization or are shown by tests to have immunity to measles,” the university said.
Quarantine orders can last up to 21 days from the date of possible exposure. The quarantine period for U.C.L.A. ends on April 30, and the one for California State-Los Angeles, ends on May 2, the Los Angeles County Department of Public Health said Thursday.
The department believes additional measles exposures may have occurred this month at Los Angeles International Airport and at several restaurants near Glendale.
Measles is an extremely contagious virus that can cause serious respiratory symptoms, rash and fever. In some cases, especially in babies and young children, the consequences can be severe. Pneumonia and encephalitis — swelling of the brain — are the most common severe complications.
A single case of the measles can quickly spiral into an outbreak, especially because people might not know they have the illness for several weeks before they begin to show symptoms.
People who do contract measles often seek medical care at hospitals, where they can potentially transmit the illness to other patients, especially those with compromised immune systems. Infants typically do not receive measles vaccinations until they are about 1 year old and therefore are highly vulnerable. Some older people are also at high risk, as are patients who take medication that affects the immune system, like those being treated for arthritis.
Los Angeles is the latest metropolitan area to be hit by measles, as part of a national surge in cases. On Wednesday, federal health officials said that the number of measles cases in the United States had risen to 695, the highest annual number recorded since the disease was declared “eliminated” in the country in 2000.
The virus mostly has affected families that do not vaccinate their children, and the Centers for Disease Control and Prevention has blamed “organizations that are deliberately targeting these communities with inaccurate and misleading information about vaccines.”
