Two students at an elementary school near Los Angeles may have leprosy, officials say.

The diagnosis hasn't been confirmed, but parents of students at Indian Hills elementary School in Jurupa Valley were alerted Friday about the possible cases of leprosy, United Press International reported.

Some parents kept their children home from school on Tuesday, while other students wore medical masks to school.

An official diagnosis will take weeks, according to Barbara Cole, director for disease control, Riverside County Department of Public Health, UPI reported.

Jurupa Unified School District Superintendent Elliott Duchon would not confirm if the two affected students were from the same household.

Leprosy, also called Hansen's disease, can be transferred between people living in close contact, but antibiotics will prevent transmission, according to the U.S. Centers for Disease Control and Prevention.
