A student at Arizona State University has started a petition to cancel classes after someone from the university was confirmed to be infected with the coronavirus.

ASU freshman Taskina Bhuiyan, who is majoring in microbiology, started the petition on Change.org, and it had more than 21,000 signatures as of Wednesday evening.

It is unclear whether the infected person is a student or staff member. The Arizona Department of Health Services (ADHS) identified the person only as a "member of the Arizona State University community who does not live in university housing."

The person recently returned from Wuhan, China, where the virus is believed to have originated.

"As part of our case investigation, individuals who may have been exposed to the patient will be notified by public health and provided with proper follow-up," ADHS communications director Chris Minnick told CNN.

The ADHS said the patient is not severely ill. The patient is being kept in isolation to prevent the illness from spreading, according to the health department.
