CHULA VISTA, Calif. (KGTV) -- A South Bay woman and her child are under self-quarantine due to possible exposure to the coronavirus.

In a letter sent to Feaster Charter School staff and parents on Thursday, the Chula Vista Elementary School District confirmed that the parent of a preschool student may have been exposed to COVID-19 due to contact with a person who was recently diagnosed with the virus.

10News learned the parent’s possible exposure is connected to the case of an AT&T retail store manager who works at the Chula Vista Center location. The manager was initially diagnosed with coronavirus this week, but the Centers for Disease Control and Prevention has not fully confirmed the test result.

Meanwhile, the manager -- who does not live in San Diego County -- is under self-quarantine, and her case is being handled by Orange County health officials.

The parent is one of several San Diego County AT&T store employees who had contact with the affected manager, leading her to self-quarantine herself and her child. The other workers have also self-quarantined.

District officials said they do not believe Feaster Charter students and staff were exposed to the virus.

Prior to the letter being sent, the school had already been taking necessary precautions.
