California health officials said patients were not quarantined before being tested and were walking around in their community.
Ms Newsom said 5 out of 33 patients who tested positive for the virus had left the state. Officials were not immediately clear whether the 33 positive cases were part of the Diamond Princess passenger group being evacuated from Japan to the United States.

In January, California received the first flight carrying people evacuated from Wuhan, China, the epicenter of the disease. All 195 passengers were isolated at an air force reserve base in Riverside County and were released earlier this month.
“More than 800 people return on those flights, but that is a small part of the overall picture. Thousands and thousands more return on more traditional flights across California,” Ms Newsom said.
A laboratory mistake earlier this month caused health officials to discharge a virus-infected patient from a quarantined group at the base of the US Marine Corps in San Diego, California. The CDC then said further tests showed that the patient had actually been tested positive for the virus.
