The number of measles cases in California continues to escalate, as the state health department confirms there are at least 91 cases reported, with 58 linked to the Disneyland outbreak first reported in mid-December.
Those statistics are likely to grow, however, as the numbers were last updated on Friday.
Orange County, Los Angeles and San Diego have the most reported cases: 27, 16, and 13 respectively.
In the Bay Area, Alameda County has the most cases (6), with 2 cases apiece listed in Marin, San Mateo and Santa Clara counties. One case was reported in Solano County on Friday, which hasn't yet been formally documented by the state.
The health department said there were at least 40 people who first got the highly infectious disease while they were visiting or working at Disneyland in Orange County and spread it to at least half a dozen other states.
The virus is also highly preventable through vaccines, something many parents choose not to do based on their personal beliefs. The issue has garnered much controversy, and even captured the attention of the president of the United States. Barack Obama told parents on the "Today Show" on Monday: "Get your kids vaccinated."
