Coronavirus cases in Orange County jumped past 400 this week, county health officials said. Four people have died.

As of Sunday, the county had performed more than 5,100 tests.

Age breakdown of cases:

0-17 — 2

18-44 — 188

45-64 — 162

65+ — 77

Unknown — 2

Officials on Friday began releasing city-by-city coronavirus cases, with Huntington Beach, Newport Beach, Irvine and Anaheim having among the highest totals.

"While no one wants to see cases, Anaheim’s count isn’t surprising or alarming," city spokesman Mike Lyster said Sunday. "We guided our city to expect about 10% of Orange County’s cases, in line with Anaheim’s share of the county’s population."

"Like all of Orange County, we will see growth in cases as more people are tested." he added. "The upside of that is those are likely to be cases that already exist in our city, and those patients will be treated and isolated until they recover."

County officials also have urged residents to avoid drawing broad conclusions from the city-by city figures.

“COVID-19 now has reached community transmission status, which means people may have contracted the illness elsewhere in the county. This may not necessarily be in the city where they live,” the county said in a statement. “These data should not be interpreted as an indication of activity in any specific location. Under a community transmission status, the true prevalence of this disease may not be known, as most cases are likely not diagnosed or reported.”
