COVID-19 Case Counts and Testing Figures

While COVID-19 is a disease that can cause serious illness and death, and those 65 and older or those with underlying health conditions are most vulnerable, studies by the World Health Organization estimate that approximately 80% of persons with COVID-19 have a mild illness that resolves. The remaining persons with COVID-19 have more severe illness that may lead to hospitalization, delayed recovery and occasionally death. It is important to follow the state and local health official orders and guidance, which will help to protect all of us, especially the most vulnerable in our community.

* While every case of the new coronavirus that causes COVID-19 is reported to HCA, there is no practical way to find out if they’ve recovered. Moreover, many people may have experienced some symptoms of COVID-19, but were not tested, making it impossible to know the exact number of COVID-19 infections and recoveries. However, because it is important to know approximately how many residents may have been exposed and recovered in Orange County, an attempt to estimate the number of recovered cases by taking the difference between the prior 28-day cumulative case count and current day mortality to determine the current day recovered total. Please note that these data are only an estimate and should be interpreted with caution. [Methodology: Prior 28-day cumulative case count – current day mortality = current day recovered]

 

Numbers fluctuate day-by-day due to changes in patient condition(s). Data are gathered daily at one point in time.

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.

4 To provide more inclusive reporting and case distribution throughout Orange County, effective April 2, 2020, positive COVID-19 cases by city will include incorporated cities and unincorporated areas of the county.
