Total Cases

Because the Delaware General Health District strives to provide the most accurate, transparent data possible to the public, we are adjusting our reporting to every Monday, Wednesday and Friday. This new schedule gives our epidemiologists time to conduct quality assurance with our data to make sure it is the most accurate prior to release.  


Portions of Delaware County are annexed to Columbus Public Health and Franklin County Public Health based on tax jurisdiction, including Dublin, Washington Township, Columbus and Westerville. If a resident would test positive for COVID-19 in one of those jurisdictions, then the public health department in Columbus or Franklin County would handle that case, even if they reside in Delaware County.


The Ohio Department of Health is requiring both lab-confirmed and probable cases of COVID-19 be reported within 24 hours to the local health department in the jurisdiction in which the case resides. We will report out both the number of positive lab-tested cases and the number of probable cases of COVID-19. A probable case must meet a specific CDC definition and is determined by a healthcare provider and/or the Delaware General Health District. A healthcare provider and/or the Delaware General Health District must determine if the symptoms along with other diagnostic tools indicate the ill person falls within the CDC definition for a probable case.

The Health District aims to provide real-time data to the public, but a drawback to real-time data is that during disease investigations numbers can change for a variety of reasons. Some of these reasons may include jurisdiction or a probable case becoming a non-case after testing negative. When we receive negative lab results, we reclassify them to “not a case” and subtract them from any other category they were also in, like “recovered.”

Delaware General Health District, in coordination with the Ohio Department of Health (ODH), and the Centers for Disease Control and Prevention (CDC), is closely monitoring coronavirus disease 2019 (COVID-19), first identified in Wuhan, Hubei Province, China.


CDC is responding to an outbreak of respiratory disease caused by a novel (new) coronavirus that was first detected in China and which has now been detected in 60 locations internationally, including in the United States. The virus has been named “SARS-CoV-2” and the disease it causes has been named “coronavirus disease 2019” (abbreviated “COVID-19”).

On January 30, 2020, the International Health Regulations Emergency Committee of the World Health Organization declared the outbreak a “public health emergency of international concernexternal icon” (PHEIC). On January 31, 2020, Health and Human Services Secretary Alex M. Azar II declared a public health emergency (PHE) for the United States to aid the nation’s healthcare community in responding to COVID-19.
