About COVID-19 Graphs

Understanding Epi Curve of Cases Over Time

The Epi Curve of Cases Over Time graph shows the number of lab-confirmed cases recorded each day. Cases are based on positive Coronavirus tests within Harris County. These confirmed test results are provided by the State of Texas, Hospitals, and Commercial Labs.

The graph shows COVID-19 cases with the date of each case assigned based on information collected by epidemiologists when they investigate a lab-confirmed positive case. This date is based on multiple criteria which goes in order of...

  1. Date of symptom onset:  The date symptoms began, as reported by the individual.  This date may fall before date of diagnosis.
  2. Date of specimen collection: The date of collection of the first lab-confirmed positive specimen.
  3. Date of laboratory result: The date of the first laboratory confirmed positive test result.
  4. Date of first report to the public health system: The date the case was first reported to the local health department.

*It is important to note that a high volume of cases reported for these dates does not mean that all cases are currently Active.

Filter Cases By Epi Curve

When a date (or multiple dates) is selected within the Epi Curve of Cases Over Time graph, the other elements in this dashboard will adjust to show only those cases with an epi date matching what is selected. These elements include:

  • Confirmed Cases
  • Active Cases
  • Recovered Cases
  • Death
  • Sex Impacted
  • Age Groups Impacted

View Specific Timeframes

To view specific timeframes in this graph, simply use the slider at the top of the graph to change the start and end date of data shown. Multiple dates can also be selected one-by-one or by clicking and dragging your cursor over the desired bars in the graph.

About Reported Cases Graphs

About Reported Cases Graphs

The Reported Cases graphs show a timeline in which cases are reported to the local health department. Cases are divided into two types:

  • Recent Cases - Those cases that are reported and confirmed within 14 days of the specimen collection date or the date of laboratory result.
  • Older Cases* - Those cases that are reported and confirmed more than 14 days after the specimen collection date or the date of laboratory result. 

These graphs include All (Harris County including City of Houston), Harris (Harris County excluding City of Houston, and COH (City of Houston only). 

*It is important to note that not all the cases reported as Older Cases are still considered as Active.


Filter Reported Cases

Unlike the Epi Curve of Cases Over Time graph, the Reported Cases graphs will not filter based on region, demographics, or zip code as described in previous sections.


View Specific Timeframes

To view specific timeframes, simply use the slider at the top of the graph to change the start and end date of data shown.
