Four months of Katy-area data shows that the total number of confirmed cases has increased at a faster rate between June 20 and July 20 than previous time periods.

As of April 20, when Katy’s three counties began providing local COVID-19 data, there were a total of 405 confirmed cases since the beginning of the pandemic across the seven Katy-area ZIP codes.

As of May 20, there were a total of 874 cumulative cases, which is an increase of 469 cases or a percentage change of 115.8%%.

As of June 20, the counties had reported a total of 1,741 cases since the beginning of the pandemic, an increase of 867, which equals a 99.2% change from the data reported May 20.

As of July 20, dashboard data from Harris, Fort Bend and Waller counties shows a total of 4,309 confirmed cases since the beginning of the pandemic. This is a 2,568 increase from June 20, or 147.5% month-over-month change.

Fort Bend County Health & Human Services said that this trend is a result of increasing interactions among residents.

“During May and June, as our community returned to pre-pandemic activities and made close contact with co-workers, family and friends, the virus had more opportunity to spread from person to person,” FBCHHS stated in a July 14 email.



Of the 4,309 confirmed coronavirus cases in the Katy area, about 87.6% of them are in Harris County, which is also providing information about cases that are active, recovered or died.

In ZIP codes 77493, 77449, 77084, 77094, 77450 and 77494, which are fully or partially within Harris County, there are a total of 2,110 recoveries and 18 deaths, leaving a total of 1,647 active cases.

ZIP code 77084 reports the highest number of active cases at 617, accounting for about 49.5% of its total cases.

ZIP code 77094, meanwhile, has the fewest active cases at 30, but those account for 55.6% of its total confirmed case count—the highest such share out of the six ZIP codes.

Fort Bend County has not reported any case changes in Katy-area ZIP codes that are fully or partially within the county—77494, 77450 and 77441—since July 17. It has noted previously that it does not update the ZIP code-level map on weekends.

The Fort Bend County dashboard shows a total of 524 confirmed coronavirus cases have been reported since the beginning of the pandemic in the Katy-area. It is not providing ZIP-level data for recoveries, deaths or active cases.

Waller County is providing partial data at the ZIP code level, and its July 19 update reported that all 10 of its Katy-area cases have recovered.
