Williamson County reported 548 new cases of COVID-19 on Jan. 5, its second-highest single-day case count since the start of the pandemic, according to a Williamson County and Cities Health District report.

The total number of confirmed cases is 22,436.

Due to the increase in cases, the WCCHD has asked that anyone who gathered or traveled during the holidays stay home for seven days, even if they receive a negative test for the coronavirus. Anyone who tests positive should isolate for 10 days to protect others from getting infected, it said.

The county also reported a spike in hospitalizations of patients with COVID-19, with 153 patients. The day before, the county reported 133 hospitalizations, data shows.

There are 57 patients in intensive care units and 31 on ventilators in the county. The WCCHD also reported 12% of hospital beds, 7% of ICU beds and 57% of ventilators are available.

The death toll is 214.

Counted deaths are of those who have COVID-19 listed as a direct cause of death on the death certificate. The total does not include deaths of people who had COVID-19 but died of an unrelated cause, according to the Texas Department of State Health Services dashboard. This method may delay reporting by weeks or even months due to paperwork, county health officials have said.

Williamson County continues to sit at the red level for coronavirus transmission risk. This is characterized by uncontrolled community spread, according to the WCCHD.

Of the total cases reported, 20,321 are estimated to have recovered, and there are an estimated 1,901 active cases. There are 2,797 total probable cases.

The current rolling seven-day positivity rate, or the rate at which tests for the coronavirus return positive, sits at 16.56%.

Recoveries are not reported to the state’s contact tracing and data system; therefore, recovery information is not absolute and is to be used for estimating purposes only, according to the WCCHD website. No trends or other inferences should be drawn from this data, as the numbers posted represent a point-in-time snapshot and may fluctuate throughout the day, it said.

Total cases by cities of residence, including probable cases, according to the WCCHD, are as follows.

  • Austin: 1,670

  • Cedar Park: 2,236

  • Georgetown: 4,652

  • Hutto: 1,600

  • Leander: 1,689

  • Round Rock: 6,132

  • Other: 3,032

If the WCCHD is unable to confirm the city of residence after three attempts, the case is deemed “lost to follow-up” and is not included in the above count, officials said.

Here is a breakdown of deaths by city, according to the WCCHD.

  • Cedar Park: 32

  • Georgetown: 44

  • Not specified: 14

  • Other: 36

  • Round Rock: 88

Officials said the county is not legally able to release the specific counts in cities with fewer than 20,000 residents. For more information, such as gender and age breakdowns, visit the county's dashboard.
