From Jan. 1-Jan. 13, Williamson County saw 14,311 new cases of the coronavirus virus, according to data from the Texas Department of State Health Services.
These cases represent 16.7% of the total cases reported in the county since the pandemic began in March 2020 and an increase of more than 10,000 cases from the previous 14-day period from Dec. 18-31, which saw 3,032 cases.
Additionally, the 1,767 coronavirus cases reported Jan. 1 is the highest single-day case total ever recorded in Williamson County.
The number of new infections in Williamson County per 100,000 residents was 184.9 on Jan. 12, higher than the 98.3 cases per 100,000 residents seen in Travis County the same day, according to data from Williamson County and Cities Health District.
The new cases are driven in part by the omicron variant, which the Centers for Disease Control and Prevention says likely spreads more quickly than the original strain of the virus. The first case of the omicron variant was confirmed in Williamson County on Dec. 20.
