New data reported by the Harris County Public Health Department from the end of December shows the 14-day average for coronavirus testing positivity trending toward 20% after several days of steep increases.
The 14-day average—which steadily rose from 13.1% on Dec. 18 to 15% on Dec. 28—had jumped to 16.5% by Dec. 31, according to county data. The upward swing took place after six straight days of testing positivity coming in at more than 19%, a trend that has not been seen in Harris County since July.
Due to a data lag, testing positivity rates for individual days are dynamic and may be adjusted as additional test results are recorded. The 14-day average has been on the rise in Harris County since hitting a low point of just over 5% in early October. By the start of December, the 14-day average had reached 9.4% in the county.
Another 2,758 new cases of COVID-19 were confirmed in Harris County on Jan. 7, including 1,586 new cases in the city of Houston and 1,172 in Harris County outside of the city. Meanwhile, the number of confirmed COVID-19 deaths in the county increased by 13, hitting 2,680 since the pandemic began.
