AUSTIN, Texas (CBSFW.COM/AP) — At least 4,116 new confirmed coronavirus cases were reported Tuesday, an increase of 1,742 from Monday, the Texas Department of State Health Services said.

The state reported 59 fewer COVID-19 hospitalizations, however, with 4,144 reported for Tuesday.

The new cases brought the total for the six-month outbreak to at least 617,333, with an estimated 89,791 cases now active.

However, the true number of cases in Texas is likely higher because many people haven’t been tested and studies suggest people can be infected and not feel sick.

The 145 deaths reported Tuesday brought the Texas death toll for the outbreak to 12,681.

Meantime, the rolling seven-day average rate of positive test results for the virus tat that causes COVID-19 fell dramatically to 10.13% as of Monday, the most recent day available.

The Sunday average was 11.96%, a sharp drop from 24.5% reported Aug. 11. The seven-day average of tests administered was 46,600 as of Monday, an increase from 40,300 as of Sunday but still down from 49,500 as of Aug. 21 and sharply down from 63,900 as of Aug. 18, the Department of State Health Services reported.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks.

For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and be fatal.
