AUSTIN (KXAN) — KXAN is keeping track of COVID-19, the disease caused by the coronavirus, by aggregating data from the Texas Department of State Health Services and local and county health departments. Click here for data specific to Central Texas.
How prevalent is COVID in my county?
In February 2022, the CDC began weekly updates determining the “COVID Community Level” in each county nationwide. The three levels — High, Medium and Low — show how prevalent COVID-19 is in each county, by looking at hospitalization and case data. The data is updated weekly.
Where have cases been reported?
The state’s first case of COVID-19 was reported March 4, 2020, in Fort Bend County. Texas reports totals for two kinds of cases: confirmed and probable. A confirmed case is a person who has tested positive on a molecular test. A probable case is a person who has tested positive on an antigen test, or someone who has a combination of symptoms and known exposure to someone with COVID-19.
Harris County has the most confirmed cases of COVID-19. When adjusted for population though, other counties rise to the top, most notably Loving, Dimmit and Jim Hogg Counties. The map above shows the rate of cases per 1,000 people, using 2020 population totals from the U.S. Census Bureau.
Where have deaths been reported?
Texas identifies COVID-19 deaths using the cause of death listed on death certificates. The total number of deaths does not include people who had COVID-19 but died from an unrelated cause. The state’s first COVID-19-related death was reported March 16, 2020, in Matagorda County.
How many people have been vaccinated?
The first vaccines in Texas were administered on December 14, 2020. The map below shows the percentage of Texans in each county that are fully vaccinated against COVID-19.
KXAN is also keeping track of vaccination rates in each zip code across Texas. Click here to explore the data using our interactive map.
Both the Pfizer and Moderna vaccines require two doses for a person to be fully vaccinated. People who have taken one dose are considered partially vaccinated. The Johnson & Johnson vaccine only requires one dose, so people who take that vaccine are automatically considered fully vaccinated.
How has the number of cases changed over time?
KXAN is keeping track of the daily increase in COVID-19 cases and deaths across Texas. The highest daily jump occurred on Jan. 12, 2022, when 75,817 new cases (confirmed and probable) were added to the statewide total. The highest single-day increase in confirmed cases was 61,113 on Jan. 12, 2022. The highest single-day increase in probable cases was 15,223 on Jan. 13, 2022.
The largest increase in deaths in a single day occurred on Jan. 28, 2021, when 471 new deaths were reported.
How many people are in the hospital?
DSHS reports hospitalization data a day late. Texas hit a peak of 14,218 COVID-19 hospitalizations on January 11, 2021. The chart below shows how the number of people hospitalized because of COVID-19 has changed throughout the pandemic.

How many people have been tested?
The State of Texas is reporting numbers for three different types of tests:
- Molecular: These are used to determine whether someone is currently infected with COVID-19. If you test positive in a molecular test, you are counted as a “confirmed” case.
- Antigen: This test is a nasal swab that also determines whether someone is currently infected. They are sometimes referred to as rapid tests, because the results can come back in as little as 15 minutes. If you test positive in an antigen test, you are considered a “probable” case but not a “confirmed” case.
- Antibody: This type of test determines whether someone was previously infected. It’s a blood test that looks for proteins that the body creates to fight an infection. If you test positive in an antibody test, you are not considered a “confirmed” or “probable” case.
DSHS reports what it calls the “Specimen Collection Date Positivity Rate.” This measures the percent of tests that are positive. The state calculates the rates based on when tests are performed, not when the results are reported. Because of this, the rates fluctuate as DSHS retroactively updates new data it receives.
Which demographics are most affected?
The following charts show how the number of COVID-19 cases and deaths by age, sex and race/ethnicity. Updated data is reported by DSHS once a month.
