WHAT YOU NEED TO KNOW ABOUT COVID-19

FAQ's About COVID-19 

Is Texas tracking variants of COVID-19?

Yes. Public health officials at the federal, state, and local levels continue to study variants, monitor their spread, develop strategies to slow their spread, and test how variants may respond to existing therapies, vaccines, and testing. For information on variants of concern in Texas, see the Variants and Genomic Surveillance for SARS-CoV-2 in Texas section of the DSHS website.

Who is at most risk or contracting a variant of COVID-19?

Unvaccinated people are most at risk of contracting COVID-19, including any of its variants. 

The absolute best protection for yourself and those close to you is getting fully vaccinated. The vaccine is proven to safely protect you from COVID-19’s worst effects and lowers your chances of spreading the virus. Greatly increasing the number of fully vaccinated Texans is the only way to prevent a devastating rise in the spread of the pandemic virus.


What's the treatment for patients COVID-19?

There are different treatment options available for all COVID-19 variants, but some treatments may be more effective for certain variants. If you or a loved one is sick, check with your healthcare provider about your specific case.

What is the current travel guidance?

Stay up to date with CDC travel recommendations by visiting the Travel page of the CDC website.

Are people of certain ages at higher risk for infection with the newer variants?

Yes. Anyone who is not fully vaccinated is at greater risk of getting COVID-19.  Anyone who is old enough and able to get the vaccine should do so to protect those who are unable to get it, as well as those for whom the vaccine is less protective. It's also important for those people who qualify to get the booster dose, too.

How many variants are there?

There are many. Because viruses constantly change through mutation, new variants occur all the time. Sometimes they disappear, and sometimes they persist. Variants are classified in four ways, from least to most severe: Variants Being Monitored, Variants of Interest, Variants of Concern, and Variants of High Consequence.

To learn more about variants in the U.S., visit the About Variants of the Virus, Variant Classification, and Variant Surveillance pages on the CDC website.

What are the differences between the variants?

Variants vary by their genetic markers. These differences in genetic markers may affect how easily the virus is spread, the severity of illness, how well existing tests can detect the virus, the effectiveness of treatments and vaccines, and more.

Each variant is slightly different. Think of variants like branches on a tree. Each branch is slightly different than others on the tree, but they have similarities, too. Scientists study the differences in COVID-19 variants, so they can label and track them according to those differences.

Do the vaccines protect against the variants?

The best protection against any COVID‑19 variant is getting fully vaccinated. And a booster dose of vaccine is a proven way to maximize the protection against infection and severe disease.
