Disease information

Disease surveillance is at the heart of a public health system. It is used to monitor disease trends over time, to detect disease outbreaks, and to increase our knowledge of risk factors that contribute to disease development.

Under Texas law, health care providers, hospitals, laboratories, schools, and others are required to report cases of nearly 80 different diseases and health conditions to local and state health officials.

General Reporting form with Texas Reporting Form

The Garland Health Department Communicable Disease Surveillance program receives case reports and collects additional detailed information through case investigation. These reports help public health professionals understand the incidence of diseases in the community, and guide appropriate prevention strategies or protective measures to reduce the spread of disease in the community.

COVID-19 Information

Self-Testing at Home

A self-test produces fast results and can be taken anywhere. You can use self-tests if you have COVID-19 symptoms or have been exposed to someone sick with COVID-19, or even if you don’t have symptoms. Call your local pharmacy to ask about whether they have self-tests available.

Learn more about Self-Testing (CDC). Visit FDA’s website for a list of authorized tests. Some self-tests may have age limitations.

If you take a self-test and get a positive result, tell the people you might have seen recently and find recommendations for quarantine and isolation (CDC). Call your healthcare provider if you have questions or concerns about symptoms, or if you are at higher risk for developing severe illness.  You can report positive self-tests to Garland Public Health online. 

For updates about COVID-19 vaccine availability and administration, visit the COVID-19 Vaccine Information page. Are you experiencing potential COVID-19 symptoms? The CDC offers resources and guidance for what to do if you're sick, as well as updated quarantine and isolation guidelines.

Additional testing information is available on the COVID-19 Facts & Resources page.
