Influenza, known as "the flu," is a contagious respiratory illness caused by a virus. Most people will have mild illness, but some cases can result in hospitalization or even death.


The Centers for Disease Control and Prevention recommends that anyone six months of age and older should be vaccinated for the flu every flu season. High-risk individuals include:

  • Adults over 65
  • Pregnant women
  • People with chronic medical conditions
  • Health care workers
  • Individuals who live with and/or care for high-risk individuals

Flu shots are available at Shots for Tots/Big Shots clinics for uninsured children and adults. The shot costs $25 for adults, $10 for children, and free for children with Medicaid. For an appointment, call 512-972-5520.

For those who are insured, visit to find a location with flu shots near you.


In addition to the flu vaccine, there are preventative measures people can take to prevent the flu:

  • Wash your hands often with soap and water, or use an alcohol-based hand sanitizer if soap is unavailable
  • Cough and sneeze into your sleeve or tissue
  • Avoid touching your nose, mouth, and eyes
  • Avoid others who are sick
  • Stay home if you are sick


You many be contagious from one day before and up to seven days after becoming sick. Influenza may present the following symptoms:

  • Sudden onset
  • Fever or chills
  • Cough, sore throat
  • Runny or congested nose
  • Body aches
  • Headache
  • Severe fatigue

If you contact your doctor within 48 hours of symptom onset, you may be able to take an antiviral drug, which will reduce the severity of symptoms and length of the illness.

Seek immediate medical attention if a child has trouble breathing, has bluish skin color, is not waking up or interacting. Seek immediate medical attention if an adult has difficulty breathing, shortness of breath, sudden dizziness or confusion, is severely or persistently vomiting, or improves but then gets worse.

Percentage of Visits Due to Influenza-like Illness Reported by Travis County Participants in ILINet: 2016-2020

Austin/Travis County influenza surveillance does not capture all cases of influenza or influenza-like illness. The reporting of seasonal influenza is voluntary. This data should be used for trending purposes over time and for identifying types/strains of influenza that are occurring in the Austin area rather than for estimating the total number of cases.
