What is Influenza?

Influenza ("the flu") is:

  • A contagious respiratory illness caused by a virus
  • Spread through coughing, sneezing, and touching items that are contaminated with the virus (e.g., doorknobs, keyboards, etc.)

Individuals with the flu are infectious 1 - 2 days before showing symptoms and during their entire illness.

Is it the Flu?

Symptoms of the Flu:

Seasonal vs. Pan Flu

Seasonal Flu
The seasonal flu presents each year, giving most people some immunity from previous exposure. Health systems can usually meet public needs.

Pandemic Flu
A rarely occurring phenomenon, pandemic flu arrives with little, if any previous exposure to human populations. Health systems may be overwhelmed.

Seasonal Flu Vaccination

An effective prevention measure against influenza is vaccination.

The Flu Shot Locator provides a searchable map showing where clinics can be found anywhere in Indiana.

Contacting your Local Health Department will also provide locations in your community where vaccination clinics can be found.
