Webinar Details

This CDC Public Health Grand Rounds webinar gives an overview of tick-borne diseases in the United States of America.

Tick bites can transmit bacteria, viruses, or parasites.  Ticks can carry more than one infectious agent at a time.  Recently, new tick-borne diseases have been discovered in North America, and the number of human infections from known diseases has been rising.  Co-infections add to the difficulty of diagnosis and treatment.

The webinar covers relevant tick ecology:  geographic ranges and frequency, cold and heat tolerance, and which diseases each tick species carries.

Infections from tickborne diseases in the US are steadily increasing — and new tickborne diseases have been discovered in recent years. Ticks are vectors that can carry infectious agents such as bacteria, viruses, or parasites. When an infected tick bites a person or an animal, the tick’s saliva transmits infectious agents that can cause illness. Some ticks can transmit multiple diseases. These “co-infections” pose challenges for diagnosing, treating and preventing tickborne diseases.

The geographic ranges of ticks also are expanding. Ticks differ in their tolerance to heat, cold and aridity, making certain tick species more common than others in any given location in the United States. Different species transmit different diseases and this leads to differences in incidence of tickborne diseases by geographic region in the US.

The webinar gives an overview of:

  • emerging tickborne diseases,
  • treatment options,
  • prevention strategies,
  • advances in diagnosing tickborne diseases.
