Emerging Tickborne Diseases

Tuesday, March 21, at 1:00 p.m. ET

American Dog Tick

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.

Join us for this session of Public Health Grand Rounds as experts discuss emerging tickborne diseases, treatment options, prevention strategies, and advances in diagnosing tickborne diseases.

Future Grand Rounds topics include the National Amyotrophic Lateral Sclerosis Registry, promoting hearing health across the lifespan, and new frontiers in workplace health.

Beyond the Data — Emerging Tickborne Diseases

Dr. Phoebe Thorpe and Dr. Bobbi Pritt discuss the problem of emerging tickborne diseases. Find out the types of ticks in your area and the types of diseases a tick bite can transmit. Learn the ABCs of how the prevent tick bites and what to do if a tick bites you. Tick bites can cause co-infections. Health care providers need to consider this when diagnosing and treating potential tickborne diseases. Learn about some of the treatment options and discover the important role Public Health plays in tickborne disease awareness.

Our sessions are open to the public:

A live webcast will be available on our website. The link will be live five minutes before the presentation. View our sessions on our archive page at your convenience. Sessions are archived 3 to 4 days after each presentation.

For CDC staff unable to attend in person:
The session will be available on our webcast or on IPTV. (Note: IPTV is NOT available on CITGO).

For non-CDC staff who want to attend in person:
Non-CDC staff must have prior security clearance. US citizens must submit a request to the Grand Rounds Team. A US state-issued photo ID (e.g., driver’s license, US passport) is required.

Non-US citizens must submit their requests 20 days prior to the session to the Grand Rounds Team, and additional information will be required.

For individuals requiring reasonable accommodations:
It is the policy of CDC to provide reasonable accommodations (RA) for qualified individuals with disabilities to ensure their full inclusion in CDC-sponsored events. Employees are asked to submit RA requests at least 5 business days prior to the event. Please e-mail the request to

For questions about this Grand Rounds topic: Feel free to e-mail your questions before or during the session.

Grand Rounds is available for continuing education.
All continuing education credit for Public Health Grand Rounds (PHGR) is issued online through the CDC/ATSDR Training and Continuing Education Online system. If you have questions, you can email Learner Support or call them at 1-800-41-TRAIN (1-800-418-7246). Those who view PHGR and wish to receive continuing education must complete the online seminar evaluation. Continuing education will be available for up to 2 years and 1 month after the initial offering. The course code for all PHGR sessions is PHGR10.

Target audience: physicians, nurses, epidemiologists, pharmacists, veterinarians, certified health education specialists, laboratorians, and others.


  1. List key measures of burden of disease involving morbidity, mortality, and/or cost.
  2. Describe evidence-based preventive interventions and the status of their implementations.
  3. Identify one key prevention science research gap.
  4. Name one key indicator by which progress and meeting prevention goals is measured.

CE certificates can be printed from your computer immediately upon completion of your online evaluation. A cumulative transcript of all CDC/ATSDR CE credits obtained through the TCE Online system will be maintained for each user. We hope that this will assist CDC staff and other public health professionals in fulfilling the requirements for their professional licenses and certificates.
