CDC Grand Rounds (Today): Emerging Tickborne Diseases


















#12,334



Each month the CDC holds a Grand Rounds web presentation that focuses on a single health-related issue.  In the past I’ve highlighted their broadcasts on such diverse topics as Multidrug-Resistant Gonorrhea, Childhood Emergency Preparedness, and Discovering New Diseases  . . . to name a few.

The CDC maintains an archive of these informative presentations – going back to 2009 – which you can access at Grand Rounds – ArchivesHighly recommended.

With the arrival of spring also comes an inevitable increase in vector borne diseases.  And while mosquito-borne diseases like Zika, Dengue, and Yellow Fever tend to garner the most headlines - in terms of their impact on the health of Americans - tickborne diseases inflict a far greater toll (see CDC: Estimate Of Yearly Lyme Disease Diagnoses In The United States).
While Lyme disease is best known by the public, the The CDC lists a growing number of diseases carried by ticks in the United States, including: Anaplasmosis, Babesiosis , Ehrlichiosis, Heartland Virus, Powassan Disease, Rickettsia parkeri Rickettsiosis, Rocky Mountain Spotted Fever (RMSF), STARI (Southern Tick-Associated Rash Illness), Tickborne relapsing fever (TBRF), Tularemia, and 364D Rickettsiosis . . . 

Complicating both diagnosis and treatment, many ticks carry more than one disease.


The details of today's presentation follows.  The presentation may be viewed live on their website, or the archived version will be posted in 3 to 4 days here.




Emerging Tickborne Diseases

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

he 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.
