This course teaches how to diagnose and treat infections caused by babesia, a malaria-like protozoan parasite that can be transmitted through tick bites, blood transfusions, and organ transplants, or congenitally from mother to fetus. The course also discusses the global distribution of babesia and a new species of babesia, B. odocoilei, which may be causing unrecognized disease.
This session, An Introduction to Human Babesiosis, is approved for 0.25 enduring AAFP Prescribed credits.
AAFP Prescribed credit is accepted by the American Medical Association as equivalent to AMA PRA Category 1 credit(s)™ toward the AMA Physician’s Recognition Award. When applying for the AMA PRA, Prescribed credit earned must be reported as Prescribed, not as Category 1.
The AAFP has reviewed One Health Medical Education for a Changing Climate, and deemed it acceptable for AAFP credit. Term of approval is from 01/02/2023 to 01/01/2024. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
- Describe the epidemiology of Babesiosis in the US
- Identify the signs and symptoms of Babesiosis
- Discuss the types and limitations of diagnostic testing
- Discuss treatment approaches for Babesiosis
