New study summarizes human surveillance data from 2011-2018 in the United States for Babesia infections reported to the Centers for Disease Control and Prevention (CDC) through the National Notifiable Diseases Surveillance System (NNDSS). Data shows an increasing trend of reported Babesia cases (14,159 total) during this time period, with white men in the middle and […]
In this newly published review, authors address the geographic distribution of the human-infecting Babesia spp., their phylogenetic relationship, and their tick vector worldwide. Authors found that the number of human Babesiosis cases appearing in the literature has increased exponentially in the last 10 years, with the US leading the world in reported case numbers.
A study by Mikhail et al in Open Forum Infectious Diseases, Feb. 2021, from 2006 to 2017 showed 19,469 beneficiaries had babesiosis recorded, a substantial increase. The highest states by rates were Massachusetts (62), Rhode Island (61), Connecticut (51), New York (30), and New Jersey (19). States previously considered nonendemic saw increases: New Hampshire, Maine, […]
In a recent study conducted in central Pennsylvania, evidence of emerging pathogens, some also common to ticks, have been found in fleas. Various pathogens can be spread by ectoparasites among animal host populations in nature. Along with ticks, fleas are found to commonly infest small mammals. The role of pathogen transmission cycles for these vectors is unknown. Only the white footed mouse tested positive for the blood‐borne pathogens examined, with 47 (18.1%) positive for Anaplasma phagocytophilum and ten (4.8%) positive for Babesia microti. Other pathogens included Bartonella vinsonii, B. microti, and a Rickettsia felis‐like bacterium.
Babesiosis is a Malaria-like illness caused by a parasite, either Babesia microti, B. duncani, B. divergens, MO-1. It is sometimes fatal in the elderly or those with no spleen. Babesiosis may be more severe in patients with co-existing Lyme disease. Symptoms include: fever, chills, fatigue, headache, muscle pain, sweats and anemia. Tests for Babesiosis: blood smears, IFA (IgG […]
