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 […]
Other Tick-Borne Diseases
One tick bite can give people more than one tick-borne disease (co-infection). In addition to Lyme disease, here are some other tick-borne diseases found in the US.
Pfizer has received priority review for their vaccine, TicoVac, that protects against tick-borne encephalitis. This tick-borne virus can cause meningitis and trigger long-term neurological symptoms. If approved, the vaccine would potentially protect travelers as well as members of the US military that are deployed to regions where the virus is common, such as Europe and parts of Asia.
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, […]
Tularemia is caused by a bacterium, Francisella tularensis, transmitted by ticks. It can also be transmitted by deer fly bite, contact with infected animal, contaminated water, contaminated aerosols or agricultural dust, bioterrorism. Symptoms can include headache, chilliness, vomiting, aching pains, fever, swollen glands, sweating, weight loss, debility, infection site developing into an ulcer. Treatment can […]
The results of a study to collect ticks from Pike County, Pennsylvania, conducted by the Northeast Wildlife DNA Laboratory of East Stroudsburg University included real time PCR analysis of ticks countywide. The county was divided into 9 grids, each with several collection sites. The sites were based on use by community members and presence of […]
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.
Severe Fever with Thrombocytopenia Syndrome (SFTS) cases first appeared in April 2020 in China and since then, 37 more cases have occurred in Jiangsu and 23 in Anhui Provinces in China. SFTS is a haemorrhagic fever transmitted by the Haemaphysalis longicornis tick (Asian longhorned tick). The disease spreads rapidly and has a high fatality rate […]
The picture in New Jersey of spotted fever group rickettsiosis (SFGR), which includes Rocky Mountain Spotted fever (RMSF), is complex. In this latest study from the Am. Journal of Tropical Medicine and Hygiene (James Occi, Rutgers University, et al, ), the researchers tested American dog ticks and lone star ticks in NJ to determine which […]
Alpha-gal is a sugar molecule found in most mammals (not people, apes, monkeys) and in products made from mammals including medications, vaccines, cosmetics, gelatin and milk products. It is not normally found in fish, reptiles or birds. Alpha gal is also found in some types of ticks. Click here for CDC website on Alpha-gal What […]
