Overall, the number of individuals contracting Babesia is rising. The annual number of cases per year climbed from 4 per 100,000 to 9 per 100,000 in the U.S. between 2006 and 2017. The annual number of cases of Babesia per year for individuals over the age of 85 was 4 out of 100,000. In comparison, […]

Powassan virus in children is not often reported. In this article, the authors describe powassan virus in children involving two infants with tick bites who developed Powassan virus encephalitis. As the authors point out, their case report not only demonstrates that rapid transmission of POWV can occur, but it highlights the importance for parents/caregivers to

Individuals who suffer from persistent symptoms may be diagnosed with a post-treatment lyme disease syndrome or ‘chronic Lyme disease.’  Studies estimate that between 34% and 62% of patients continue to have ongoing, chronic symptoms even after standard antibiotic therapy. Many remain ill for months to years. In fact, according to one study, 34% of a

Borrelia miyamotoi (BM) is another tick-borne pathogen and “unlike Lyme disease, erythema migrans rash, and arthralgias are uncommon,” the authors write in the journal Frontiers in Medicine. The infection is diagnosed with polymerase chain reaction (PCR) called glycerophosphodiester phosphodiesterase (GlpQ) enzyme immunoassay. Investigators looked at the incidence of BM in 82 patients who were seeking a

The Infectious Disease Society of America (IDSA) and the International Lyme and Associated Diseases Society (ILADS) have each published their own set of evidence-based treatment guidelines. IDSA guidelines recommend a short course of antibiotics, typically 14 to 30 days. IDSA argues that the Borrelia burgdorferi bacteria does not persist in a patient beyond this timeframe

In the article, “Pathogens Manipulating Tick Behavior—Through a Glass, Darkly,” Benelli reviews the literature on tick behavior triggered by infections with Anaplasma, Borrelia, Babesia, Bartonella, Rickettsia, and tick-borne encephalitis virus (TBEV).¹ You might think a deer tick would be worse off if infected. But, not so. It appears that deer ticks are actually more likely

Today, ticks harbor multiple infectious pathogens that can be transmitted to humans through a tick bite or tainted blood transfusion. The Centers for Disease Control and Prevention (CDC) now reports that “a single tick can transmit multiple pathogens, including bacteria, viruses, and parasites.” [1] This can result in patients developing what is referred to as

While many people associate Lyme disease with manifestations such as Bell’s palsy, the circular Bull’s-eye rash, and flu-like symptoms, Lyme disease can also cause sensory, cognitive, neurologic, and cardiac complications, even in its earliest stage. But, the signs and symptoms of Lyme disease are all too frequently attributed to another medical condition. Objective signs of

Lyme disease is an infection caused by the bacteria Borrelia burgdorferi (Bb), a spiral-shaped organism. The bacterium can be transmitted to a person through the bite of an infected Ixodes scapularis tick (a.k.a., the deer tick or black-legged tick). Borrelia burgdorferi bacteria is a type of spirochete that can penetrate virtually any organ or system

LYMErix was reportedly effective at preventing a Lyme disease rash. But the Lyme disease vaccine for humans was only 50% effective at preventing other manifestations of Lyme disease, according to the LYMErix package insert. LYMErix was voluntarily removed from the market due to low demand. In a survey of 1,015 adults in the U.S., author
