The Bourbon virus (BRBV), believed to be transmitted through tick or insect bites, was first identified in a Kansas man in 2014, who eventually died due to complications from the disease. And while only a handful of people have reportedly developed the virus, two have died from it.
The number of cases of Lyme disease in Maine have been growing over the past 3 decades with 1,848 patients diagnosed in 2017, according to Maine Center for Disease Control and Prevention. This is an increase of 23% since 2016. But other tick-borne diseases are causing concern, as well, including anaplasmosis, babesiosis, Borrelia miyamotoi and the Powassan virus, which killed a Maine woman in 2013.
In August of 2013, a 17-year-old boy died suddenly from cardiac arrest. Initially, health officials blamed the Powassan virus for his death. But a recent report in Cardiovascular Pathologist finds that the young man died instead from Lyme carditis.
Evidence of a Powassan virus infection affecting the spinal cord has, until now, only been seen in mouse studies. But a new article describes the first known case of a 62-year-old man from Canada who developed a polio-like illness caused by the Powassan virus (POWV).
Ever wonder why some people are more likely to be bitten by a tick than others? Researchers in the Czech Republic claim it may have to do with a person’s blood type. “The influence of blood groups on certain diseases such as malaria or some cancers has been already discussed and proved,” the authors point out. Type O blood has been linked to the slow progression of malaria, transmitted by mosquitoes. “This may suggest that there could be a similar relationship between tick-borne diseases and some blood group(s).”
Under the 2016 21st Century Cures Act, academic and government scientists, physicians, along with patient advocates, came together and formed the Tick-Borne Diseases Working Group. The group's mission was to develop recommendations to combat the spread of Lyme and other tick-borne diseases.
Concerned about the over diagnosis of Lyme disease in France, Haddad and colleagues respond to a recent article discussing the treatment of 478 patients consulted for presumed Lyme borreliosis (LB) at a center in Nancy, France. In a Letter to the Editor, Haddad includes two other French studies and reports on their results. 
In their article “Co-infections in early Lyme disease,” Wormser and colleagues describe 52 adult patients with erythema migran rashes who were evaluated for the presence of co-infections. (Patients with extracutaneous manifestations were excluded.)
The authors of a recent review describe 9 cases of pediatric neuroborreliosis (NB) collected by the National Observatory of Pediatric Bacterial Meningitis in France between 2001 and 2012. The children, ages 4 – 13 years, presented with “meningeal irritation alone or with facial palsy, or isolated facial palsy, writes Guet-Revillet and colleagues.  All of the cases were confirmed with a spinal tap.
This case report, featuring an 8-year-old boy, illustrates, once again, the unusual presentation that can occur with Lyme disease.  The child was admitted to the emergency department at Jefferson University Hospital in Philadelphia with swelling and pain in his knee and calf.
