The Blacklegged Tick, Ixodes scapularis: An Increasing Public Health Concern.

The Blacklegged Tick, Ixodes scapularis: An Increasing Public Health Concern. Trends Parasitol. 2018 Jan 11;: Authors: Eisen RJ, Eisen L Abstract In the United States, the blacklegged tick, Ixodes scapularis, is a vector of seven human pathogens, including those causing Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi disease, Powassan virus disease, and ehrlichiosis associated with Ehrlichia muris eauclarensis. In addition to an accelerated rate of discovery of I. scapularis-borne pathogens over the past two decades, the geographic range of the tick, and incidence and range of I. scapularis-borne disease cases, have increased. Despite knowledge of when and where humans are most at risk of exposure to infected ticks, control of I. scapularis-borne diseases remains a challenge. Human vaccines are not available, and we lack solid evidence for other prevention and control methods to reduce human disease. The way forward is discussed.

ConclusionResults illustrate the potential impact that individualization of case management directed toward postpartum WLWH could have on future outcomes. Scale up of a low effort, low cost intervention such as the one conducted at this clinic could significantly improve the retention and viral suppression rates of postpartum WLWH in the United States; specifically, in the Southern region where retention and viral suppression rates remain exceedingly low.

Conclusions: The findings highlight an enhanced risk of alcohol and substance use among individuals with severe depression and/or anxiety symptoms above what is seen among individuals with less severe symptomatology. In addition, this study shows a unique risk posed by the presence of depression on substance use. This study offers a framework for future studies to examine the causal mechanisms explaining the connection between psychiatric symptoms and alcohol/substance use.

Abstract Ixodes scapularis is currently known to transmit 7 pathogens responsible for Lyme disease, anaplasmosis, babesiosis, tick-borne relapsing fever, ehrlichiosis, and Powassan encephalitis. Ixodes scapularis can also be colonized by endosymbiotic bacteria including those in the genus of Rickettsia. We screened 459 I. scapularis ticks submitted to the Connecticut Agricultural Experiment Station Tick Testing Laboratory with the objectives to (1) examine differences in infection prevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and Borrelia miyamotoi, (2) evaluate whether prevalence...
