TB Screening Recommended for High-Risk Healthcare Workers Only
Routine screening for and treatment of latent tuberculosis (TB) infection has traditionally been an important part of TB prevention in Canadian and US healthcare institutions, but recent data have called into question its cost effectiveness. A new study has found that the current strategy of annual screening of is ineffectively expensive, suggesting that a switch to screening only high-risk healthcare workers is needed.

New Test Distinguishes Zika from Similar Viral Infections
Zika is a mosquito-borne disease and is linked to severe congenital birth defects. Assays already exist to detect Zika virus infection, but they either work only shortly after infection or are poor at differentiating Zika from other flaviviruses. More...02 Aug 2017

Powassan Virus Diagnosed in Patients with Tick-Borne Diseases
Powassan virus (POWV) lineage II, also known as deer tick virus, is an emerging tick-borne flavivirus transmitted by Ixodes scapularis ticks, which are also the primary vector for the Lyme disease pathogen Borrelia burgdorferi. More...02 Aug 2017

Antimicrobial Therapy Biomarker Enumerates Eosinophil Count Changes
Eosinopenia as a criterion of sepsis has been the subject of debate for decades and the pathophysiology of eosinopenia is related to the migration of eosinophils to the inflammatory site, presumably as a result of chemotactic substances secreted during the acute phase of inflammation.

Accuracy of Malaria Tests Evaluated for Febrile Children
It remains challenging to distinguish malaria from other fever causing infections, as a positive rapid diagnostic test does not always signify a true active malaria infection. Antigen persistence could increase the rate of false positive test results, leading to a wrong diagnosis in settings where other diagnostic tools are unavailable. More...01 Aug 2017

Efficacy Evaluated in Maternal Screening for Congenital CMV
Researchers have evaluated for the first time the efficacy of maternal universal screening using cytomegalovirus (CMV) IgG avidity tests for congenital CMV infection, and they have also identified problematic issues with the current maternal CMV screening methods. More...31 Jul 2017
