Malaria Rapid Test Evaluated in Low Transmission Area

Light microscopy detecting human malarial parasites in Giemsa-stained thick and thin blood films still remains the gold standard for malaria diagnosis. In many peripheral health centers of endemic countries, microscopy is not available due to limited resources or lack of expertise. More...

Review Provides Insight into Therapeutic Interventions

A new review has outlined recommendations and a gold standard for identifying at-risk patients who are critically ill, or in receipt of organ transplants, for preventing, diagnosing and treating invasive fungal infections. It was published as part of a set of papers intended to provide new insights into the breadth of serious fungal diseases and as a call to world health bodies to prevent millions of infections each year.

Biosensor Device Developed for Zika Diagnosis

A novel plasmonic biosensor-based detection system was developed that can diagnose recent or current Zika virus (ZIKV) infection in 15 minutes or less. More...
