Blood donor West Nile virus screening identifies three autochthonous Usutu virus infections in Spain

Transfusion, EarlyView.
Abstract Background Considering the increase of West Nile virus (WNV) circulation in Europe, blood banks perform WNV Nucleic Acid Test testing to ensure transfusion safety during the WNV transmission season. Usutu virus (USUV), an arbovirus related to WNV, has relevant molecular and serological cross‐reactivity with WNV. Study Design and Methods During

Chikungunya Virus Diagnosis: A Review of Current Antigen Detection Methods

Tropical Medicine and Infectious Disease, 2023
Chikungunya is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV). CHIKV is expanding at an alarming rate, potentially spreading and establishing endemicity in new areas where competent vectors are present.

Dengue, chikungunya and Zika virus surveillance in blood donors in Brazil, 2019–2021

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Arbovirus infections are a major public health concern in Brazil and an ongoing blood safety concern. Periodic outbreaks of such infections are common in the general population. This study aimed to establish the rates of dengue, chikungunya and Zika virus (DENV, CHIKV, ZIKV) RNAemia among blood donors at six public ...

Bee products as alternatives in the treatment of viral infections

Journal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 33-54, 15 January 2026.
Abstract Medicines used in the treatment of viral infections usually reduce symptoms. There is a need to develop drugs that inhibit the viruses and do not merely relieve the symptoms. Natural bee products possess many pharmacological properties and are widely used in folk medicine. There are many studies on the antibacterial effects of bee products but

Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...
