Recent Advances in Lateral Flow Immunoassay for Rapid Diagnosis of Viral Diseases

Viral diseases are a major threat to human and animal health, as illustrated by recent pandemics like COVID-19 and African swine fever (ASF). Timely, accurate detection of viral infections is critical for effective disease control. Among diverse diagnostic techniques, lateral flow immunoassay (LFIA) has become a widely used on-site testing tool, owing to its speed, simplicity, affordability, and portability. The application of LFIA for detecting human and animal viruses is feasible, which highlights its practical utility in veterinary settings. This review summarizes key advances in LFIA for the rapid diagnosis of viral diseases over the past decade, focusing on its technical principles, practical applications, core advantages, existing limitations, and potential effective strategies to provide comprehensive knowledge for virus detection.
