Norovirus detection is a research area focused on developing methods and technologies to identify and detect the presence of norovirus, a highly contagious virus that causes gastroenteritis in humans. This research involves the use of various techniques such as nucleic acid amplification, immunoassays, and electron microscopy to detect the virus in clinical samples, food, water, and environmental surfaces. Improved detection methods are essential for preventing outbreaks of norovirus and implementing effective control measures.
