Reduce Norovirus Burden
Human noroviruses are a large family of viruses and are leading causes of acute gastroenteritis (AGE) in all age groups worldwide. They have replaced rotavirus as the most common causes of AGE in children. Our research team is committed to studying molecular epidemiology and pathogenesis of human noroviruses. We have been working on monitoring emergence of novel strains. This will form scientific foundation for vaccine strain selection in the region. We are also working on teasing out host factors important for norovirus replication using intestinal organoids as models. This will better our understanding on disease-causing mechanism of noroviruses with insights into developing antiviral drug intervention to ultimately reduce norovirus burden.
