Genetic diversity and persistent transmission of norovirus in Shenzhen, China, 2016–2018

We read with interest the report in this Journal by Elgner and colleagues which emphasizes the critical role of person-to-person transmission in the epidemiology of Norovirus infection.1 Imported cases can rapidly spread allowing novel clones to disseminate rapidly. In the following, we will describe the genetic diversity and persistent transmission of norovirus in Shenzhen, China.
