诺如病毒在游轮上的传播。

An outbreak of norovirus gastroenteritis affected passengers on two consecutive cruises of ship X and continued on 4 subsequent cruises despite a 1-week sanitization. We documented transmission by food and person-to-person contact; persistence of virus despite sanitization onboard, including introductions of new strains; and seeding of an outbreak on land.

一艘X号邮轮连续两次航行期间，诺如病毒胃肠炎爆发，影响了船上乘客，尽管进行了为期一周的消毒处理，但在随后的4次航行中疫情仍在持续。我们记录了通过食物和人际接触传播的情况；尽管船上进行了消毒，包括出现新毒株，病毒仍持续存在；并且疫情还蔓延到了陆地上。
