Unmanageable norovirus outbreak in a single resort located in the Dominican Republic.

Noroviruses constitute an important cause of acute gastroenteritis, mainly in semi-closed populations such as hospitals, hotels and cruise ships. This study records the most important norovirus outbreak in the Dominican Republic in a single resort, with more than 800 people being affected in a 15-day period. Analysis of clinical and environmental samples demonstrated that norovirus was the aetiological agent responsible for the outbreak. Although enhanced hygiene and disinfection measures were achieved, the outbreak was only controlled after suspension of entry into the resort.
