   Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:

   Our findings and interpretations should take into consideration the following limitations. First, it took approximately three hours to bring the specimen to the laboratory due to logistical challenge in a cruise ship, which may affect the viral isolation. Second, we could not directly measure the temperature and humidity in the cruise ship. In conclusion, the environment around the COVID-19 cases was extensively contaminated from SARS-CoV-2 during COVID-19 outbreak in the cruise ship. The environmental surface could involve viral transmission through direct contact, but may not be through air or wastewater mechanisms. This transmission can occur from persons who are asymptomatic at the time of specimen collection. Cleaning of surfaces with hydrogen peroxide-based products and communication messages demonstrating and emphasizing hand hygiene are essential to interrupting the chain of transmission during outbreaks.
