    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    There are limitations to this approach; however, our methods are designed to foster dialogue on the ideal methods for transmission and to provide a basis for a joint methods standard for assessing transmission and its reporting A better understanding of transmission dynamics is essential for pandemic planning as with influenza and other respiratory agents. For example, if a substantial proportion of transmission occurs from individuals who at the time have no symptoms, some control measures such as quarantine and contact tracing might have doubtful value, especially if the duration of infectiousness is brief, but infectivity high, a pattern that fits with the infection of the youngest groups of infected people22. The prolonged period of potential infectiousness reported by Murata et al.23 in one of the elderly asymptomatic subjects from the Diamond Princess cruise ship should also be investigated in other settings as it may explain the sudden onset of epidemic foci in nursing homes several days after admission of the last patient to the institution. Again, a single “entry” point test may not be enough. Furthermore, the potential for the elderly to present with more subtle symptoms that may go unrecognized and with a prolonged infectious period is important to understanding and containing outbreaks in care homes.
