Portland, Maine, Launches Cruise Ship Outbreak Text Alerts

Portland, Maine, has launched an opt-in text-alert system to notify the public of infectious disease outbreaks aboard cruise ships scheduled to call at the city. The system follows the October 2025 arrival of Oceania Insignia with a norovirus outbreak that exceeded a U.S. Centers for Disease Control and Prevention threshold.

Portland recorded 133 ship calls and 200,801 passenger days in the latest CruiseMaine annual report, leading the state in cruise visitation despite a decline from its previous peak.

Portland Cruise Control proposed the system. Co-founder JoAnn Locktov said the group was concerned about the potential effects of an outbreak on residents, visitors and employees, particularly those working in the Old Port.

“We’ve invited these floating cities into our harbor, so we have to be responsible for the consequences of that,” Locktov said.

City Councilor Wes Pelletier said the program is intended to address both public health and tourism safety. He also questioned whether cruise operators would consistently provide the public with sufficient information about onboard outbreaks.

“With the data we have and with the resources we have, we’re going to make sure that residents can take the precautions that they need,” Pelletier said.

Portland Cruise Control is seeking additional measures beyond the alert program, including published thresholds governing whether ships may dock during an outbreak, defined quarantine procedures and enhanced sanitation standards. The city’s announced system does not yet include them.
