A couple was arrested at a Hawaii airport for travelling on a flight from California despite knowing they were infected with COVID-19, authorities said. They boarded a United Airlines flight to Lihue with a 4-year-old child after San Francisco International Airport officials told them Sunday to isolate themselves and avoid the flight, the Kauai Police Department said.

Police escorted Wesley Moribe, 41, and Courtney Peterson, 46, to a designated isolation room after the plane landed, where they were arrested on suspicion of second-degree reckless endangering.

The residents of Wailua on Kauai were released after posting US $1,000 bail each.

The child was released into the care of a family member and the Child Protective Services division of the state Department of Human Services was notified.

Moribe and Peterson took COVID-19 detection tests before the flight as part of Hawaii’s pre-travel testing program, officials said.

They both tested positive for the virus and were taken to the San Francisco airport’s quarantine station and told not to fly.

“They knowingly boarded a flight aware of their positive COVID-19 test results, placing the passengers of the flight in danger of death,” Kauai police said.

Peterson did not immediately return voicemail messages Thursday seeking comment. A phone number associated with Moribe had been disconnected.

Democratic Gov. David Ige last week approved Kauai Mayor Derek Kawakami’s request to temporarily allow the island to opt out of the state testing program.

The policy scheduled to take effect Wednesday requires travellers to Kauai to spend 14 days in quarantine regardless of whether they obtain a negative COVID-19 test.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems it can cause more severe illness, including pneumonia, and death.
