Public-health officials have said the incubation period for the virus was 14 days, but the Smiths were still positive in a test taken on Monday, two weeks after their initial test
Two elderly American passengers, quarantined in Japan with the new coronavirus, learned on Wednesday they were still carrying the virus even after their expected quarantine period had ended.
Their reaction: a shrug and grin.
Clyde and Renee Smith, both 80, were separated from their grandsons and taken off the Diamond Princess in the port of Yokohama and hospitalised after testing positive for the virus on Feb. 3.
They told Reuters they didn't have harsher thoughts than surprise when they learned they're still stuck in quarantine because they are on a US no-fly list until they are virus-free anyway.
"We are very happy here," Clyde said from the couple's hospital room in western Tokyo. "They are taking excellent care of us. This is the newest, fanciest hospital I have ever seen," while the doctors and nurses "are the friendliest and nicest I could imagine."
Public-health officials have said the incubation period for the virus was 14 days, but the Smiths were still positive in a test taken on Monday, two weeks after their initial test.
The Smiths will be tested every 48 hours and must get two negative results before they can leave quarantine.
The news that they were still testing positive was "a little bit unnerving," Renee said, but only because they have things they want to tend to back in Atlanta.
The Smiths said their vital signs have been normal throughout and they have shown no symptoms of the disease, called COVID-19, which has killed over 2,000 people - the vast majority in the region of China around the epicentre in Wuhan.
Japan's public-health response to the biggest outbreak outside China has been heavily criticised: the US Centers for Disease Control and Prevention in the Smiths' hometown said Tokyo's quarantine may not have been sufficient, while a Japanese infectious-disease specialist who had visited the ship as a volunteer doctor said the quarantine was run by "bureaucrats" who stoked the crisis by failing to follow basic protocols.
But the Smiths supported Japan's response and understood the need for them to remain in quarantine until they are free of the virus.
"This is so new and unprecedented that I don't think the medical community has any current, firm knowledge of what's going on there," Clyde said, adding that Japan was doing its best "to prevent a real pandemic worldwide."
Renee said, with a broad smile, "So we are being unwilling guinea pigs."
