According to Hawaii health officials, a resident who had traveled outside the community tested positive after flying home in December, ending Kalawao County’s impressive run.

Though most of Kalawao County is now a national park, roughly a dozen survivors still live there today, in the care of the state.

They all have other health issues, so they’re at extreme high risk for covid mortality,” Baron Chan, the branch chief for Hansen’s disease at the Hawaii Department of Health, told KHON in October.

Before the pandemic, Kalawao County had roughly 100 residents, including National Park Service employees and health workers, Chan told the station.

But as many as half that number have left since early March, when state health officials took aggressive measures to protect the remaining residents who were once Hansen’s disease patients.

In fact, Kalawao was already so committed to following public health guidelines that the discovery of the first coronavirus case didn’t make much of an impact, locals told the Maui News.
