Cases like this where people tested positive out of the blue without knowing where the contact was made, makes me think containment will ultimately fail.

A man visiting from Japan tested positive for the Coronavirus after returning home, Hawaiian Airlines confirms the man traveled from Kahului to Honolulu on February 3 on flight HA 265 and they are reaching out to crew and agents who supported this particular flight.

A taxi driver has died from the coronavirus in Taiwan, marking the first such death on the island and the fifth fatality outside mainland China from an epidemic that has curbed travel and disrupted global supply chains.
The man who died had not travelled abroad recently and was a taxi driver whose clients were mainly from Hong Kong, Macau and mainland China, the minister said. One of his family members was also confirmed to have the virus.
