Meanwhile, the French Polynesian government said the woman had transited through without notifying “territorial and national authorities”. Authorities held an emergency meeting on Sunday and decided not to allow the woman now isolating on Pitcairn to re-enter French Polynesia.
“Although she is currently completely asymptomatic and therefore not contagious, (she) will not leave Pitcairn Island to travel through French Polynesia as long as she poses a risk to others,” it said.
French Polynesia said passengers on the same flight as the woman from San Francisco to Tahiti were not considered close contacts and “the risk of infection is considered very low”.
