After Nearly Erasing COVID-19, Vietnam Grapples with a Spike Ralph Jennings TAIPEI, TAIWAN - Vietnamese officials are rushing to control a sudden new outbreak of COVID-19 after reporting one of the world's most successful control efforts earlier in the year. Authorities in the Southeast Asian country sealed off the central coast tourist city Danang Sunday after two people tested positive for the deadly atypical pneumonia, domestic media reports say. The new spike in and near Danang had grown to 30 cases as of early Wednesday, mostly traced to a local hospital. People elsewhere in the economically booming country of 97 million worry that the Danang infections will spread outward and spark another nationwide shutdown like the one ordered for about a month through late April. "It could be another outbreak, and it's really sort of scared the Vietnamese, because they thought they'd gotten through it all, but as the rest of the world discovered, this thing spreads much quicker than you think," said Adam McCarty, chief economist with Mekong Economics in Hanoi. While Vietnam's latest figures still hardly match the hundreds of daily cases still being reported in much of the world, the country prides itself on throttling the disease earlier in the year with no deaths to date. Vietnam had gone without transmission for 99 days through Saturday and its domestic economy roared back to life by May. Halts to flights and strict quarantine rules have kept the overall caseload to 446 including the latest outbreak. As of Tuesday, 369 people had recovered. .
