Vietnam's latest coronavirus outbreaks have seen 36 community transmissions since last week in six localities: Ha Nam, Hanoi, Hung Yen, Ho Chi Minh City, Vinh Phuc and Da Nang.
Hanoi has confirmed four community transmissions, three of them making contact with a Ha Nam man who returned from Japan and tested positive after completing his two-week centralized quarantine, and the other one making close contact with an infected Chinese expert on a flight from Da Nang to Hanoi on April 29.
The capital has suspended non-essential services like bars, karaokes and dance clubs, as well as street food vendors and cafes to prevent the disease from spreading.
