At least 15 COVID-19 community infection cases have been confirmed in four cities and provinces since April 29.

All the above cases are linked to a 28-year-old man who tested positive after completing 14-day mandatory quarantine in the central city of Da Nang.

He flew from Japan to Da Nang on April 7 and was quarantined in Da Nang until April 22 when he was allowed to his turn to his native land of Ha Nam Province.

As currently regulated, the man must isolate himself at home for another 14 days but he had a party with his family members and friend on April 22.

In addition, on Sunday afternoon, the northern province of Vinh Phuc reported five community infection cases, all linked to a Chinese national who also tested positive for COVID-19 after 14-day mandatory quarantine period in Yen Bai Province.

The two latest outbreaks are likely to spread to other localities as people are now on four-day long public holiday, starting from April 30.

Many localities still allow mass gatherings at public places such as beaches, entertainment and tourists sites where preventive measures are not seriously implemented, especially mask wearing.

The ministry asked localities to consider closing non-essential services like bars, karaoke parlors, discotheques, and game rooms and strengthen inspection of mask wearing at public places./.
