The latest case is a 22-year-old Vietnamese student recently returning to the country from Britain, said the ministry, noting that he was quarantined upon arrival and is being treated in the southern Ho Chi Minh City.
A total of 307 patients in the country have totally recovered from the disease as of Saturday, according to the ministry.
Vietnam has recorded no local transmission for 51 straight days while there are nearly 9,100 people being quarantined and monitored in the country, said the ministry.
Meanwhile, Police of Vietnam's northern Son La province have detained a local man for trading two heroin cakes and some 6,000 pills of lab-made drug, Vietnam News Agency reported.
The 52-year-old dealer was caught red-handed transporting the illicit drugs in the province's Bac Yen district on Wednesday, according to local authorities. Further investigation is underway.
About 300km from Hanoi, Son La province is notorious as a drug hotspot, with around 1,000 cases and hundreds of kilogrammes of narcotics seized every year, said the news agency.
According to the Vietnamese law, those convicted of smuggling over 600 grams of heroin or more than 2.5 kg of methamphetamine are punishable by death. Making or trading 100 grammes of heroin or 300 grammes of other illegal drugs also faces death penalty. - Xinhua/Asian News Network
