The bacterium that has been causing cholera in Vietnam since 2007 is growing more toxic and dangerous, the Ministry of Health reported on Monday.
The current strain of V.cholare is different from that which caused the acute intestinal disease in Vietnam before 2007, according to the ministry, which noted that the new type has a far longer lifespan in the environment.
This year Vietnam has recorded 69 cholera cases in nine provinces and cities, including Hanoi and Ho Chi Minh City, deputy minister Trinh Quan Huan said Monday.
However, no deaths have been recorded Vietnam this year and currently only the Mekong Delta Province of Ben Tre is treating infections, according to Huan.
More cases will surely emerge, but the ministry stressed it had the situation under control.
