A week after Typhoon Lekima, hundreds of thousands of students are still prevented from attending classes, officials said Thursday.
Even though water levels on rivers in some central and northern provinces have begun receding, many areas remain inundated.
"For safety of the students, we have to close the schools until the water recedes completely," said Tran Van Ha, disaster official from northern Ninh Binh province.
Meanwhile, the bodies of three people, including two students were recovered Wednesday in central province of Ha Tinh, bringing the death toll from the typhoon and flooding to 89 with 10 others still reported missing, said provincial disaster official Tran Duc Thinh.
Floods washed away nearly 10,000 homes and submerged or damaged nearly 130,000 others, the Department of Floods and Storms Control said, adding the flooding also damaged 370,000 acres of rice and other crops.
Local authorities are helping residents to clean up the environment and treat water, it said adding no major disease outbreaks have been reported in the affected provinces.
The department put the initial damage estimate from the typhoon at $131 million.
Vietnam is prone to floods and storms that kill hundreds of people each year.
