Dak Nong has so far recorded 12 diphtheria cases. All outbreak areas, including Krong No District's Dak Sor Commune and Dak Glong District's Dak R'mang Commune and Quang Hoa Commune, each one dozens of kilometers apart, have now been quarantined.
The diphtheria vaccination rate in Dak Nong is only around 52-65 percent, said Dang Thanh, director of the provincial Center for Disease Control. He attributed this to the H’Mong community not being cooperative about vaccination.
The province vaccinated around 4,800 residents of Quang Hoa, aged 7-40, against diphtheria and tetanus on Saturday. The people of Dak R'Mang are expected to be next.
Last year a seven-year-old girl in the Central Highlands province of Dak Lak, which neighbors Dak Nong, succumbed to the disease. In 2017 and 2018 six people died in the Central Highlands province of Kon Tum and the central province of Quang Nam.
Diphtheria vaccination is part of Vietnam's national immunization program but the regimen is not followed strictly in several areas for various reasons.
