Three Burmese refugees have died and seven others have fallen victim to meningitis, an infection of the brain and spinal fluid.
The outbreak was reported in Thailand's Umphang district of Tak, about 425 kilometers northwest of Bangkok. Authorities have quarantined the Nu Pho refugee camp, which is home to some 10,000 displaced Burmese people.
A Tak public health official says the outbreak was detected last year but worsened this week. As a result, health officials started a vaccination campaign and have barred anyone from entering or leaving the camp.
Meningitis is a bacterial or viral infection of the brain and spinal chord that causes fever, vomiting, intense headache, and a stiff neck.
