KATHMANDU, July 13 (Xinhua) -- Viral fever has gripped all seven Bhutanese refugee camps in eastern Nepal. Hundreds of refugees have fallen ill and treatment of the sick has become difficult as most of them are children and aged people, The Himalayan Times reported on Friday.

    According to the daily, the number of patients visiting health centers in the camps has gone up suddenly and there are neither enough health workers to attend to the sick nor sufficient medicines, said a health worker, Bidur Dagal, adding that at least 100 patients were visiting the health centers every day.

    He was warning that the situation can get out of hand if arrangements for treatment are not made soon.

    Some 106,000 Bhutanese refugees have been living in seven camps in eastern Nepal for the last 16 years.
