Cambodia is one of the poorest countries in Asia and children here are vulnerable. Suffering is a substantial part of life and children become prohibited from attaining their developmental potential. The whole environment affects the children's health in different grades. "Convention on the Right of the Child" declare that all children have the same right to the best health possible. Good health among children in Cambodia are a crucial issue for the future development of the country. The aim of this study was to illuminate healthcare worker´s experiences of children's health in Cambodia. The method was a qualitative interview study. The data was collected through interviews with seven health-care workers in Cambodia. The data was subjected to qualitative content analyse. The result shows the fact that children can die, the power of tradition and absence of parental influence all have a negative effect on children´s health. There were also experiences of improvements for the children´s health. The challenges brought feelings of despair but there were also feelings of hope when the healthcare workers experienced opportunities for the children to obtain health. The conclusion was that healthcare workers were hovering between hope and despair towards the health of the Cambodian children.
