Inability to access health care: The poor always tend to have worse health. The Cambodian poor are holding a heavy burden of bad health and diseases. The poor are likely to live within unhygienic; they are less understanding about good health and hygiene, and less likely to have the resources to ensure healthy life-styles, e.g. water, sanitation, foods, prophylaxis, etc. The primary causes of death for the general population are malaria, acute respiratory infection, tuberculosis, diarrhea and dengue fever. HIV/AIDS is also a main factor that contributes to low life expectancy among Cambodian citizens. Life expectancy at birth is estimated at only 57 years, about 13 years less than the life expectancy average in the region
