Children are especially vulnerable to malnutrition and diseases related to poor sanitation. With the breakdown of health systems there have been outbreaks of highly contagious diseases like measles and even polio. The lack of immunizations only adds to the dangers children face in a country at war. They are also extremely vulnerable to sexual exploitation. Many of the children have had no schooling for more than three years. The schools that do exist lack teachers. Many schools have been bombed and shut down. The horrific things children have witnessed and experienced have traumatized them with emotional scarring to last a lifetime. They are faced daily with nightmares and isolating behaviours that continue the cycle of damage.
