Damaged infrastructure contributes to the spread of communicable diseases, including those previously eradicated, such as poliomyelitis in Syria recently, and prevents people from receiving curative or preventive health care, which then leads to spikes in NCDs. Access to food and safe drinking water may also be reduced. Internally displaced persons and refugees are particularly vulnerable to ill health because they generally live in poor conditions in which diseases spread easily, and access to health services is minimal.
