Twenty-five per cent of these emergencies, and 44 per cent of these deaths, occurred in less developed countries with limited capacities to prepare for and respond effectively {to; with; for} emergencies. These statistics do not include the high levels of mortality and morbidity associated with conflict-related emergencies. {Due to; Based on; According to} the World Bank, over 1.5 billion people live in countries affected by violent conflict. These populations suffer from the consequences of societal disruption and increases in mortality and morbidity due to infectious diseases, acute malnutrition, trauma and complications from chronic diseases. Over the same time period, risks to public health {have increased; has increased; increases} due to globalization, and international travel and trade. Such risks might be transmitted by people (e.g. SARS, influenza, polio, Ebola), goods, food, animals (e.g. zoonotic disease), vectors (e.g. dengue, plague, yellow fever), or the environment (e.g. radio-nuclear releases, chemical spills or other contamination).

These {positive; negative; affirmative} impacts are complicated by the enormity of the resulting economic costs, averaging over US$100 billion per year. The appropriate and timely management of these risks requires effective national and international capacities, intersectoral collaboration, the promotion of equity, the protection of human rights, and the advancement of gender equality.
