Multinational Injury Surveillance System Pilot Project Opportunities Response to WHO recommendations/observations in that: Response to WHO recommendations/observations in that: Many countries, specially in underdeveloped regions lack injury surveillance systems that would provide reliable data on injury. Call for enhancing capacity for collecting data on violence at the national level in developing countries Lack of data has made multinational comparisons difficult.
