Crisis situations due to disasters, including pandemic outbreaks such as the COVID-19, increase older person's vulnerability (Ministry of Health, 2020). This book provides guidelines for implementing the Minimum Health Service for Older Persons to meet the older persons' essential needs during crisis situations. The implementation of the Minimum Health Service for Older Persons (Pelayanan Minimum Kesehatan Lansia) during a health crisis is focused on three objectives, namely (1) To ensure the availability and accessibility of general health and reproductive health services for the older persons, (2) To improve the health and protection aspects for the older persons in displaced conditions, and (3) To meet other essential needs of the older persons through multi-sectoral partnerships: WASH (water, sanitation, and hygiene), evacuation/shelters and the availability of food. Coordination between the Health and Displacement and Protection Cluster is the key to having better preparedness, response, and recovery plans in meeting the minimum needs of older persons in health crisis situations.
