The Mother and Child Tracking System (MCTS) is an Indian government initiative to track maternal and child health beneficiaries and improve service delivery. It registers pregnant women and children under 5 for antenatal care, delivery care, postnatal care, and immunizations. Frontline health workers use MCTS to generate work plans, ensure all beneficiaries receive scheduled services, and update the system in real time. Over 2.8 crore mothers and 2.06 crore children have been registered in MCTS so far. The government aims for 100% registration and updating of services provided through the system.
