OSAKA, Japan, December 22, 2023 - Shionogi & Co., Ltd. (Head Office: Osaka, Japan; Chief Executive Officer: Isao Teshirogi, Ph.D.; hereafter "Shionogi") announced that, the signing of a contract with African Mothers Co., Ltd. (Head Office: Tokyo, Japan; Chief Executive Officer: Yasuo Kawabata; hereafter "African Mothers") and Associate Professor Hidenori Harada (Graduate School of Asian and African Area Studies, Kyoto University) for the development of a water, sanitation and hygiene (WASH) education solution aimed at preventing diarrhea in the United Republic of Tanzania (hereinafter referred to as "Tanzania"), as part of the third phase of the Mother to Mother SHIONOGI Project (hereafter “this project”), an initiative dedicated to maternal and child support activities in Africa.

This project which has worked to maternal and child health in Africa since 20151-3 , is continuing its efforts in the third phase of the project4, which began in June 2023. This phase focuses on improving healthcare access in Kenya and Ghana, as well as reducing diarrhea among children.

Diarrhea disease is the fourth leading cause of death among children under five years of age in the world, following pneumonia, preterm birth complications, and birth asphyxia/birth trauma. It has a significant impact on the health of children in Africa, including Tanzania5. The occurrence of diarrhea in children can be attributed to multiple factors, such as knowledge of disease and hygiene among mothers, as well as variations in the initiation of breastfeeding6. Therefore, we have initiated an app development project for diarrhea prevention in Tanzania, where the penetration of smartphone has been increasing7,8. We will verify its effectiveness and consider expanding the project to other countries and regions in Africa.

Shionogi has identified “Improve access to healthcare” as one of the materiality (material issues) to be addressed. We are working to contribute to improving access to AMR treatment and supporting maternal and child health in Africa toward the realization of a sustainable society while further enhancing collaboration with international partners and other activities. Shionogi, with its commitment to improving global health, will leverage the insights and network gained through this project. We will collaborate with various partners to address the pressing issues related to maternal and child health, particularly in low- and middle-income countries. Our focus will be on enhancing healthcare access, improving sanitary environment and preventing childhood diarrhea. Through these efforts, Shionogi aims to contribute to the realization of Universal Health Coverage in Africa.
