Federal Democratic Republic of Ethiopia Ministry of Health Hygiene and Environmental Health, Part 1 Blended Learning Module for the Health Extension Programme HEAT Health Education and Training HEAT in Africa Federal Democratic Republic of Ethiopia Ministry of Health The Ethiopian Federal Ministry of Health (FMOH) and the Regional Health Bureaus (RHBs) have developed this innovative Blended Learning Programme in partnership with the HEAT Team from The Open University UK and a range of medical experts and health science specialists within Ethiopia. Together, we are producing 13 Modules to upgrade the theoretical knowledge of the country’s 33,000 rural Health Extension Workers to that of Health Extension Practitioners and to train new entrants to the service. Every student learning from these Modules is supported by a Tutor and a series of Practical Training Mentors who deliver the parallel Practical Skills Training Programme. This blended approach to work-place learning ensures that students achieve all the required theoretical and practical competencies while they continue to provide health services for their communities. These Blended Learning Modules cover the full range of health promotion, disease prevention, basic management and essential treatment protocols to improve and protect the health of rural communities in Ethiopia. A strong focus is on enabling Ethiopia to meet the Millennium Development Goals to reduce maternal mortality by three-quarters and under-5 child mortality by two-thirds by the year 2015. The Modules cover antenatal care, labour and delivery, postnatal care, the integrated management of newborn and childhood illness, communicable diseases (including HIV/AIDS, malaria, TB, leprosy and other common infectious diseases), family planning, adolescent and youth reproductive health, nutrition and food safety, hygiene and environmental health, non-communicable diseases, health education and community mobilisation, and health planning and professional ethics. In time, all the Modules will be accessible from the Ethiopian Federal Ministry of Health website at www.moh.gov.et; online versions will also be available to download from the HEAT (Health Education and Training) website at www.open.ac.uk/africa/heat as open educational resources, free to other countries across Africa and anywhere in the world to download and adapt for their own training programmes. Dr Kesetebirhan Admasu State Minister of Health Ethiopian Federal Ministry of Health i Acknowledgements Hygiene and Environmental Health is one of the 13 Blended Learning Modules for the Ethiopian Health Extension Programme.

But the way we do them can have a major impact on our health. Good hygiene practices are an essential part of daily life and we all need to understand what hygiene means, why it’s important for our health and wellbeing, and how we can change our behaviour to safeguard our health.
