2.4 Health in Developing Countries

Health challenges in developing countries are complex and interconnected. From maternal mortality to neglected tropical diseases, these issues stem from poverty, limited resources, and weak health systems. Addressing them requires a multifaceted approach.

Improving healthcare access, combating malnutrition, and strengthening public health infrastructure are key strategies. By focusing on these areas, developing countries can make significant strides in improving overall population health and well-being.

1 of 2

• Health inequities stem from social determinants of health lead to unfair and avoidable differences in health outcomes
• Socioeconomic factors (income, education, occupation) significantly influence health status and access to healthcare services
• Geographic disparities result in rural populations often facing limited access to medical facilities and healthcare professionals
• Healthcare access barriers include financial constraints, lack of transportation, and cultural or linguistic differences
• Universal health coverage aims to ensure all individuals receive essential health services without financial hardship
• Primary healthcare forms the foundation of a strong health system provides comprehensive, continuous, and coordinated care
• Community health workers bridge the gap between formal health systems and underserved populations offer culturally appropriate care and health education

Strategies for Improving Healthcare Access

• Telemedicine expands access to medical expertise in remote areas through virtual consultations and remote monitoring
• Mobile health clinics bring essential services to underserved communities overcome geographical barriers
• Task-shifting involves training non-physician healthcare workers to perform specific medical tasks addresses healthcare worker shortages
• Public-private partnerships leverage resources and expertise from both sectors to improve healthcare infrastructure and service delivery
• Health insurance schemes (community-based, national) reduce financial barriers to accessing healthcare services
• Capacity building programs enhance the skills of local healthcare workers strengthen the overall health system
• Integration of traditional medicine with modern healthcare practices improves cultural acceptability and accessibility of health services

Maternal, Child, and Neglected Diseases

Addressing Maternal and Child Health Challenges

• Maternal mortality remains a significant concern in developing countries often caused by preventable complications (hemorrhage, infection, hypertensive disorders)
• Antenatal care provides essential health services and education for pregnant women reduces risks of pregnancy-related complications
• Skilled birth attendance ensures safe deliveries and immediate postpartum care crucial for reducing maternal and neonatal mortality
• Child health interventions focus on reducing under-five mortality rates through immunization programs, nutrition support, and management of childhood illnesses
• Integrated Management of Childhood Illness (IMCI) approach combines prevention and treatment strategies for common childhood diseases
• Breastfeeding promotion and support improves infant nutrition and immunity reduces risk of infections and malnutrition
• Family planning services enable women to make informed choices about reproduction contribute to improved maternal and child health outcomes

Combating Malnutrition and Neglected Tropical Diseases

• Malnutrition manifests as undernutrition, overnutrition, or micronutrient deficiencies affects physical and cognitive development
• Stunting (chronic malnutrition) results from long-term nutrient deficiencies impairs growth and development in children
• Wasting (acute malnutrition) occurs due to recent rapid weight loss or failure to gain weight requires urgent intervention
• Micronutrient fortification programs address deficiencies in essential vitamins and minerals (iron, vitamin A, iodine)
• Neglected tropical diseases (NTDs) affect over a billion people worldwide often in impoverished communities
• Common NTDs include lymphatic filariasis, onchocerciasis, schistosomiasis, and soil-transmitted helminthiases
• Mass drug administration campaigns target entire at-risk populations to control and eliminate NTDs
• Vector control measures (insecticide-treated bed nets, indoor residual spraying) help prevent transmission of vector-borne NTDs

Public Health Infrastructure

Improving Water, Sanitation, and Hygiene (WASH)

• Access to clean water, adequate sanitation, and proper hygiene practices form the foundation of public health
• Water treatment methods (chlorination, filtration, solar disinfection) improve water quality at household and community levels
• Improved sanitation facilities (toilets, latrines) prevent contamination of water sources reduce the spread of waterborne diseases
• Handwashing with soap at critical times (before eating, after using the toilet) significantly reduces disease transmission
• Community-led total sanitation (CLTS) approach engages communities in identifying and addressing their sanitation challenges
• WASH in schools programs ensure access to clean water and sanitation facilities promote hygiene education among children
• Menstrual hygiene management addresses the specific needs of women and girls promotes dignity and school attendance

Implementing Sustainable Development Goals and Health System Strengthening

• Sustainable Development Goals (SDGs) provide a comprehensive framework for addressing global health challenges by 2030
• SDG 3 (Good Health and Well-being) encompasses targets for reducing maternal and child mortality, ending epidemics, and achieving universal health coverage
• Health system strengthening involves improving six core components (service delivery, health workforce, information systems, medical products, financing, leadership/governance)
• Health information systems enable data-driven decision-making and resource allocation improve overall health system performance
• Supply chain management ensures the availability of essential medicines and medical supplies at all levels of the health system
• Health financing mechanisms (tax-based, social health insurance, community-based insurance) aim to achieve sustainable and equitable healthcare funding
• Governance and leadership in health systems involve developing and implementing effective policies, regulations, and accountability measures
