Malaria and its control: present situation and future prospects.

Area of Science:

• Public Health
• Tropical Medicine
• Epidemiology

Background:

• The World Health Organization's (WHO) global malaria eradication program, initiated in 1957, achieved success in temperate zones but encountered significant obstacles in tropical regions by the late 1960s.
• Technical challenges, including insecticide resistance in mosquito vectors and drug resistance in malaria parasites, coupled with administrative and financial constraints in developing nations, necessitated a revised strategy.
• Consequently, the WHO recommended a transitional approach in 1969, advocating for malaria control operations where eradication was not feasible, utilizing all effective methods against the parasite and vector based on local conditions.

Purpose of the Study:

• To evaluate the evolution of global malaria control strategies from eradication to integrated primary health care.
• To assess the effectiveness and challenges of implementing malaria control within primary health care systems in developing tropical countries.
• To highlight the essential components for successful malaria control, including government commitment, community support, inter-sectoral cooperation, staff training, and health education.

Main Methods:

• Historical review of global malaria control policies and strategies.
• Analysis of epidemiological trends and challenges in malaria-affected regions, particularly tropical areas.
• Examination of the integration of antimalarial activities into primary health care systems and influencing factors.

Main Results:

• Despite initial successes, malaria eradication faced significant setbacks in tropical countries due to vector and parasite resistance, and resource limitations.
• The malaria situation has deteriorated in several parts of Asia and Latin America, with no improvement in tropical Africa over the past decade.
• Since 1978, malaria control has been increasingly integrated into primary health care, aiming to reduce morbidity and mortality, though integration effectiveness varies based on diverse factors.

Conclusions:

• Malaria eradication remains a long-term goal, but pragmatic malaria control, integrated into primary health care, is crucial for developing tropical countries.
• Successful malaria control within primary health care requires strong governmental and community commitment, inter-sectoral collaboration, and targeted interventions.
• Effective integration depends on adapting strategies to specific epidemiological, socioeconomic, and cultural contexts, supported by trained personnel and community health education.
