Measuring malaria endemicity from intense to interrupted transmission

Area of Science:

• Epidemiology
• Public Health
• Malariology

Background:

• Quantifying malaria transmission is crucial for classifying malaria risk and guiding control efforts.
• Historical malaria endemicity indices were developed during the Global Malaria Eradication Programme.
• These indices informed action points for malaria control programs.

Purpose of the Study:

• To review the historical development of malaria endemicity indices.
• To assess the contemporary relevance of these indices for current malaria control strategies.
• To inform discussions on malaria elimination and eradication prospects.

Main Methods:

• Historical literature review of malaria endemicity indices.
• Analysis of the evolution and application of these indices.
• Assessment of their applicability in the context of scaled-up malaria control and elimination efforts.

Main Results:

• Malaria endemicity indices have evolved significantly over time.
• Their institutionalization during past eradication programs shaped control strategies.
• Contemporary relevance is being re-evaluated amidst renewed focus on elimination.

Conclusions:

• Understanding the historical context of malaria indices is vital for effective current and future control.
• Indices need to be relevant to contemporary challenges of scaling up interventions and pursuing elimination.
• Re-evaluation of these tools is critical for the global community's malaria eradication goals.
