Summary
Insecticide-treated nets (ITNs) are crucial for malaria elimination in Southeast Asia. However, consistent ITN use varies significantly, with geographic region and socioeconomic status being key factors influencing non-use.
Area of Science:
- Public Health
- Epidemiology
- Vector-borne Diseases
Background:
- Malaria poses a significant public health challenge in Southeast Asia.
- Eliminating malaria relies on widespread use of insecticide-treated nets (ITNs).
- Limited regional data exists on ITN utilization patterns.
Purpose of the Study:
- To systematically review and meta-analyze ITN utilization in Southeast Asia.
- To identify factors associated with ITN non-use.
- To inform malaria control strategies in the region.
Main Methods:
- Systematic review and meta-analysis following PRISMA guidelines.
- Searched PubMed, Web of Science, and ScienceDirect databases.
- Included 28 studies (20 for quantitative analysis) involving 14,556 households and 122,258 individuals.
Main Results:
- A notable gap exists between ITN ownership/access and actual usage.
- Geographic region (coastal vs. delta) and socioeconomic status (poorest vs. richest) significantly predicted ITN non-use.
- Substantial heterogeneity across studies highlights setting-specific variations.
Conclusions:
- Contextual factors like geography and socioeconomic status are stronger determinants of ITN non-use than demographic factors alone.
- Area-specific risk assessments are vital for optimizing malaria prevention interventions.
- Targeted strategies to improve consistent ITN utilization are essential for malaria elimination in Southeast Asia.

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
