Recent advances in epidemiological field techniques in filariasis
1Department of Preventive Medicine and Biometrics, Uniformed Services University of the Health Services, Bethesda, MD 20814-4799.
Summary
Recent filariasis research offers new field techniques, including DNA probes for vector identification and mathematical models for disease prediction. Advances in diagnostics like antigen detection and quantitative blood counts improve infected person identification.
Area of Science:
- Epidemiology
- Parasitology
- Vector Biology
Background:
- Limited recent advances in filariasis epidemiological field techniques.
- Filariasis research has progressed in other areas with potential field applications.
Purpose of the Study:
- To summarize recent advances in filariasis research applicable to field epidemiology.
- Highlight new diagnostic and predictive tools for filariasis control.
Main Methods:
- Review of studies on vector-host interactions and DNA probes for vector speciation.
- Analysis of mathematical models for disease transmission dynamics.
- Evaluation of new diagnostic technologies including antigen detection and quantitative blood count.
Main Results:
- Development of species-specific larval identification in mosquito vectors.
- Proposed mathematical models for bancroftian filariasis transmission and microfilariae distribution.
- Advancements in antibody/antigen detection and quantitative blood count for diagnosing filariasis.
Conclusions:
- New techniques in vector identification and diagnostics significantly impact filariasis epidemiology.
- Mathematical models offer predictive capabilities for disease prevalence and control.
- Further research into ecdysteroid levels may aid lymphatic filariasis diagnosis.
