Optimizing malarial epidemiological studies in areas of low transmission by Amerasinghe, Priyanie H., Alifrangis, M., Hoek, Wim van der, Wirtz, R.A., Amerasinghe, Felix P., Konradsen, Flemming

“…This study suggests that in low-transmission areas, such as Sri Lanka, smaller sample sizes can be used for epidemiological research studies using PCR instead of microscopy to estimate parasite prevalence. This efficiency gain has to be weighed against the higher cost and complexity of the PCR. …”
