The prevalence data as determined by microscopy and molecular methods were compared using chi-square tests.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Parasitaemia from these asymptomatic infections ranged from 40 to 3,520 parasites/µl of blood (geometric mean parasitaemia = 732 parasites/µl). The prevalence of asymptomatic P. falciparum carriage was 4.8% (10/209) and 13.9% (29/209) using microscopy and RT-PCR respectively. The overall prevalence of sub-microscopic infections in the total number of samples analysed was 9.1% (19/209) and 66% (19/29) of the asymptomatic infections. P. falciparum gametocytemia detected by microscopy was 1% (2/209) and 3.8% (8/209) by PCR.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">This is the first report of sub-microscopic asexual and gametocytes infections in the dry season in a seasonal malaria transmission area in Ghana. It has established that persistent latent malaria infections occur and that these could supply the source of parasites for the next transmission season. The findings highlight the presence of sub-microscopic infections and therefore the need for active case detection surveillance to eliminate "asymptomatic reservoir" parasites and consequently break the transmission of the disease in Ghana.</AbstractText><AbstractText Label="FUNDING" NlmCategory="BACKGROUND">Bill and Melinda Gates Foundation grant awarded to Noguchi Memorial Institute for Medical Research Postdoctoral and Postgraduate Training in Infectious Diseases Research (Global Health Grant # OPP52155); National Institutes of Health grant (NIH-NIAID RO1 # 1RO1AI099623) to MDW; European Developing Countries Clinical Trials Partnership (EDCTP)-West African Network of Excellence for Clinical Trials in TB, AIDS and Malaria (WANETAM) (Project code CB.07.41700.007).</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Atelu</LastName><ForeName>Geoffrey R</ForeName><Initials>GR</Initials><AffiliationInfo><Affiliation>Ghana Field Epidemiology and Laboratory Training Program, School of Public Health, College of Health Sciences, University of Ghana, Legon, Ghana.</Affiliation></AffiliationInfo><AffiliationInfo><Affiliation>Ghana Health Service, Accra, Ghana.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Duah</LastName><ForeName>Nancy O</ForeName><Initials>NO</Initials><AffiliationInfo><Affiliation>Epidemiology Department, Noguchi Memorial Institute for Medical Research, University of Ghana, P.
