Contribution of dengue fever to the burden of acute febrile illnesses in Papua New Guinea: an age-specific prospective study (Publications)
were enrolled, and 317 patients with a negative rapid diagnostic test (RDT) for malaria were tested for dengue. Malaria was confirmed in 52% (301/578, 95% confidence interval [CI] = 48-56%), DF was diagnosed [...] Abstract. Malaria is a major contributor to the burden of febrile illnesses in Papua New Guinea (PNG). Dengue fever (DF) is likely to contribute; however, its epidemiology in PNG is poorly understood. [...] diagnosed in 8% (46/578, 95% CI = 6-10%), and 40% (95% CI = 36-44%) had neither...
A multiplex qPCR approach for detection of <em>pfhrp2 </em>and <em>pfhrp3</em> gene deletions in multiple strain infections of <em>Plasmodium... (Publications)
The rapid and accurate diagnosis of Plasmodium falciparum malaria infection is an essential factor in malaria control. Currently, malaria diagnosis in the field depends heavily on using rapid diagnostic [...] blood. P. falciparum strains lacking PfHRP2, due to pfhrp2 gene deletions, are an emerging threat to malaria control programs. The novel assay described here, named qHRP2/3-del, is well suited for high-throughput

LLIN distribution were also examined. METHODS: Dynamic simulations of malaria in humans and mosquitoes were run on the OpenMalaria platform, using stochastic individual-based simulation models. LLINs were [...] BACKGROUND: Stagnating funds for malaria control have spurred interest in the question of how to sustain the gains of recent successes with long-lasting insecticidal nets (LLINs) and improved case management [...] management (CM).

In general, the transcript [...] abundances of var group A and B genes were higher for children with clinical malaria than for children with asymptomatic infections. The var group C and var1-like transcript abundances were similar between

Immunoglobulin G subclass-specific responses against <em>Plasmodium falciparum</em> merozoite antigens are associated with control of parasitemia and... (Publications)
merozoite antigens play a role in protection from malaria, although the precise targets and mechanisms mediating immunity remain unclear. Different malaria antigens induce distinct immunoglobulin G (IgG) [...] (IgG) subclass responses, but the importance of different responses in protective immunity from malaria is not known and the factors determining subclass responses in vivo are poorly understood. We examined [...] AMA-1-specific IgG3 and MSP1-19-specific IgG1 were strongly predictive of a...
Aetiology of fever in returning travelers and migrants: a systematic review and meta-analysis (Publications)
openia and hyperbilirubinemia were respectively 5-14, 3-11 and 5-7 times more likely in malaria than non-malaria patients. High variability of results between studies reflects heterogeneity in study design [...] investigations performed, and diseases included. CONCLUSION: Malaria accounted for one fifth of febrile cases, highlighting the importance of rapid malaria testing in febrile returning travelers, followed by other [...] met criteria for data extraction. Tropical infections accounted for...
