Whole genome sequencing is valuable for identifying such genomic changes and antimalarial drug resistance. However, sequencing submicroscopic and asymptomatic cases presents challenges due to their low parasite densities and relative abundance of human DNA. Selective whole genome amplification (SWGA) is a method that employs oligonucleotide primers and\n                      <jats:italic>phi29<\/jats:italic>\n                      DNA polymerase to specifically amplify\n                      <jats:italic>Plasmodium<\/jats:italic>\n                      DNA. SWGA has proven effective in generating increased genome coverage for various\n                      <jats:italic>Plasmodium<\/jats:italic>\n                      species. Despite its promise, current SWGA protocols have proven unsuitable in routine clinical settings. This study optimizes the SWGA protocol to improve amplification efficiency and simplify processing of clinical samples.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Thirteen\n                      <jats:italic>P. falciparum<\/jats:italic>\n                      clinical whole blood samples from returning travellers underwent SWGA with varying incubation durations of 2, 8, and 16\u00a0h. Using a newly developed SWGA protocol, three samples were additionally incubated at 3\u00a0h with EquiPhi29\u2122 DNA Polymerase, a newer version of the\n                      <jats:italic>phi29<\/jats:italic>\n                      enzyme. Effectiveness of the varying conditions were compared by their amplification and sequencing yield, parasite DNA recovery, genome coverage and coverage depth. After read number normalization through random selection with\n                      <jats:italic>rasusa<\/jats:italic>\n                      , pairwise SNP comparison was also performed to ensure variant calling by\n                      <jats:italic>freebayes<\/jats:italic>\n                      was unaffected by the changes in condition. Pairwise agreement was tested by Cohen\u2019s Kappa. Drug resistance profiles for each sample were generated with\n                      <jats:italic>Malaria-Profiler<\/jats:italic>\n                      to further verify these findings.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The results demonstrate that there were comparable amplification and sequencing yields between the 8 and 16\u00a0h SWGA durations. These durations also showed significant results similarities in variant calling with up to\u2009&gt;\u200990% SNP concordance. Moreover, using the newer developed SWGA protocol, sequencing yields and genome coverage were significantly enhanced, achieving over 63%\n                      <jats:italic>P. falciparum<\/jats:italic>\n                      genome coverage in just three hours processing prior to sequencing.
