For Plasmodium falciparum (P. falciparum), atovaquone-proguanil, pyronaridine-artesunate, and mefloquine are recommended. This study monitored drug resistance genes in blood samples collected from patients with P. vivax (soldiers, relapsed, and imported) and P. falciparum (soldiers and civilians) between 2022 and 2025. In P. vivax, several Pvmdr-1 mutations showed high prevalence, with S515R, G698S, L845F, M908L, T958M, and F1076L observed in nearly all isolates, while T529 and E1233 mutation showed moderate prevalence. S513R, Y541C, A829V, and S1358 mutation were occasionally identified, all of which were imported or soldiers receiving prophylactic chemotherapy. Significant differences in mutation prevalence were identified among groups (p &lt; 0.05). However, no significant temporal trends were observed. In P. falciparum, the Y184F mutation in Pfmdr-1 was highly prevalent, and A675V mutation in PfK13 was detected only in soldiers. Group comparisons revealed significant differences (p &lt; 0.05), whereas temporal trends were not observed. Because drug resistance gene mutations can be closely linked to treatment, surveillance of drug resistance genes is expected to contribute to malaria eradication in the ROK through providing basic information related to treatment.<\/jats:p>","DOI":"10.3390\/pathogens15050508","type":"journal-article","created":{"date-parts":[[2026,5,8]],"date-time":"2026-05-08T20:11:13Z","timestamp":1778271073000},"page":"508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Molecular Surveillance of Plasmodium vivax and Plasmodium falciparum Drug Resistance Genes in the Republic of Korea: 2022\u20132025"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-6443-6456","authenticated-orcid":false,"given":"Haneul","family":"Jung","sequence":"first","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8146-7208","authenticated-orcid":false,"given":"Hyun-Il","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Zoonotic and Vector Borne Disease Control, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8821-0422","authenticated-orcid":false,"given":"Bora","family":"Ku","sequence":"additional","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esther","family":"Park","sequence":"additional","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3369-0063","authenticated-orcid":false,"given":"Myoung-Ro","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"},{"name":"Division of Laboratory Diagnosis and Analysis, Capital Regional Center for Disease Control and Prevention, Korea Disease Control and Prevention Agency, 131 Yeongjong Haeannam-ro 321beon-gil, Jung-gu, Incheon 22382, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5248-6995","authenticated-orcid":false,"given":"Jung-Won","family":"Ju","sequence":"additional","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1636-0639","authenticated-orcid":false,"given":"Hee-Il","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Vectors and Parasitic Diseases, Korea Disease Control and Prevention Agency, 187 Osongsaengmyeong 2-ro, Osong-eup, Heungdeok-gu, Cheongju 28159, Chungcheongbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,8]]},"reference":[{"key":"ref_1","first-page":"93","article-title":"Climate, environment and transmission of malaria","volume":"2","author":"Caputo","year":"2016","journal-title":"Infez.
