However, afebrile Plasmodium falciparum malaria has rarely been reported in a returning traveler with no prior history of malaria infection. Here, we report an imported case of afebrile P. falciparum malaria infection from Tanzania in a returning traveler to the Republic of Korea, following an earlier COVID-19 infection without previous history of malaria infection. Our case suggests the hypothesis that severe symptoms of P. falciparum malaria infection might be prevented by cross- immunity from previous COVID-19 infection.<\/jats:p>","DOI":"10.3390\/tropicalmed7040059","type":"journal-article","created":{"date-parts":[[2022,4,10]],"date-time":"2022-04-10T06:02:54Z","timestamp":1649570574000},"page":"59","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["An Imported Case of Afebrile Plasmodium falciparum Malaria Infection from Tanzania in a Returning Traveler to the Republic of Korea following an Earlier COVID-19 Infection"],"prefix":"10.3390","volume":"7","author":[{"given":"Chaeryoung","family":"Lee","sequence":"first","affiliation":[{"name":"Division of Infectious Diseases, Department of Internal Medicine, CHA Bundang Medical Center, CHA University, Seongnam 13496, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung Kwan","family":"Hong","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Internal Medicine, CHA Bundang Medical Center, CHA University, Seongnam 13496, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6703-5804","authenticated-orcid":false,"given":"Jong Hun","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Internal Medicine, CHA Bundang Medical Center, CHA University, Seongnam 13496, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1560","DOI":"10.1086\/518173","article-title":"Fever in returned travelers: Results from the GeoSentinel Surveillance Network","volume":"44","author":"Wilson","year":"2007","journal-title":"Clin.
