A case of knowlesi malaria is described in a Swedish man, who became ill after returning from a short visit to Malaysian Borneo in October 2006. His <jats:italic>P. knowlesi<\/jats:italic> infection was not detected using a rapid diagnostic test for malaria, but was confirmed by PCR and molecular characterization. He responded rapidly to treatment with mefloquine. Evaluation of rapid diagnostic kits with further samples from knowlesi malaria patients are necessary, since early identification and appropriate anti-malarial treatment of suspected cases are essential due to the rapid growth and potentially life-threatening nature of <jats:italic>P. knowlesi<\/jats:italic>. Physicians should be aware that knowlesi infection is an important differential diagnosis in febrile travellers, with a recent travel history to forested areas in south-east Asia, including short-term travellers who tested negative with rapid diagnostic tests.<\/jats:p>","DOI":"10.1186\/1475-2875-8-15","type":"journal-article","created":{"date-parts":[[2009,1,16]],"date-time":"2009-01-16T07:13:28Z","timestamp":1232090008000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":102,"title":["Swedish traveller with Plasmodium knowlesi malaria after visiting Malaysian Borneo"],"prefix":"10.1186","volume":"8","author":[{"given":"Ulf","family":"Bronner","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul CS","family":"Divis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"F\u00e4rnert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balbir","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2009,1,16]]},"reference":[{"key":"764_CR1","volume-title":"Malaria parasites and other haemosporidia","author":"PCC Garnham","year":"1966","unstructured":"Garnham PCC: Malaria parasites and other haemosporidia. 1966, Oxford: Blackwell Scientific Publications"},{"key":"764_CR2","volume-title":"The primate malarias","author":"RG Coatney","year":"1971","unstructured":"Coatney RG, Collins WE, Warren McW, Contacos PG: The primate malarias. 1971, Washington: US Government Printing Office"},{"key":"764_CR3","doi-asserted-by":"publisher","first-page":"1017","DOI":"10.1016\/S0140-6736(04)15836-4","volume":"363","author":"B Singh","year":"2004","unstructured":"Singh B, Sung LK, Matusop A, Radhakrishnan A, Shamsul SSG, Cox-Singh J, Thomas AW, Conway D: A large focus of naturally acquired Plasmodium knowlesi infections in human beings.
