Dear Sir,

Underdiagnosis of infection can be problematic in tropical medicine. The recent report on underdiagnosis of chikungunya virus infections is very interesting. [1] Reusken et al., [1] reported 6.5% of underdiagnosis of chikungunya virus infections among suspicious cases of dengue. Indeed, both dengue and chikungunya virus infections share common endemic areas and the clinical presentation of both infections are very similar. [2] The difficulty in diagnosis of infections among travelers returning from endemic areas to Europe is confirmed and the concern of practitioner is needed. [1],[2],[3] However, the same problem still exists in the endemic area. [4] Mainly, dengue infection is usually presumptive diagnosis and the missed definitive diagnosis by serological confirmation is usually practiced. [4] The use of proper diagnostic test to verify the infection among the suspicious cases is important and should be included in the routine clinical practice guideline.
