One of the major challenges in assessing S. stercoralis prevalence is the lack of wellconducted studies in suspected endemic areas
Those techniques, such as Harada-Mori filter paper strip, Baerman concentration technique, or Koga agar plate culture, are both time and resource consuming, and newer enzyme-linked immunosorbent assay (ELISA)–based serological tests are only available in some settings, limiting the diagnosis in endemic areas [3]
Summary
National Referral Centre for Tropical Diseases, Infectious Diseases Department, Ramon y Cajal Hospital, IRYCIS, Madrid, Spain. Spain seems to be considered an endemic country for strongyloidiasis, as shown in two recent reviews on the global epidemiology of this disease that were both published within one year in PLOS Neglected Tropical Diseases [2, 7]. Schär et al found five articles describing the prevalence of S. stercoralis in Spain since 1989; within these articles, three studies focused on immigrants and refugees, and the other two studies were performed in recently arrived populations and might reflect the rates from their countries of origin.
