An important parasitic infection among HIV infected patients is the cryptosporidiosis. Cryptosporidium
parvum is an intestinal parasitic protozoon that causes severe diarrhea and may lead to death in
immunocompromised hosts. In HIV infected cases with cryptosporidiasis, four main clinical syndromes were
identified: chronic diarrhea, choleralike disease, transient diarrhea, and relapsing illness. In this paper, the authors
presented the prevalence of cryptosporidiosis among Thai HIV-infected patients with diarrhea in comparison to the
previous noted prevalence in the past decade. The prevalence of among Thai HIV infected patients with diarrhea in
the previous decade is equal to 7.14 %. The present prevalence of among Thai HIV infected patients with diarrhea is
investigated with the same protocol. Overall 25 HIV infected cases could be detected giving the prevalence equal to
18.95 % (25/193). Of interest, although the HAART therapy is easily available in Thailand, at present the
prevalence of cryptosporidiosis is still very high in the HIV seropositive patients with diarrhea. Therefore, the
authors hereby propose that the wide distribution of HAART therapy did not affect the prevalence of
cyrptosporidiosis among HIV seropositive patients with diarrhea.
