TAPIA-ROMERO, Raquel et al. Parasitological transition: Experience in a third-level pediatric hospital (1990-2010). Bol. Med. Hosp. Infant. Mex. [online]. 2015, vol.72, n.3, pp.174-180. ISSN 1665-1146.


In recent years, the main reason for parasitological diagnosis was suspicion of a parasitic etiology. Currently, diagnosis and consultation are associated with co-morbidity with a hemato-oncological, autoimmune, immunodeficiency or post-transplant condition.


Results collected from the Parasitology Laboratory of the Hospital Infantil de Mexico Federico Gómez from January 1990 to December 2010 were analyzed to determine the frequency and distribution of parasites and commensals per year and decade.


There were 211,600 samples analyzed with a statistical media of 10,100 and a standard deviation of 3,500 samples. Percentage of observations for parasitic structures as well as commensals was 37.73% according to Pearson Chi square with a significant difference among percentages between decades (p < 0.0001).


Behavioral tendency of intestinal parasitosis during the last two decades shows a change in frequency and genera from the agents that were reported at this pediatric health care level. The processing of epidemiologic information is important in order to determine the response of the parasitosis and its variations over time.
