Nan Province, located in northern Thailand, is hyperendemic for parasite infections; the helminthic infection rate in 1,010 schoolchildren was 60.0% in 2001. Mass anthelmintic chemotherapy has been conducted with schoolchildren, and selective treatment has been given to people in the community, from 2002. The modified cellophane thick smear method was used to examine the prevalence and intensity of helminth infections in schoolchildren and community people once a year during the period 2002-2004. The prevalence of helminth infections decreased slowly from 60.0 to 40.3% in schoolchildren and from 70.8 to 60.0% in the older age population. Three parasite species were common: hookworm, Ascaris and Haplorchis, an intestinal trematode. Hookworm presented throughout the whole district. Ascaris infection occurred at high rates in some villages, while in some villages none was found. The villages where Ascaris infection was nil had high rates of Haplorchis infection, and vice versa. Most hookworm and Trichuris infections were of light intensity. Heavy intensity infection was found in 12.8-18.1% of Ascaris cases examined. Parasite infection rates in Chaloem Phra Kiat District can be classified as low prevalence.

ACIPAC has made an effort to promote the concept of the school-based approach to malaria and STH control, mainly through human resource development, which could be eventually extended to any other health promotion program. Implementation of SSPP resulted in the establishment of national policies on parasite control and/or school health in some partner countries. It also provides a good opportunity for the formulation of partnerships among health and education sectors and international partners, although it did cause some problems concerning the enrollment of persons of authority from partner countries, and the staff of JICA resident offices as well. As described in the Joint Evaluation Report, ACIPAC is expected to further contribute to human resource development and to strengthening human resource and information networking at regional and global levels.

Foram realizados exames parasitológicos em 485 habitantes de quatro vilarejos da cidade de Säo Lourenço da Mata, distante 25 Km à noroeste de Recife-PE, Brasil, no período de julho à dezembro de 1989. Aproximadamente 99,6% dos examinados mostraram-se infectados com pelo menos uma espécie de parasita intestinal. Observou-se ainda uma alta prevalência de Shistosoma mansoni (82,1%), ancilostomídeos (80,2%), Trichuris trichiura (69,9%), Ascaris lumbricoides (61,9%) e Entamoeba coli36,7%). A cultura de larvas de ancilostomídeos nas fezes - método de Harada - revelou que Necator americanus (84,4%) é a espécie mais comum nesta regiäo seguida pelo Strongyloides stercoralis. Foram ainda realizados testes sorológicos imunodifusäo em gel (GDP) e enzima imunoensaio (ELISA) - em 334 soros, para o diagnóstico de amebíase, todavia apenas 24 (7,2%) dos soros apresentaram positivdade no teste de ELISA e nenhuma positividade foi encontrada nos mesmos soros testados pelo GDP

Exames parasitológicos foram realizados em 187 pacientes do Hospital do IMIP e 464 habitantes de vários vilarejos no município do Cabo, 50 Km à sudeste de Recife, durante os meses de abril a agosto. Aproximadamente 71% dos pacientes examinados do IMIP e 92% dos examinados do Cabo apresentavam-se infectados com, no mínimo, uma espécie de parasita intestinal. Houve uma diferença mínima na taxa de prevalência de trichiura entre as duas áreas, entretanto a prevalência de Ascaris lumbricoides, família Ancylostomidae, Strongyloides stercoralis, Schistosoma mansoni e Entamoeba histolytica foi maior entre os habitantes do Cabo. Somente a Giardia lamblia apresentou uma taxa de prevalência maior nos pacientes do IMIP. O cultivo em tubo de ensaio revelou que a prevalência do Necator americanus em relaçäo a do Ancylostoma duodenale era muito maior em ambas as áreas e que a do S. stercoralis entre os pacientes do IMIP e dos habitantes do Cabo era, respectivamente, 4.5% e 9.6%. A amebíase foi verificada através de exames sorológicos, imunodifusäo em gel (GDP) e enzima imunoensaio (ELISA), usando como antígeno extrato bruto preparado a partir dos trofozoitos de E. histolytica (cepa HM-1: IMSS), realizados em 615 soros, onde nenhuma reaçäo positiva aparente foi observada através da imunodifusäo, contudo foram observados resultados positivos em 32 dos 615 casos através da enzima imunoensaio
