| studies on the transmission potential of surviving microfilaremias after basic control of filariasis. | after filariasis was basically controlled (the microfilarial rate was lower than 1%) in henan province in 1987, longitudinal observation of the disease has been carried out in all the province in order to study the regular pattern of growth and decline or the transmission potential of the disease. according to the distribution of filaria species and original microfilarial rate, 7 administrative villages in 7 counties were selected as surveillance sites. from 1988 to 1995, etiological and mosquit ... | 1997 | 9444011 |

| [assessment of intracutaneous test in longitudinal surveillance for lymphatic filariasis]. | in order to evaluate the usefulness of intracutaneous test (it) in longitudinal surveillance of filariasis, two administrative villages selected from queshan county, henan province of china, endemic for wuchereria bancrofti, were surveyed in 1982, 1983 and 1987 respectively, by it with antigen fpt derived from dirofilaria immitis. the result showed that the original level of it to antigen fpt in the population was consistent with the data of either etiological or entomological investigation befo ... | 1989 | 2699282 |
