| [epidemiological surveillance of filariasis after its being basically eradicated in shandong province]. | this paper reports the results of epidemiological surveillance in areas where filariasis has been basically eradicated and control measures no longer adopted in shandong province. a 3-year longitudinal surveillance in 18 villages in 5 counties and a cross-sectional survey in 13 villages of 4 counties were carried out. the results showed that the average microfilaria rate was further reduced from 0.28% and 0.15% in 1980 to 0.19% and 0.05% in 1986, decreased by 32.1% and 66.7% respectively. 34.2% ... | 1989 | 2670312 |
| [epidemiological survey on patients with advanced filariasis in shandong province with bancroftian filariasis basically eliminated]. | this paper reports on the incidence of advanced filariasis after basic elimination of bancroftian filariasis since 1983 in shandong province. investigation was carried out in a population of 166,776 between 1984 and 1988 in 252 villages of teng xian and other 5 counties/cities, the erstwhile highly endemic areas. a total of 1,038 filariasis patients were found with an average incidence of 0.6%. among them, 383 were with elephantiasis, 357 with chyluria and 298 with hydrocele. 902 cases (86.9%) w ... | 1990 | 2099251 |
