[Analysis and efficiency-evaluation of case-finding among symptomatic suspects in rural area by smear microscopy]

216,307 suspects were discovered within the period from Oct. 1st, 1987 to Spt. 30th, 1988 in rural area of 26 counties. The suspect rate was demonstrated to be 2.2%; 182,917 persons accepted smear microscopy among suspects and the smear microscopy rate was 84.6%; 7,046 smear positive cases were detected and the smear positive rate was confirmed to be 3.95% among smear-accepted suspects. Smear microscopy among symptomatic suspects in rural area for infectious case-finding is recommended, because this method costs low, and is more effective and practical.
