A trachoma survey has been made for 2.460 children of 3 primary schools in the T. area; 686 children are found positive and treated on a mass basis. The results obtained are as follows:1. The incidence is higher in household with limited space than in spacious household. It shows no difference between urban water works population and local well water population. It is much lower in household with private bath than that without it. It is also lower, in household with health insurance than that without it.2. Pre-treatment and post-treatment observations made comparatively over a period of 6 months reveal that early stage conjunctival signs (denoted by I. II. and III. types) are easily curable. Treatment at this early stage seems necessary. Some cases belonging to II and III types which are not treated on a mass basis have developed typical trachoma. Typical trachoma(denoted by IV∼X types)are found very difficult to cure.3. The new incidence is higher among the lower class students.
