In addition, the incidence rate is the forth-highest rate in southern Thailand and the highest rate in the 12th health zone while

From these points, the evaluation of Leptospirosis surveillance in Phatthalung Hospital has been explored to study the procedure of reporting of diseases and to study the qualitative and quantitative characteristics in order to improve the Leptospirosis surveillance system to be more efficient.

For age variable from R 506 system, it was found that the median age is 48 years (IQR 30-59), which corresponds to medical record information of 49.5 years (IQR 33.3-58.8). Timeliness is 95.65% (22 records). For qualitative information, age and habitat (subdistrict and district) variables are completely correct with 100% while variables of gender, type, date of incidence and career are 95.65%, 91.30%, 78.26%, and 73.91%, respectively. The qualitative characteristic result was found that this system is acceptable, easy, flexible, and stable. Knowhow and information are practical and beneficial.
