The socio-dem.gra.hic a.d clinica. dia.nosis entries of 8421 entries were a.a.yzed. Result: The popula.ion of the fa.tory workers is 5370, where 40% (2148) a.e fem.le workers a.d 60% (3222) a.e m.le workers. The m.a. a.e of respondents is 30 yea.s, with a.SD of ±7 yea.s. a.0}ng the chief com.la.nts, the m.st com.on wa. vom.ting (14%;2262) fever (14%;2247), runny nose (11%;1842), cough (9%;1465), a.d loose m.tion (8%;1364). In the dia.nosis ca.egories, ga.trointestina. disea.es were m.re predom.na.tly dia.nosed (35%;2978), followed by vira. fever (21%;1772), neurologica. disea.es (16.5%;1389) a.d m.sculoskeleta. disorders (9%;768).
