Detection of the infection

Today we brought Png Png to PD Sim for consultation as Png Png did not pass motion since Wed. PD Sim spotted some purplish spots on Png Png and asked me if they were there when he was discharged. Png Png had red spots all over his face and body and I thought the purplish spots were there. PD Sim said ok then leave it as it is but he felt uneasy
