<explanation>
yue:喺一個地方持續出現嘅病症（量詞：個）
eng:endemic disease
<eg>
yue:要喺一個地方做醫生，首先要對嗰笪地方嘅風土病有基本嘅認識，例如香港人好常見嘅蠶豆症，喺英國畢業嘅醫生，就未必識嘞。 (jiu3 hai2 jat1 go3 dei6 fong1 zou6 ji1 sang1, sau2 sin1 jiu3 deoi3 go2 daat3 dei6 fong1 ge3 fung1 tou2 beng6 jau5 gei1 bun2 ge3 jing6 sik1, lai6 jyu4 hoeng1 gong2 jan4 hou2 soeng4 gin3 ge3 caam4 dau2 zing3, hai2 jing1 gwok3 bat1 jip6 ge3 ji1 sang1, zau6 mei6 bit1 sik1 laak3.)
eng:To be a doctor in a locality, one must first know the endemic diseases there. For example, favism, though rather common in Hong Kong, is not common knowledge among UK graduates.
