Overview
Worldwide, the prevalence of mastitis ranges from a low of 1000 per 100,000 persons to a high of 10000 per 100,000 persons with an average prevalence of 4700 per 100,000 persons.[1] Worldwide, the incidence of Puerperal mastitis ranges from a low of 2900 per 100,000 persons to a high of 9500 per 100,000 persons with an average incidence of 6200 per 100,000 delieveries within the first seven weeks after delivery.[2] [3] [4]. Out of this, the incidence of those with mastitis needing hospitalization is 93 per 100,000 persons.[5]. The percentage of those with mastitis who develop breast abscess varies from 3% to 11%.[6] Mastitis commonly affects breastfeeding mothers between the ages of 21 to 35 with the highest occurrence between 30 to 34 years even when parity and full-time employment are controlled.[7] However, there is no difference between mastitis and breast abscess groups regarding age.[8] Women are more commonly affected with mastitis than men. There is no racial predilection to mastitis. Georgraphically the incidence of mastitis is higher in developing countries. [7]
