Acute mastitis

Acute mastitis is an acute purulent infection of the breast. It is an inflammation of the connective tissues in and around the mammary ducts. Abscesses often form in a short period of time, and are mostly caused by S. aureus or streptococcus invasion along the lymphatic vessels. It occurs more frequently in postpartum breastfeeding women, especially in primipara. Germs usually invade from nipple breaks or clefts, and can also invade directly to cause infection. It has been reported in the literature that 50% of primiparas with acute mastitis are affected, and the ratio of primiparas to menstruals is 2.4: 1. It can occur at any time during lactation, but it is most common at 3-4 weeks postpartum, so it is also called puerperal mastitis.
