Postpartum Infections: Signs, Types, Treatment and Prevention

• Any fever of 38°C (100.4°F) or above in the six weeks after birth is never "just healing"—it always needs same-day medical review.
• Endometritis (womb-lining infection) is the most common postpartum infection and is 5–10 times more likely after a caesarean than a vaginal birth.
• Watch your wounds, your lochia (vaginal bleeding) and your breasts: spreading redness, foul-smelling discharge, increasing pain after day 3, or a hot painful breast lump are the key red flags.
• Most postpartum infections are treated with antibiotics that are safe to take while breastfeeding—do not stop feeding your baby.
• Simple steps prevent most infections: hand hygiene, frequent pad changes, gentle daily bathing, good wound care and a correct breastfeeding latch.
• In an emergency, call free ambulance services 102 or 108. Trust your instincts—if something feels seriously wrong, it usually is.

Several things come together in the days after childbirth to make infection both more likely and more serious. The uterus has a raw inner surface where the placenta was attached—essentially a large open wound that takes 2 to 6 weeks to fully heal over. The cervix stays slightly open for the first few days, allowing bacteria from the vagina to travel upwards. Perineal tears, episiotomies and caesarean incisions are direct entry points for skin and gut bacteria.

Your immune system is also slightly dialled down. Pregnancy and the early postpartum period naturally suppress immunity a little (this protected your baby from rejection during pregnancy). Hormonal changes and a sluggish bladder make urinary infections easier to develop, and cracked nipples let bacteria into breast tissue.

India-specific factors add to the risk. Anaemia in pregnancy affects more than half of Indian women per ICMR–NFHS-5 data and weakens the immune response. Sleep deprivation, stress and poor nutrition lower defences further, and in some settings prolonged labour, repeated vaginal examinations and unhygienic delivery practices add danger. The National Health Mission's push for clean, respectful, institutional delivery—through programmes like Janani Suraksha Yojana—has steadily reduced maternal sepsis deaths over the last decade. But most infections show up after discharge, so staying alert at home matters most.

• Fever above 38°C with chills
• Lower abdominal or pelvic pain and uterine tenderness
• Foul-smelling vaginal discharge (lochia)
• Feeling generally unwell, more so after a caesarean

A caesarean wound becomes infected in roughly 3 to 15 per cent of women, with the rate depending on hospital infection-control practices and individual risk factors. Higher risk comes with obesity, diabetes, smoking, a long labour or long rupture of membranes before the C-section, an emergency rather than planned operation, anaemia and chorioamnionitis (an infection already present in labour).

Most superficial infections appear between days 4 and 7. Look for redness spreading beyond the incision, swelling, warmth, increasing pain, discharge of pus or blood, and sometimes a low-grade fever. Deeper infections involving the fascia or muscle are more serious, with high fever, severe pain and sometimes the wound starting to separate.

Prevention measures, used in FOGSI-accredited Indian hospitals, include a single dose of preventive IV antibiotic (cefazolin 2 g) within 60 minutes before the skin incision, chlorhexidine skin preparation, clipping rather than shaving hair, keeping you warm during surgery, and double-gloving for higher-BMI women.

Treatment of a superficial infection means draining any collection of pus, removing dead tissue, oral antibiotics such as amoxicillin-clavulanate or cefuroxime for 5 to 7 days, and dressings changed every 1 to 2 days. Deep infection or the rare but life-threatening necrotising fasciitis needs urgent surgical exploration and IV antibiotics. At home during your week-by-week C-section recovery, watch for spreading redness, increasing pain after day 3, fever or wound discharge—these need same-day evaluation.

Perineal wounds—from a spontaneous tear or a planned episiotomy—become infected in about 1 to 2 per cent of vaginal births. Risk is higher with third- or fourth-degree tears, retained stitches, a blood collection (haematoma), poor hygiene, contamination of the wound with stool, and conditions like diabetes.

Infection usually shows up within 3 to 7 days. The clearest warning sign is pain that increases instead of easing, along with wound separation, foul-smelling discharge, redness, swelling, fever, and sometimes difficulty passing urine or stool. An obstetrician's examination decides the depth and extent of infection.

Mild cases respond to cleansing with sterile saline, sitz baths twice daily, broad-spectrum oral antibiotics (amoxicillin-clavulanate, or cefuroxime plus metronidazole) and pain relief. Deeper infections may need the wound to be opened and cleaned, re-stitched later, or in stubborn cases repaired by a urogynaecologist. Necrotising fasciitis of the perineum is rare but can be rapidly fatal if missed—excruciating pain out of proportion to what is visible, fast-spreading dusky skin, crackling under the skin (gas) and signs of sepsis make it a surgical emergency.

For day-to-day home care, see our detailed guides to episiotomy and perineal tear healing and caring for perineal stitches. The basics: rinse with a peri-bottle after every toilet visit, change pads often, take sitz baths, pat dry gently, wear loose cotton underwear, and keep scented soaps and oils off the wound.

• Burning or stinging when passing urine
• Going more often, with sudden urgency
• Cloudy, dark or foul-smelling urine
• Lower abdominal, pelvic or back pain
• Fever, flank pain and vomiting (suggests a kidney infection—seek care promptly)

Mastitis—inflammation of breast tissue—affects about 1 in 5 breastfeeding mothers, usually in the first 6 weeks. It shows up as a hot, red, painful, wedge-shaped area of one breast, often with fever above 38°C, chills, body aches and flu-like symptoms.

Common causes are milk stasis (a breast not draining well), cracked or sore nipples that let bacteria (usually Staphylococcus aureus) in, tight clothing and stress. The Academy of Breastfeeding Medicine's 2022 mastitis spectrum guidelines recommend a gentler approach than in the past: keep breastfeeding normally (aggressive pumping makes inflammation worse), use ice for swelling, take ibuprofen for inflammation, consider sunflower lecithin for narrowed ducts, and use antibiotics only when fever persists beyond 24 hours, when there is a clear bacterial source, or when symptoms are worsening.

When antibiotics are needed, the usual choices are dicloxacillin 500 mg four times daily, flucloxacillin 500 mg four times daily, or cefalexin—all safe with breastfeeding—for 10 to 14 days. If there is no improvement in 48 to 72 hours, an ultrasound checks for an abscess, which needs needle aspiration or surgical drainage.

The most important message: do not stop breastfeeding during mastitis—continued feeding helps the breast drain and speeds recovery. Lactation consultants (IBCLCs) at hospitals like Apollo, Cloudnine and Fortis, and through BPNI, can help with latch and prevention. Our deep dive on mastitis and blocked ducts covers this in detail.

Septic pelvic thrombophlebitis is rare but serious: infection in the pelvis triggers clots in the pelvic veins, causing a fever that simply will not settle despite correct antibiotics for what looked like ordinary endometritis. Diagnosis is clinical (persistent unexplained fever) plus a CT or MRI scan. Treatment is IV antibiotics plus blood-thinning with heparin for 7 to 14 days.

Other serious infections to know about include toxic shock syndrome from Group A Streptococcus—rapid onset, high fever, rash, low blood pressure and multi-organ failure, needing urgent ICU care (see our guide to recognising postpartum toxic shock syndrome)—and chorioamnionitis that carries on into postpartum sepsis. Necrotising fasciitis of perineal or caesarean wounds is rare but fatal without urgent surgery.

Septic shock is the final common pathway of severe infection—low blood pressure, racing heart, confusion and failing organs—and demands immediate IV fluids, broad-spectrum antibiotics within an hour, and "source control" (draining or removing the infected tissue). Indian critical-care obstetric units follow Surviving Sepsis Campaign bundles adapted to local resources.

The single most important factor in survival is early recognition. Never dismiss a persistent fever, worsening pain or simply "not feeling right" in the postpartum period—it is also wise to learn the difference between infection and other emergencies like late-onset postpartum preeclampsia and eclampsia.

Preventing a puerperal infection is far easier than treating one, and most steps are simple.

Before birth: treat anaemia aggressively (the Anaemia Mukt Bharat programme provides free iron–folic acid), screen for and treat symptomless urine infections and bacterial vaginosis, clear any vaginal infection before delivery, and keep diabetes well controlled.

During labour and delivery: keep vaginal examinations to a minimum, maintain sterile technique, give preventive antibiotics for caesareans, repair perineal wounds carefully, and use active management of the third stage of labour to reduce the chance of retained tissue and heavy bleeding (see postpartum bleeding and lochia).

In the early postpartum days: get up and move early, wash your hands before touching your perineum or baby, change pads every 3 to 4 hours, shower daily with clean water, rinse the perineum after each toilet visit, and care for any incision properly.

Some Indian confinement customs need gentle adapting. Daily gentle bathing is hygienic and helpful—avoiding it for 40 days lets bacteria thrive on wounds and skin. Abdominal binders are fine if loose and only over healed skin. Rest is good, but lying immobile for weeks is harmful—light movement lowers infection and clot risk.

Breastfeeding hygiene: wash hands before feeds, treat sore nipples early, get a good latch to prevent cracks, and deal with blocked ducts quickly. Finally, attend your follow-up visits—FOGSI recommends checks at around 24 hours, 7 days and 6 weeks, with the six-week postpartum checkup being a key milestone for catching problems.
