Neonatal Sepsis

Neonatal sepsis is a serious bacterial infection that can affect newborns. It occurs when bacteria enter the baby’s bloodstream and cause an inflammatory response in the body. Left untreated, neonatal sepsis can be fatal. Early diagnosis and treatment of this condition are critical to saving the life of an infant. Risk factors include prematurity, low birth weight, prolonged rupture of membranes, and maternal infection during labor. Fortunately, with advances in medical care and technology, many cases of neonatal sepsis can be successfully treated.

What is neonatal sepsis?

Neonatal sepsis is a serious infection that affects newborn babies. It occurs when bacteria or other germs enter the baby's bloodstream, often as a result of an infection in another part of the body. Symptoms may include fever, poor feeding, difficulty breathing, lethargy, and jaundice. If left untreated, it can be fatal. Treatment typically involves antibiotics and supportive care such as fluids and oxygen. Early diagnosis and aggressive treatment are essential for preventing long-term complications or death.

What are the different types of neonatal sepsis?

There are various types of neonatal sepsis. Early-onset sepsis occurs during the first week of life and is usually caused by bacteria that a newborn baby picks up in the birth canal. Late-onset sepsis develops after the first week, often due to an infection in the environment. Congenital sepsis is caused by bacteria or viruses that a baby has been exposed to while still in the womb. Another type is meningitis-associated sepsis, which can occur when bacteria enter a baby's bloodstream and cause inflammation of the meninges. Lastly, nosocomial sepsis is an infection acquired during hospitalization.

What are the causes of neonatal sepsis?

Neonatal sepsis is caused by bacteria entering the bloodstream through the umbilical cord, placenta, or vagina during childbirth. Bacteria can also enter if a baby has an infection in their skin, lungs, urinary tract, or digestive system, or from a contaminated device such as a catheter. Premature babies are most at risk for sepsis because their immune systems are not fully developed yet. Some cases of neonatal sepsis can be prevented with antibiotics given to mothers during labor and delivery.

What are the symptoms of neonatal sepsis?

Neonatal sepsis can cause several symptoms in newborns, including fever, irritability, vomiting, poor feeding, lethargy, and rapid breathing. Other signs include a weak cry or a lack of responsiveness to touch or sound. In some cases, there may be a pale or bluish colour to the skin and jaundice. Severe infections can cause seizures, low blood sugar levels, and difficulty maintaining body temperature. Some babies may also develop an infection in their bloodstream that causes swelling in their arms or legs.

When should you see a doctor for neonatal sepsis?

If a baby is displaying symptoms of neonatal sepsis, such as fever, irritability, lethargy, difficulty feeding, or rapid breathing, a doctor should be seen immediately. Parents should also monitor for other signs such as vomiting and diarrhoea, apnea or bradycardia, mottling of the skin or redness in areas on the body, and an abnormal heart rate. In all cases where any of these symptoms are observed, medical attention should be sought right away.


Sepsis is a serious condition that can affect newborns, leading to long-term health issues or death. Early detection and treatment are essential for the best possible outcomes. While neonatal sepsis cannot always be prevented, it is important for parents of newborns to be aware of its symptoms and to seek prompt medical attention if they suspect their infant may have contracted it. With early recognition and appropriate care, neonatal sepsis can be managed effectively, and babies can go on to lead healthy, happy lives.

1. How is neonatal sepsis diagnosed?

Neonatal sepsis is usually diagnosed using blood tests to detect bacterial infection and assess organ function.

2. What are the possible complications associated with neonatal sepsis?

Complications associated with neonatal sepsis can include meningitis, pneumonia, hearing loss, developmental delays, and death in severe cases.

3. How can neonatal sepsis be prevented?

Neonatal sepsis can be prevented by washing hands before handling newborns, avoiding unnecessary medical procedures on the baby during labor and delivery, and ensuring that those caring for the baby have up-to-date vaccinations against certain bacteria that can cause sepsis in newborns.

4. Are some babies more at risk for neonatal sepsis?

Babies born prematurely and those with a weakened immune system are more at risk for developing neonatal sepsis.
