In the case of newborn babies, it may cause adverse effects like growth restriction, an abnormally small head, enlargement of the liver and spleen, inflammation of the liver, anemia, and calcium deposits in the brain.

Neonatal herpes

It present in the form of blisters on the face and mouth of a newborn may be due to the transmission of genital herpes present in the woman.


In HIV, there is an impact on low birth weight and swelling in the liver and spleen during birth.


It may spread from mother to baby during pregnancy and is connected with preterm birth and in some cases death shortly after birth. Untreated infants who survive are prone to have problems in organs like in brain, eyes, ears, heart, skin, teeth, and bones.

The different tests important for the infection diagnosis are as follows:

Complete blood count (CBC)

A CBC estimates the number of different cells that are present in the blood. The number of white blood cells may indicate the disease-fighting mechanism in your blood.

Polymerase chain reaction (PCR)

They are extremely reliable, quick blood, mucus, or saliva tests used to diagnose some infectious diseases and genetic changes.

Urine culture

This test is supposed to be done to find out if there may be any bacteria present in urine that could point to a UTI.

Prenatal diagnosis (PND)

One of the PND procedures involves Amniocentesis which is done by removing a small amount of fluid for testing from the womb. Sometimes amniocentesis is done to ascertain if the baby has an infection or other illness. Usually, genetic amniocentesis is done around 15-20 weeks of gestation. Amniocentesis procedure before 15 weeks of pregnancy may involve a high risk of complications. Your healthcare professional may not incline towards amniocentesis if you are suffering from HIV/AIDS, hepatitis B, or hepatitis C infections as they can be passed on to your baby during the procedure.

There are routine USG scans done usually around 12 and 20 weeks to check for proper development of the fetus and surrounding structures. Additionally, sonography can be done in case of bleeding from the vagina or abdominal pain in the initial stages of pregnancy to rule out any other conditions or signs of miscarriage.
