What is impetigo during pregnancy?
Impetigo is a condition in which Streptococcus or Staphylococcus bacteria gets inside the skin through either of two mechanisms. Either there is a cut or other injury through which the bacteria enter, or the skin is damaged from a condition, such as insect bites, scabies, or head lice, also providing the bacteria with an entrance. The infection is very contagious and causes sores that can be itchy with blisters. There are two main subtypes of impetigo. Comprising 70 percent of cases, nonbullous impetigo (also called impetigo contagiosa), features honey-colored crusts on the extremities and face. This type of impetigo is caused by either Streptococcus pyogenes or Staphylococcus aureus. S. aureus also causes the other subtype, known as bullous impetigo. Accounting for 30 percent of impetigo cases, bullous impetigo features flaccid bullae and is characterized by droopy blisters generally in locations where skin rubs together, such as in your armpits.
How common is impetigo during pregnancy?
Impetigo affects mostly children, accounting for approximately 10 percent of pediatric skin problems. However, pregnant women also can be affected, among adults in general, as the condition is very contagious. You are at a greater risk of catching impetigo during the summer and early fall, and if you live in a warm, humid climate.
How is impetigo during pregnancy diagnosed?
Impetigo is diagnosed by way of examination of the sores and blisters and by swabbing samples from those sores and testing the samples for the presence of the bacteria.
Does impetigo cause problems during pregnancy?
Impetigo causes sores and blisters that can break, oozing out fluid, with itching along the way. The infection can lead to swollen lymph nodes and fever. Additionally, you can infect other people until the blisters all give way to scabs that have dried and crusted over for at least 24 hours. A fever can cause or exacerbate dehydration. If your impetigo is caused by S. pyogenes, failure to treat this with an antibiotic can lead to damage to one of your heart valves, leading to long-term heart trouble.
Does impetigo during pregnancy cause problems for the baby?
If you develop a fever, some studies are suggesting that this increases the babys risk of having congenital defects involving the heart and other organs. Also, a recent study identified maternal fever as a possible risk for the baby developing autism spectrum disorder.

For treating fever, acetaminophen and paracetamol are thought to be safe during pregnancy. For the treatment of the infection, there are several different antibiotic options, including many that are not considered dangerous during pregnancy. Antibiotic therapy is very important both to eliminate the infection quickly and to keep it from spreading to prevent long-term complications, such as a damaged heart valve.
Who should NOT stop taking medication for impetigo during pregnancy?
If you are given antibiotic therapy, it is very important that you do not stop the treatment before it is completed. If you experience adverse effects from the therapy, notify your doctor immediately because it may be necessary to stop the treatment (for instance, if you are having an allergic reaction to the treatment).

Impetigo is extremely contagious, and thus, the baby can catch it while nursing if you have sores or blisters. Consequently, it is important to take your antibiotic therapy.

If you are going to be continuing on an antibiotic regimen when you are cleared to breastfeed, your doctor can select an antibiotic that is safe for nursing mothers.
