GBS septicemia is caused by the bacterium <em>Streptococcus agalactiae</em>, which is commonly called group B strep, or GBS.</p><p>GBS is commonly found in adults and older children and usually does not cause infection. But it can make newborn babies very sick. There are two ways in which GBS can be passed to a newborn baby:</p><ul><li>The baby can become infected while passing through the birth canal. In this case, babies become ill between birth and 6 days of life (most often in the first 24 hours). This is called early-onset GBS disease.</li><li>The infant may also become infected after delivery by coming into contact with people who carry the GBS germ. In this case, symptoms appear later, when the baby is 7 days to 3 months or more old. This is called late-onset GBS disease. </li></ul><p>GBS septicemia now occurs less often, because there are methods to screen and treat pregnant women whose babies are at risk.</p><p>The following increase an infant's risk for GBS septicemia:</p><ul><li>Being born more than 3 weeks before the due date (prematurity), especially if the mother goes into labor early (preterm labor) and has not been screened for GBS</li><li>Mother who has already given birth to a baby with GBS sepsis</li><li>Mother who has a fever of 100.4°F (38°C) or higher during labor and has not been screened for GBS</li><li>Mother who has GBS in her gastrointestinal, reproductive, or urinary tract</li><li>Rupture of membranes (water breaks) more than 18 hours before the baby is delivered in a mother who has not been screened for GBS</li></ul></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Symptoms</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

If the bacteria are detected, women are given antibiotics through a vein during labor. If the mother goes into premature labor before 37 weeks and GBS test results are unavailable, she should be treated with antibiotics. Of note, a negative screen for the mother does not mean the baby has no risk for GBS septicemia, because the bacteria are not always detectable by screening.</p><p>Newborns who are at high risk are observed and sometimes tested for GBS infection, depending on their clinical status. They may receive antibiotics through a vein during the first 30 to 48 hours of life until test results are available. They should not be sent home from the hospital before 36 to 48 hours of age.</p><p>In all cases, proper hand washing by nursery caregivers, visitors, and parents can help prevent the spread of the bacteria after the infant is born.</p><p>Early diagnosis can help decrease the risk for some complications.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Alternative Names</h2></div><div class="section-button"><button type="submit" aria-controls="section-Alt" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
