What Is Whooping Cough in Infants
Whooping cough, or pertussis, is a highly contagious respiratory infection caused by Bordetella pertussis. In infants, especially those under 6 months, it can lead to severe complications including pneumonia, seizures, brain damage, and infant death. Newborns often do not show the classic "whoop" sound and may instead experience pauses in breathing or turning blue.
Why Infant Death Can Occur
Infant death from whooping cough often results from apnea, where breathing stops for long periods. The infection can cause violent coughing that exhausts tiny lungs and reduces oxygen supply. Babies may struggle to eat or drink, leading to dehydration and weight loss. Without prompt hospital care, the disease can progress rapidly to respiratory failure.
Prevention and When to Seek Help
The most effective protection is maternal vaccination during pregnancy and timely infant immunization starting at 2 months. If a baby shows signs such as coughing fits, vomiting after coughing, or breathing pauses, seek emergency care immediately. Early treatment with antibiotics can reduce severity and lower the risk of severe outcomes.
