What is Whooping Cough (Pertussis)?

Whooping⁤ cough, also known as pertussis or the “100-day cough,” is a⁣ highly contagious respiratory infection caused by the bacterium Bordetella pertussis.Its characterized ⁤by severe coughing fits followed by a “whooping” sound when the person breathes in. The Centers⁣ for Disease Control and Prevention (CDC) provides extensive details‍ on pertussis.

Infants ‍are particularly vulnerable to severe complications from whooping cough, including pneumonia, seizures,⁣ brain damage, and even death. Their immune systems are not fully developed, and they haven’t completed their vaccination series.

The Situation in Chile

Chile has experienced a significant increase in whooping cough cases,⁣ exceeding expected‍ figures.Newborns are disproportionately affected,⁣ highlighting ‍the urgency of preventative measures. La Tercera⁣ reported on the rising ‍cases and concerns in May 2024.

The vulnerability of newborns stems from the⁤ fact that vaccination against pertussis in Chile begins at two months of age. This leaves⁢ a critical window of susceptibility during the first few months of life.

The Role of maternal DTPA⁣ Vaccination

The DTPA (diphtheria, tetanus, and acellular pertussis)⁤ vaccine is recommended ⁣for pregnant women during each pregnancy, ideally between 27 and 36 weeks of gestation. The American⁤ College of Obstetricians and Gynecologists (ACOG) details the benefits⁣ and recommendations for maternal pertussis vaccination.

Luz Román, an academic at the Obstetrics School of Andrés Bello University, explains⁢ that babies have a period of lower protection and ⁤are exposed to caregivers and family members who might potentially be carriers of the bacteria. ‍Vaccinating the mother boosts her antibody levels, which are then passed to⁤ the ⁤baby, providing passive immunity during the vulnerable early months.

Though, the effectiveness of this passive immunity wanes over time. The timing of the maternal vaccination is crucial to maximize the antibody transfer and provide the longest possible protection for the infant.

Preventive Measures and Recommendations

• Maternal Vaccination: Pregnant women should receive the DTPA vaccine during each pregnancy, ideally between 27 and⁣ 36 weeks.
• cocooning: Close contacts of newborns, including parents, siblings, and ⁣caregivers, should be vaccinated against pertussis to create a ⁣”cocoon” of protection.
• Early Vaccination: Ensure infants receive their pertussis vaccinations on schedule, starting at two months of age.
• Hygiene: Practice good hygiene, such as frequent handwashing, to prevent the spread of respiratory infections.
