Pertussis
4 Épidémie ActivesPertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It causes severe coughing fits that can last for weeks or months.
Qu'est-ce que Pertussis?
Pertussis, commonly known as whooping cough, gets its name from the distinctive 'whooping' sound made when gasping for air after a coughing fit. Before the vaccine was developed, pertussis was a leading cause of childhood death worldwide. Today, it remains a serious threat, especially to infants who are too young to be fully vaccinated.
SymptĂ´mes
- Initial cold-like symptoms (runny nose, mild fever)
- Severe, uncontrollable coughing fits
- Whooping sound when gasping for air
- Vomiting after coughing
- Exhaustion after coughing fits
- Apnea (pauses in breathing) in infants
Transmission
Pertussis spreads through respiratory droplets when an infected person coughs or sneezes. It is highly contagious, especially in the first two weeks when symptoms resemble a common cold. Close contact with infected individuals poses the highest risk.
Période de Contagiosité : From early cold-like symptoms through 3 weeks after coughing begins (or 5 days after starting antibiotics)
Prévention
- DTaP vaccine for infants and children (5 doses by age 6)
- Tdap booster for adolescents (age 11-12) and adults
- Tdap during each pregnancy (27-36 weeks) to protect newborns
- Isolation of infected individuals
- Prophylactic antibiotics for close contacts
- Practice respiratory hygiene and handwashing

Pertussis Outbreak: Australia Faces Record Whooping Cough Cases
Australia experienced an unprecedented surge in pertussis (whooping cough) during 2024–25, with more than 82 000 cases reported, disproportionately affecting children under 14 and concentrated in New South Wales and Queensland. The outbreak reflects a convergence of waning population immunity and declining vaccination coverage below the 95% herd‑immunity threshold, compounded by reduced immune boosting during COVID‑19 restrictions and lower uptake among adults and pregnant women. Early 2026 trends remain concerning, with cases already accumulating and warning signs including infant infections, antibiotic resistance, and sustained transmission, indicating the need for strengthened national vaccination and public health responses.

Honduras Pertussis Outbreak: 91 Cases, Nine Deaths
Honduras is seeing an increase in pertussis cases and infant deaths, with transmission reported across most health regions. This reflects a wider post-pandemic resurgence of whooping cough throughout the Americas, caused by waning immunity and inadequate vaccination coverage.
