Pertussis (whooping cough)

Pertussis is a bacterial respiratory infection. A persistent cough may exist without the characteristic song.

Documentary Enrichment: · General information

Essentials

Very contagious respiratory infection that can be particularly severe in infants.

Agent
Bordetella pertussis
Transmission or exposure
Respiratory

Situation and vulnerability

Infants can develop severe forms with respiratory pauses. The contacts of their entourage deserve special attention.

Signs and limits of their interpretation

A cold-like start may precede quintae, vomiting after coughing and fatigue. In infants, apnea may be in the foreground.

Diagnosis and monitoring

The history of contacts and adapted respiratory sampling help to diagnose. The duration of the cough influences the choice and interpretation of the exams.

Prevention and care

Vaccination according to schedule, including recommendations during pregnancy, protects targeted populations. Treatment and management of contacts are the responsibility of the professional.

Practical issues

Can a vaccinated person still have a whooping cough?

Yes. Protection decreases over time; symptoms may be less typical. Report a persistent cough before you meet an infant.

Preparing for an exchange with a professional

  • Start and frequency of quintets
  • Contacts with infants
  • Vaccine dates and treatments

Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.

Individual decisionThe choice of a test, treatment or prevention depends on the local situation and recommendations. In case of distress, call 911.
