Whooping cough, or pertussis, is often thought of as a childhood illness—yet in recent years, cases among adults have sharply increased. Because immunity from childhood vaccination fades over time, adults are again becoming carriers and victims of this once-rare disease.

Why Whooping Cough Is Returning

• Waning immunity: Tdap protection decreases after 5–10 years.

• Lower vaccination rates in many regions.

• Highly contagious bacteria (Bordetella pertussis) spreading easily in crowded environments.

Adults now account for a large portion of outbreaks.

Symptoms of Whooping Cough in Adults

1. Prolonged Coughing Fits

Coughing spells lasting weeks to months.
Many adults think it’s bronchitis or allergies.

2. The “Whoop” Sound

Some adults still develop the trademark high-pitched “whoop” when inhaling, but many DO NOT — making diagnosis harder.

3. Post-Cough Vomiting

A key sign — intense coughing can trigger gagging or vomiting.

4. Rib Pain and Fatigue

Coughing fits strain the muscles of the chest.

5. Nighttime Worsening

Symptoms typically intensify at night.

Why It’s Dangerous for Adults

Whooping cough can lead to:

• cracked ribs

• pneumonia

• severe exhaustion

• passing the infection to infants (lifethreatening)

Adults often delay treatment, allowing the infection to spread.

Diagnosis

Pertussis is identified using:

• nasal swab

• PCR test

• blood antibody testing

Treatment Options

1. Antibiotics

Azithromycin, erythromycin, or clarithromycin are most effective when started early.

2. Cough Management

Humidifiers, hydration, warm fluids, and avoiding irritants help reduce symptoms.

3. Vaccination Boosters

Adults should receive a Tdap booster every 10 years, especially caregivers and healthcare workers.

Prevention

• Boosters

• Avoid close contact during outbreaks

• Good hygiene

• Wearing masks in crowded places during respiratory surges
