Overview
Whooping cough, also called pertussis, is a serious bacterial infection of the respiratory system. The bacteria Bordetella pertussis causes this highly contagious disease. It gets its name from the distinctive "whooping" sound people make when trying to breathe after violent coughing fits.
This infection affects people of all ages but poses the greatest danger to babies and young children. Infants under 1 year old are most likely to develop severe complications. They may need hospital care and face life-threatening breathing problems.
Whooping cough spreads easily from person to person through tiny droplets in the air. When someone with the infection coughs, sneezes, or talks, they release bacteria that others can breathe in. The disease can spread before symptoms appear, making it particularly challenging to control.
The infection has been around for hundreds of years but became much less common after vaccines were created. Today, most cases happen in people who are not fully vaccinated. Even vaccinated people can sometimes catch whooping cough, though their symptoms are usually milder.
Symptoms & Signs
Whooping cough symptoms develop in stages over several weeks. Early signs often look like a common cold, which makes diagnosis difficult. The characteristic cough typically doesn't appear until the second stage of illness.
Primary Symptoms
Severe coughing fits - Rapid, repeated coughs that can last for minutes without stopping
Whooping sound - High-pitched gasping noise when trying to breathe between coughs
Vomiting after coughing - Intense coughing can trigger throwing up, especially in children
Exhaustion - Extreme tiredness from lack of sleep due to nighttime coughing episodes
When to Seek Care
Watch for signs of breathing difficulties, especially in infants and young children. Blue lips or face, inability to keep fluids down, or baby congestion and breathing issues require immediate medical attention.
Coughing fits can be scary to watch, especially in babies. Some people stop breathing briefly during severe coughing spells. If you notice your child turning blue or struggling to catch their breath, call 911 right away.
When to Seek Immediate Care
Contact emergency services if you notice blue coloring around the lips or face, severe breathing difficulties, or signs of dehydration from repeated vomiting.
Causes & Risk Factors
Age
Infants under 1 year face highest risk of severe complications
Vaccination Status
Unvaccinated or under-vaccinated individuals are most vulnerable
Immune System
Weakened immunity from illness or medications increases risk
Exposure
Close contact with infected people, especially in crowded settings

Diagnosis
Medical History & Physical Examination
Your healthcare provider will ask about your symptoms, including when the cough started and its characteristics. They'll want to know about recent contact with others who have been coughing or diagnosed with whooping cough. The doctor will listen to your lungs and check for signs of the distinctive whooping sound.
During the physical exam, your provider will look for signs of complications like pneumonia or breathing difficulties. They'll pay special attention to how well you can breathe between coughing episodes and check for signs of dehydration or exhaustion.
Diagnostic Testing
Nasopharyngeal swab - A sample from the back of the nose and throat to test for bacteria
Blood tests - Check for signs of infection and measure antibody levels against pertussis
Chest X-ray - Rule out pneumonia or other lung complications that can develop
Treatment Options
Treatment focuses on reducing symptoms and preventing the spread of infection to others. Early treatment works best, ideally within the first few weeks of illness.
Conservative Treatments
Antibiotics - Medications like azithromycin or clarithromycin help clear the bacteria and reduce contagiousness
Rest and hydration - Getting plenty of sleep and drinking fluids helps your body fight the infection
Humidified air - Using a cool-mist humidifier can help soothe irritated airways and reduce coughing
Antibiotics are the most important treatment for whooping cough. They work best when started early in the illness. Taking antibiotics as prescribed helps you feel better faster and stops spreading the disease to others.
Advanced Treatments
Hospitalization - Required for infants under 6 months or anyone with severe breathing difficulties
Oxygen therapy - Supplemental oxygen for patients with low blood oxygen levels during coughing fits
Mechanical ventilation - Breathing support for severe cases where patients cannot maintain adequate oxygen levels
Babies under 6 months almost always need hospital care for whooping cough. Hospitals can monitor them closely and provide oxygen if needed. Older children and adults usually recover at home with rest and medication.
Living with the Condition
Daily Management Strategies
Create a calm environment to reduce coughing triggers. Avoid smoke, dust, and strong odors that can worsen symptoms. Keep medications nearby and take them as prescribed. Small, frequent meals work better than large ones since coughing after eating can trigger vomiting.
Stay isolated from others until you've completed at least 5 days of antibiotic treatment. This prevents spreading the infection to family members and community contacts. Use tissues when coughing and wash hands frequently.
Getting through whooping cough takes patience since recovery is slow. Some people feel tired for weeks after the cough goes away. Having family support and following your doctor's advice helps you recover better.
Exercise & Movement
Avoid strenuous physical activity during the acute phase of illness. Gentle walking is usually acceptable, but stop if it triggers coughing fits. Rest is more important than exercise while recovering. Return to normal activities gradually as symptoms improve over several weeks.
Light movement like slow walking can help prevent blood clots and muscle weakness. However, anything that gets your heart racing too fast can trigger coughing spells. Once the worst coughing stops, you can slowly increase activity as you feel stronger.
Prevention
Vaccination - Get the DTaP vaccine series in childhood and Tdap booster shots as recommended
Isolation practices - Stay home from work or school until completing 5 days of antibiotic treatment
Hand hygiene - Wash hands frequently with soap and water, especially after coughing or sneezing
Respiratory etiquette - Cover coughs and sneezes with tissues or your elbow, not your hands
Vaccination is by far the best way to prevent whooping cough. Children need a series of shots starting in infancy. Adults need booster shots every 10 years to keep their immunity strong.
If you've been exposed to whooping cough, talk to your doctor about antibiotics. Taking antibiotics right after exposure can sometimes prevent infection or reduce symptoms. Your healthcare provider can help you decide if this is right for your situation.
Frequently Asked Questions
Whooping cough typically lasts 6 to 10 weeks total. The severe coughing stage usually peaks around 2-6 weeks after symptoms begin. Recovery is gradual, and some people may have occasional coughing episodes for months.
Yes, adults can definitely get whooping cough, especially if their immunity has faded over time. Adult cases are often milder than in children but can still cause weeks of severe coughing. Adults can spread the infection to vulnerable infants and children.
People with whooping cough are most contagious during the first 1-2 weeks when symptoms seem like a common cold. They may not know they have whooping cough yet, making early spread common. After 5 days of appropriate antibiotic treatment, people usually aren't contagious anymore.
The pertussis vaccine is highly effective but immunity can fade over time. It prevents about 80-90% of severe cases in the first few years after vaccination. Booster shots help maintain protection throughout life, which is why adults need periodic Tdap vaccines.
The most serious complications occur in infants and include pneumonia, brain damage from lack of oxygen, and seizures. Older children and adults may develop pneumonia, rib fractures from severe coughing, or hernias. Most healthy older children and adults recover completely without lasting effects.
