What’s Whooping Cough?
Whooping cough, medically known as pertussis, is a highly contagious bacterial infection that affects the respiratory system. It is caused by the bacterium Bordetella pertussis and is characterized by severe coughing fits that can make it difficult for the individual to breathe. The condition is especially dangerous for infants, young children, and individuals with weakened immune systems.
Whooping cough got its name due to the distinctive “whooping” sound made when a person gasps for air after a coughing fit. Although vaccination has significantly reduced the incidence of pertussis, the disease still occurs, particularly in communities with low vaccination rates.
Signs and Symptoms of Whooping Cough
The symptoms of whooping cough usually appear in stages, and the severity of symptoms can vary. The disease can last from several weeks to months.
Common symptoms include:
1. Incubation Period:
- The time between exposure to the bacteria and the appearance of symptoms is typically 7 to 10 days but can range from 4 to 21 days.
2. Catarrhal Stage (1 to 2 weeks):
- Mild cold-like symptoms.
- Runny nose.
- Sneezing.
- Mild cough.
- Low-grade fever.
- This stage is highly contagious but may be mistaken for a common cold.
3. Paroxysmal Stage (2 to 4 weeks):
- This is the stage most characteristic of whooping cough.
- Severe coughing fits (paroxysms) that occur frequently.
- The coughing can be intense enough to cause vomiting or difficulty breathing.
- The hallmark “whooping” sound occurs after a coughing episode when the person inhales deeply.
- Exhaustion after coughing fits.
- The person may appear pale or even blue (cyanotic) from lack of air.
4. Convalescent Stage (Weeks to Months):
- Gradual recovery from coughing fits.
- Coughing may persist but decreases in frequency and severity.
- The individual may still be contagious, especially in the early part of recovery.
Whooping Cough Treatment and Control
While whooping cough can be serious, especially in infants and young children, it is treatable. Treatment often focuses on managing symptoms and reducing the severity of the disease.
Here are the main methods:
1. Antibiotics:
- Early treatment with antibiotics like azithromycin, erythromycin, or clarithromycin can reduce the severity of symptoms and help prevent the spread of the infection.
- Antibiotics are most effective if administered during the early stages (catarrhal stage), before the severe coughing fits begin.
- If the disease has progressed to the paroxysmal stage, antibiotics may not dramatically alter the course of the illness, but they can still help prevent complications.
2. Supportive Care:
- Because there is no specific antiviral treatment for whooping cough, management is primarily supportive.
- Keeping the airways clear and ensuring proper hydration is vital.
- Over-the-counter medications to manage cough or fever may be used, but these should be discussed with a healthcare provider to avoid any negative interactions or side effects.
3. Hospitalization:
- Severe cases, particularly in infants or individuals with underlying health conditions, may require hospitalization.
- In a hospital setting, individuals may receive oxygen therapy, intravenous fluids, and close monitoring.
4. Vaccination:
- The best way to prevent whooping cough is vaccination. The DTaP vaccine (diphtheria, tetanus, and acellular pertussis) is recommended for children in a series of five doses at 2, 4, 6, 15-18 months, and at 4-6 years of age.
- Adolescents and adults should receive the Tdap booster vaccine, especially if they are in close contact with infants, to prevent transmission.
- Pregnant women are advised to receive the Tdap vaccine during each pregnancy, ideally between 27-36 weeks of gestation, to protect their newborns.
5. Infection Control:
- Whooping cough is highly contagious, so people diagnosed with the disease should stay isolated until they are no longer contagious (usually after 5 days of antibiotic treatment).
- Those exposed to someone with pertussis, especially infants, may be given preventive antibiotics even if they are asymptomatic.

Frequently Asked Questions (FAQs) About Whooping Cough
1. How is whooping cough transmitted?
- Whooping cough is spread through respiratory droplets when an infected person coughs, sneezes, or talks. It can also spread by touching surfaces contaminated with the bacteria and then touching the face.
2. Who is at highest risk for severe whooping cough?
- Infants under 1 year old, particularly those younger than 6 months, are at the highest risk. Adults and older children can also become severely ill, but they are less likely to experience life-threatening complications than infants.
3. Can you get whooping cough more than once?
- Yes, it is possible to get whooping cough more than once. Immunity from the disease or vaccination wanes over time, which is why booster shots are recommended.
4. What are the complications of whooping cough?
- In infants and young children, complications may include pneumonia, seizures, brain damage, and death. In adults, complications are generally less severe but can include rib fractures from severe coughing or weight loss due to vomiting after coughing fits.
5. How long is someone contagious with whooping cough?
- A person with pertussis is contagious for about 2 weeks after the start of the cough, or until they have been on antibiotics for 5 days.
6. Can whooping cough be prevented?
- Yes, whooping cough can be largely prevented through vaccination. The DTaP and Tdap vaccines are effective at reducing the risk of infection and preventing severe disease.
7. Are antibiotics always necessary for whooping cough?
- Antibiotics are not always necessary once the disease has progressed to the paroxysmal stage, but they are helpful in the early stages to reduce symptoms and prevent transmission. People who are at high risk for complications should always receive antibiotics.
8. Can you still get whooping cough if you’re vaccinated?
- While the DTaP and Tdap vaccines provide significant protection, no vaccine is 100% effective. However, vaccinated individuals tend to experience milder symptoms and are less likely to develop serious complications compared to those who are unvaccinated.
In conclusion, whooping cough is a serious but preventable disease, especially when vaccination efforts are followed.
Early diagnosis, appropriate antibiotic treatment, and vaccination are key strategies in controlling and preventing pertussis.
Vigilance is particularly important for those in close contact with infants and young children to avoid the spread of this potentially deadly infection.
