Overview
Whooping cough, also known as pertussis, is a highly contagious respiratory tract infection. It is characterized by a severe hacking cough followed by a high-pitched intake of breath that sounds like "whoop." The infection is primarily caused by the bacteria Bordetella pertussis and is transmitted through airborne droplets from infected individuals. Whooping cough mainly affects children too young to have completed the full course of vaccinations and teenagers and adults whose immunity has faded. Symptoms resemble those of a common cold at first and include a runny nose, nasal congestion, vomiting, and difficulty breathing. Complications are generally mild for teens and adults, while infants, especially those under 6 months of age, are at a higher risk of severe complications, such as pneumonia, slowed or stopped breathing, dehydration, seizures, and even brain damage. Prevention is best achieved through vaccination, which typically involves a series of five injections given at various ages, beginning in infancy.
Understanding the disease
Symptoms
The symptoms of whooping cough (pertussis) include a severe hacking cough followed by a high-pitched intake of breath that sounds like "whoop." Other symptoms are similar to those of a common cold, such as a runny nose, nasal congestion, vomiting, turning red or blue, and struggling to breathe or having noticeable pauses in breathing. Infants may not cough at all and may instead experience severe complications like pneumonia, slowed or stopped breathing, dehydration, seizures, or brain damage.
Risk Factors
Risk factors for developing whooping cough include:
- Age: Infants under 6 months old are at the greatest risk of severe complications and potential life-threatening consequences from whooping cough.
- Vaccination status: Whooping cough primarily affects children too young to have completed the full course of vaccinations and teenagers and adults whose immunity has faded.
- Outbreaks: There are regular outbreaks of whooping cough, which increases the risk for individuals who are not up-to-date with their vaccinations.
- Weakened immune system: People with weakened immune systems due to conditions like HIV/AIDS, cancer, or those taking immunosuppressive medications may be at a higher risk for developing severe complications from whooping cough.
- Close contact with infected individuals: Those who have close contact with someone who has whooping cough are at an increased risk of contracting the illness. Remember to practice good hygiene, such as frequent handwashing and covering your mouth and nose when you cough or sneeze, to reduce the spread of the disease.
Development
Whooping cough develops from infection with the bacteria Bordetella pertussis. Once infected, it takes about 7 to 10 days for signs and symptoms to appear, which typically resemble those of a common cold. These mild initial symptoms include a runny nose, nasal congestion, and a slight cough. As the infection progresses, the cough becomes more severe and may cause vomiting, turning red or blue, and noticeable pauses in breathing. The cough may also be accompanied by a whooping sound when inhaling. Complications for infants, especially those under 6 months of age, can be severe and may include pneumonia, slowed or stopped breathing, dehydration, seizures, and even brain damage. In teens and adults, complications are generally milder and may involve bruised or cracked ribs, abdominal hernias, and broken blood vessels in the skin or eyes. The best way to prevent whooping cough is through vaccination, typically given in a series of five injections for children, beginning at 2 months of age.
Assessment and Diagnosis
Triage
You should see a doctor if whooping cough is suspected when there are symptoms such as a severe hacking cough followed by a high-pitched intake of breath that sounds like "whoop," vomiting, turning red or blue, seeming to be struggling to breathe or having noticeable pauses in breathing, or inhaling with a whooping sound. If these symptoms occur or if someone has been exposed to someone with whooping cough, it's important to consult a doctor for proper evaluation and treatment.
Diagnosis
To diagnose whooping cough, doctors may use a combination of symptom evaluation, medical tests, and physical examination. In the early stages, diagnosing whooping cough can be challenging since its symptoms resemble those of common respiratory illnesses like a cold, the flu, or bronchitis. Here are some methods doctors may employ to diagnose whooping cough:
- Symptom evaluation: Doctors may ask about the presence of characteristic symptoms such as a long-lasting, severe cough followed by a whooping sound, difficulty breathing, and vomiting after coughing.
- Medical tests: Tests like nose or throat cultures and tests, blood tests, and chest X-rays may be conducted to confirm the presence of whooping cough bacteria, assess the severity of the infection, and check for complications like pneumonia.
- Physical examination: Doctors may use a stethoscope to listen closely to the patient's lungs, check for signs of inflammation or fluid in the lungs, and assess the overall health of the patient. It's important to consult a healthcare professional if you suspect whooping cough or if you or your child are experiencing persistent coughing, difficulty breathing, or other concerning symptoms.
Management and Treatment
Complications
Potential complications of whooping cough include:
- Bruised or cracked ribs
- Abdominal hernias
- Broken blood vessels in the skin or the whites of your eyes
- Pneumonia
- Slowed or stopped breathing
- Dehydration or weight loss due to feeding difficulties
- Seizures
- Brain damage Complications in infants, especially those under 6 months of age, can be more severe and may lead to life-threatening situations.
Prevention
whooping cough can be prevented with the pertussis vaccine, which is typically given in combination with vaccines against diphtheria and tetanus. The vaccine is recommended to be started during infancy, and consists of a series of five injections given at the following ages: 2 months, 4 months, 6 months, 15 to 18 months, and 4 to 6 years. The vaccine's effectiveness may wear off over time, leaving teenagers and adults susceptible to infection during outbreaks. To reduce the risk of complications and severe illness, it's essential to receive the recommended vaccinations and follow proper hygiene practices to prevent the spread of the disease.
Treatment
Treatment for whooping cough typically involves supportive care and addressing the symptoms. Antibiotics may be prescribed for those with severe or prolonged illness, but they do not alter the course of the disease or reduce the severity of symptoms. The focus is on alleviating symptoms and preventing complications. For infants and young children, who are at higher risk for complications, treatment may include:
- Antibiotics: Infants and young children may be prescribed antibiotics to reduce the severity and duration of the illness, as well as to prevent the spread of infection to others.
- Hospitalization: In severe cases, infants may need hospitalization to receive close monitoring and supportive care, such as oxygen therapy, hydration, or nutritional support.
- Medications to manage symptoms: Infants may receive medications to help with cough, fever, or pain.
- Vaccination for close contacts: Pregnant women and those who will have close contact with infants should receive the pertussis vaccine to reduce the risk of transmission. For teens and adults, treatment largely involves managing symptoms and preventing complications, such as:
- Rest: Getting plenty of rest can help with recovery.
- Hydration: Drinking plenty of fluids can help prevent dehydration caused by coughing and fever.
- Over-the-counter medications: Pain relievers and fever reducers, like acetaminophen or ibuprofen, can help alleviate symptoms. Cough suppressants may also be recommended in some cases.
- Antibiotics: While antibiotics do not cure whooping cough, they may be prescribed to prevent complications in certain situations, such as in those with underlying medical conditions or weakened immune systems. It is important to note that vaccination is the most effective way to prevent whooping cough.
Preparing for medical consultation
To prepare for an appointment regarding whooping cough (also known as pertussis), follow these steps:
- Review pre-appointment restrictions: When scheduling the appointment, inquire about any restrictions you should follow in the time leading up to the visit, such as isolating yourself to avoid spreading the infection.
