What are the 4 Stages in Whooping Cough that can Cause Damage to Lungs?

In medical terms, pertussis is whooping cough, a respiratory infection easily transmitted and caused by Bordetella pertussis. While it is commonly thought of as a childhood disease, it can affect people of any age. Understanding the stages of whooping cough is critical because it may result in significant health problems, especially those connected to lung health. In this blog, we delve into the four stages of whooping cough, its causes, treatment, and how they can potentially cause damage to the lungs.

Causes of Whooping Cough

Whooping cough is a disease that occurs when an individual gets infected with the bacterium Bordetella pertussis. Bacteria cling to the cilia (fine hairs) in the respiratory tract, thus causing swelling and damage. The infection is spread via respiratory droplets when an infected person coughs or sneezes; therefore, close contact with an infected person becomes a significant risk factor for transmission.

Whooping Cough Symptoms

• Persistent coughing fits
• Intense coughing followed by a "whooping" sound when inhaling
• Rapid coughs in succession
• Vomiting after coughing fits
• Fatigue and exhaustion
• Runny nose
• Sneezing
• Low-grade fever
• Difficulty breathing, especially in infants
• Symptoms may mimic a common cold initially, but the cough worsens over time.

Stages of Whooping Cough

Stage 1: Incubation Period

The period, known as the incubation period of whooping cough, lasts around 7 to 10 days, during which the bacterium Bordetella pertussis begins to multiply in the respiratory tract. The virus is spread mainly by the respiratory droplets when an infected person coughs or sneezes. At this stage, the person may not experience any whooping cough symptoms but can still transmit the bacteria to others, leading to early detection and prevention difficulties.

Stage 2: Catarrhal Stage

The catarrhal stage is where the signs of whooping cough resemble a common cold or a mild respiratory infection. These signs may include a runny nose, slight fever, sneezing, and mild cough. On the other hand, what sets whooping cough apart from other respiratory illnesses is that the cough worsens over time.

Stage 3: Paroxysmal Stage

The paroxysmal stage is characterised by extreme and uncontrollable coughing attacks that can be tiring and disturbing for the patient. Such episodes are accompanied by a series of coughs followed by a quick and sharp breath intake, producing a recognisable "whooping" sound. These episodes of coughing can be bad as they make the patient feel like vomiting and exhausted, and in some cases, they even get broken ribs.

Although the primary cause of coughing was the body's immune response to the bacteria and the toxicants they produce, it could also damage the delicate tissues of the lungs. Continuous and forceful coughing can cause swelling, discomfort, and even bleeding in the respiratory tract, increasing the risk of developing pneumonia and respiratory failure.

Stage 4: Convalescent Stage

This stage is characterised by a slow recovery from the disease, which may take several weeks or even months. Cough could persist during this period. This period is quite a crucial one with a high risk of complications. Therefore, the patient should seek medical care and support to recover and prevent further problems or aggravation of symptoms.

How to Diagnose Whooping Cough?

Diagnosing whooping cough can be done using a combination of clinical assessment, laboratory tests and imaging studies. Nasopharyngeal swabs or throat cultures may isolate the bacterium Bordetella pertussis, while a blood test may show increased white blood cells, indicating inflammation. Chest X-rays and other exams may be used to assess the extent of lung involvement and rule out complications like pneumonia.

Treatment Options for Whooping Cough

1. Antibiotics like azithromycin or erythromycin that kill Bordetella pertussis bacteria are usually prescribed to treat the infection.
   
2. Administering antibiotics early in the illness, preferably during the catarrhal or early paroxysmal stage, increases their effectiveness in reducing symptom severity and duration.
3. Supportive care measures play a crucial role in managing whooping cough symptoms and preventing complications:
4. It is important to allow the body to rest to recover and battle the infection well.
5. Keeping well-hydrated allows mucus to be loosened, making it easier for it to be coughed up and clear the airways.
6. Respiratory support, like humidifiers or nebulizers, can minimise respiratory problems and alleviate sore airways.
7. Patients with severe symptoms or complications may need to be hospitalised in a special ward for close monitoring and treatment, including oxygen therapy or intravenous fluids.
8. Vaccination remains the most effective strategy for preventing whooping cough, emphasising the importance of adhering to recommended immunisation schedules for individuals of all ages.

Conclusion

Pertussis, widely known as whooping cough, is a contagious respiratory disease that affects the lungs and can have severe consequences, especially concerning lung health. By comprehending the four stages of whooping cough, its causes, diagnosis, and treatment options, people and healthcare providers can easily identify and prevent complications related to this disease. Timely diagnosis, immediate treatment, and supportive care are important in preventing whooping cough progression and quick recovery.

FAQs (Frequently Asked Questions)

1. Is there a vaccine available for whooping cough?
   
   Answer:- Yes, there is a vaccine for whooping cough, usually administered as part of the DTaP (diphtheria, tetanus, and acellular pertussis) vaccine in childhood and Tdap (tetanus, diphtheria, and acellular pertussis) vaccine for adolescents and adults.
   
   
2. How close do you need to be to someone with a whooping cough to catch it?
   
   Answer:- Whooping cough is highly contagious and can spread through respiratory droplets from coughing or sneezing.
   
   
3. What precautions can I take to prevent whooping cough?
   
   Answer:- Vaccination is the most effective way to prevent whooping cough. Additionally, practising good respiratory hygiene, such as covering your mouth and nose when coughing or sneezing, can help reduce the risk of transmission.
   
   
4. At what age are individuals most susceptible to whooping cough?
   
   Answer:- While whooping cough can affect individuals of any age, infants and young children are at the highest risk.
   
   
5. How severe can whooping cough be?
   
   Answer:- Whooping is a serious infection. Complications can include pneumonia, seizures, brain damage, and even death, particularly in infants and young children.
