Whooping Cough Infection
Whooping cough, also known as pertussis, is a highly contagious respiratory infection  that causes severe and 
persistent coughing spells. While early symptoms may resemble a common cold, the condition can worsen over 
time and significantly affect breathing, especially in infants, older adults, and individuals with existing lung 
conditions. Early recognition and proper management are essential to prevent complications.
Understanding Whooping Cough (Pertussis)
Whooping cough is caused by a bacterial infection that targets the airways and leads to inflammation, mucus 
buildup, and irritation of the respiratory tract. The infection spreads easily through droplets released during 
coughing or sneezing, making close-contact environments more vulnerable to transmission. Because early 
symptoms are mild, many people may unknowingly spread the illness before severe coughing begins.
Causes and Transmission of the Infection
Pertussis develops when bacteria attach to the lining of the airways and release toxins that damage the 
respiratory tract. The infection spreads through close contact, shared spaces, and prolonged exposure to 
infected individuals. Since it begins like a routine respiratory infection, timely identification is often delayed, 
increasing the risk of community spread.
Symptoms You Should Never Ignore
As the illness progresses, symptoms become more severe and distinctive. Warning signs include 
repeated coughing fits, difficulty breathing during episodes, vomiting after coughing, extreme fatigue, 
and a high-pitched “whoop” sound while inhaling. Infants may not produce the classic cough but can 
show breathing pauses, poor feeding, or bluish skin. Individuals with Asthma or other lung conditions 
may experience worsening respiratory distress and require closer monitoring.
Diagnosis and Treatment Approach
Diagnosis is based on symptom patterns, physical examination, and laboratory tests to confirm the bacterial 
cause. Early treatment helps reduce severity and prevents transmission. Antibiotics are commonly used to 
control the infection, while supportive care focuses on rest, hydration, clean air, and symptom relief. In severe 
cases, especially in infants or high-risk individuals, close medical supervision may be necessary to manage 
breathing difficulties and complications.
Conclusion: Early Action Prevents Complications
Whooping cough is a serious respiratory infection that should not be ignored, particularly when symptoms 
persist or worsen. Understanding how the infection spreads, recognising early warning signs, and seeking 
timely medical care are crucial steps in preventing complications. Prompt attention is especially important for 
infants, older adults, and people with underlying conditions such as Asthma, as early care can significantly 
improve recovery and outcomes.
