Whooping cough: how to tell it apart from a common cold

Whooping cough can initially resemble a common cold: a runny nose, mild discomfort and a moderate cough may appear, while the body temperature often remains normal or rises slightly. This is why it can be difficult to distinguish the two conditions based on symptoms alone during the first few days.

The main difference becomes apparent over time. With a common cold, the cough usually gradually subsides, whereas with whooping cough, it can become frequent, exhausting and paroxysmal. During these episodes, a person may experience repeated bouts of coughing, followed by a loud or high-pitched whooping sound when breathing in, and sometimes vomiting.

Why whooping cough initially resembles a common cold

The early symptoms of the disease are nonspecific. A person may experience a runny or stuffy nose, a mild cough and a low-grade fever. At this stage, the symptoms of whooping cough do not necessarily differ from those of an ordinary respiratory infection.

What matters is not only which symptoms appear but also how they change over the following days.

If the cough becomes more severe instead of gradually improving, occurs in fits or tends to recur mainly at night, this is a reason to consult a doctor for an assessment.

Whooping cough or a common cold: key differences

When trying to determine whether it is whooping cough or a common cold, the first things to consider are the nature and duration of the cough.

These signs can help identify a possible condition, but they do not replace a medical examination or laboratory testing.

How the cough changes with whooping cough

The cough associated with whooping cough is often the main symptom that distinguishes the disease from a common cold.

Initially, the cough may be mild. Over time, it can develop into repeated fits during which a person experiences several consecutive coughing spells. After a fit, a deep, loud or high-pitched whooping sound may occur when breathing in.

Severe coughing fits may also cause:

• facial redness or bluish discoloration;

• watery eyes;

• vomiting;

• significant fatigue after coughing;

• difficulty returning to normal breathing.

A paroxysmal cough is particularly concerning if it recurs over several days and gradually becomes more intense.

What signs may indicate whooping cough?

The most characteristic signs of whooping cough include prolonged, repeated coughing fits that may end with a distinctive whooping sound when inhaling or vomiting.

Whooping cough becomes more likely if:

• the cough does not subside but becomes more severe;

• coughing fits occur in repeated bursts;

• a high-pitched or noisy inhalation follows coughing;

• vomiting occurs after a coughing fit;

• the body temperature remains normal or slightly elevated;

• the cough lasts significantly longer than expected with a common cold.

   

However, the absence of a whooping sound when inhaling does not rule out whooping cough. Symptoms may vary depending on age, vaccination status and the course of the disease.

How long does whooping cough last?

Unlike a common cold, whooping cough can have a prolonged course. After the initial stage, which resembles a cold, the cough may become paroxysmal and persist for several weeks.

Therefore, the answer to the question of how long whooping cough lasts is not limited to a few days: the cough may continue for a long time even after other symptoms of the infection have subsided.

A prolonged cough does not necessarily mean that a person has whooping cough. However, if it becomes more severe or is accompanied by characteristic coughing fits, a medical consultation is necessary.

How is whooping cough diagnosed?

Symptoms alone can only raise suspicion of the disease. To determine the cause of the cough, a doctor assesses its nature, duration and associated symptoms and, if necessary, recommends laboratory testing.

The diagnostic approach depends on how long the disease has been present and the individual clinical situation. One method of confirming the diagnosis is a PCR test of a nasopharyngeal sample for Bordetella pertussis. Other laboratory methods may also be used at certain stages of the disease.

To undergo the necessary laboratory tests, you can visit the ZDRAVO medical center.

Whooping cough test: when is it needed?

A whooping cough test may be recommended if the cough has characteristic features or persists for an unusually long time. It is particularly important to tell your doctor when the cough started, how it has changed and whether coughing fits occur.

Laboratory test results should be interpreted alongside the symptoms. A negative result does not always rule out the disease at every stage, so the doctor determines the appropriate diagnostic approach.

Whooping cough in children: what to look out for

Whooping cough in children requires special attention because symptoms may vary depending on the child’s age. Young children may not develop the characteristic whooping sound after coughing, and breathing difficulties may manifest differently.

Parents should look out for:

• repeated severe coughing fits;

• vomiting after coughing;

• difficulty breathing or irregular breathing;

• bluish discoloration of the lips or skin;

• unusual lethargy;

• refusal to eat or drink.

   

If significant breathing difficulties occur, seek immediate medical attention. For an initial assessment of a child’s condition, you can consult a pediatrician.

When should you see a doctor?

Do not wait until the cough becomes very severe if it is gradually worsening or developing into coughing fits.

It is particularly important to seek medical assessment if you experience:

• difficulty breathing or interrupted breathing;

• bluish discoloration of the lips or face;

• repeated vomiting after coughing fits;

• very severe or frequent coughing fits;

• significant weakness;

• a persistent cough that shows no signs of improvement.

   

If necessary, you can have your respiratory system assessed by a pulmonologist, or arrange an initial consultation with a family doctor.

Conclusion

Whooping cough can initially resemble a common cold, which makes the progression of symptoms particularly important. If the cough becomes paroxysmal instead of improving, or if repeated coughing fits, a whooping sound when inhaling or vomiting after a coughing episode occur, you should consult a doctor.

It is impossible to determine the exact cause of a persistent or characteristic cough based on symptoms alone. Laboratory tests, including PCR, may be used to confirm whooping cough.
