Which are the symptoms of Pertussis?

Symptoms of Pertussis

Pertussis, commonly known as whooping cough, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. It primarily affects the respiratory system and can be particularly severe in infants and young children. The symptoms of pertussis can vary depending on the stage of the infection.

1. Catarrhal Stage:

The initial stage of pertussis, known as the catarrhal stage, resembles a common cold. The symptoms during this stage are mild and may last for 1-2 weeks. They include:

• Runny nose


• Mild cough


• Sneezing


• Low-grade fever


• Mild fatigue

2. Paroxysmal Stage:

The paroxysmal stage is characterized by severe coughing fits that can last for several weeks. These fits are often followed by a "whooping" sound when the person inhales, although this sound may be absent in infants. The symptoms during this stage may include:

• Frequent, rapid coughing spells


• Intense coughing fits, often ending with a high-pitched "whoop" sound


• Cyanosis (bluish skin color) due to lack of oxygen during coughing fits


• Vomiting or gagging after coughing fits


• Exhaustion and fatigue

3. Convalescent Stage:

The convalescent stage is the final stage of pertussis and can last for several weeks or even months. During this stage, the frequency and severity of coughing fits gradually decrease. The symptoms may include:

• Decreased frequency of coughing fits


• Mild cough


• Recovery from fatigue

It is important to note that the symptoms of pertussis can be milder in vaccinated individuals, especially those who have received the pertussis vaccine recently. However, vaccinated individuals can still contract and transmit the infection, albeit with less severe symptoms.

If you or your child experience persistent coughing fits or any of the symptoms mentioned above, it is crucial to seek medical attention. Early diagnosis and treatment can help prevent complications and reduce the spread of pertussis to others.
