Is it possible to have pertussis without cough?

While cough is a prominent symptom of pertussis, also known as whooping cough, it is possible for an individual to have the infection without experiencing a cough. This atypical presentation is more common in infants and young children, as well as in individuals who have been vaccinated against the disease.

Atypical pertussis may manifest with symptoms such as:

Runny nose

Sneezing

Low-grade fever

Lethargy

Poor feeding (in infants)

Difficulty breathing or wheezing

Apnea (cessation of breathing) in severe cases

In some cases, individuals may only experience mild respiratory symptoms or may mistake the infection for a common cold. This can make it challenging to diagnose pertussis, especially in the early stages of the infection.

It is important to note that pertussis can be a serious respiratory illness, particularly in young children and those with weakened immune systems. If you suspect that you or your child may have pertussis, it is essential to seek medical attention for prompt diagnosis and treatment.
