Pertussis, also known as the Whooping Cough, is a lung infection caused by the bacteria Bordetella Pertussis.

 

It is highly contagious and can easily spread via respiratory droplets from coughing or sneezing. The cough is classically described as a series of severe, vigorous coughs followed by a ‘whooping’ inhale. This symptom is more prominent in infants and young children. The cough can also induce vomiting.

 

In severe cases, it can lead to breathing difficulties especially in those with pre-existing lung or heart conditions.

​

Infants and young children are more vulnerable to the infection.

 

As the pertussis vaccine can only be administered at 2 month-old onwards, active vaccination to pregnant ladies aims to facilitate transfer of passive immunity to the growing fetus. Active vaccination also helps to minimise the spread of pertussis within the community.

 

Unfortunately, the immunity against pertussis in previously vaccinated adults naturally declines with age. As such, active vaccination is highly encouraged in the following individuals: 

​

1. Children - given as part of the National Childhood Immunisation Schedule 

2. Pregnant ladies - given at 16 to 32 weeks & subsidised under the National Adult Immunisation Schedule

3. Adults with no previous immunisation or if their last vaccination > 10 years ago 

4. Adults in close contact with an infant < 12-month old

5. Unvaccinated healthcare personnel

​

Fortunately, pertussis is treatable with oral antibiotics. Regardless, prevention with active vaccination is always better than cure. Do visit your friendly doctor if you are unwell or have any queries regarding vaccination.
