We’ve reached that not-so-wonderful time of year when it seems like everywhere you go, everyone is coughing – trying to avoid catching something feels like an extreme sport. For most people unlucky enough to join the ranks, a cough might make them feel rough, but shouldn’t be too much cause for concern. However, with COVID-19 still circulating and a resurgence of whooping cough, it helps to know the difference between them.

Whooping cough

Whooping cough, or pertussis, is a bacterial infection and is also known as the “100-day cough” because of how long it can last for; according to the NHS, it “may last for several weeks or months”. It’s a concern at the moment in the UK, with cases having risen from 69 in 2022 to 856 in 2023, with nearly 30 percent of those reported in December.


In its early days, the infection appears much like a regular cold, with symptoms such as a runny nose or a sore throat. It’s usually after around a week or two that the coughing starts. As Professor Paul Hunter described in The Conversation, this coughing comes in intense bouts. “Each bout can last several minutes and is occasionally followed by the loud whoop that gives the disease its name. Afterwards, a chronic cough can remain for several weeks.”

The bouts of coughing often lead to mucus being expelled and can sometimes be so intense that they can cause vomiting or breathing difficulties; the risk of the latter is higher in babies under 6 months old. 


COVID-19, on the other hand, is a viral infection. As with many respiratory illnesses, cases have seen an uptick in the winter months, and currently the relatively new JN.1 is the most prevalent variant of the virus worldwide.


Though symptoms of JN.1 can also include fever, fatigue, and body aches, one of the characteristic signs of COVID that’s persisted through the evolution of the disease is, coincidentally, a persistent cough. That’s part of what sets it apart from whooping cough; COVID-19 can give a continuous cough as opposed to coughing fits.

There’s also the way the cough sounds and feels. A COVID cough often starts with a tickle in the throat and the resulting cough is dry, usually making quite a coarse sound. In comparison, whooping cough is wet – remember that mucus can be coughed up – and has the distinctive “whoop”.

If a cough doesn’t feel like any of those and you have the symptoms of a regular cold, it’s likely that it’s just that. However, as always, if a cough is causing you concern or doesn’t seem to be going away, the best approach is to speak to a healthcare professional in order to figure out its cause and the best course of action.
