Health officials in the U.K. are warning the public about a concerning rise in whooping cough after cases soared 250% this year.

Between July and November, there were 716 reported cases of pertussis, a bacterial infection of the lungs, which is three times higher than the same period in 2022, the U.K.’s Independent reported, citing the U.K. Health Security Agency (UKHSA).

Dr Gayatri Amirthalingam, Deputy Director of Public Health Programmes at the agency, said the number of infections had decreased during the COVID-19 pandemic due to social distancing and lockdown policies, but is now on the rise again, according to the report.


Another expert, Professor Beate Kampmann, of the London School of Hygiene and Tropical Medicine, told The Sun, “The rise in cases might be because of missed vaccination appointments, possibly during the pandemic.”

“Severe disease is almost entirely preventable if the mother is vaccinated in pregnancy and her protective antibody reach the baby through the placenta and protect until the baby gets its own vaccines,” said Kampmann.

“It is therefore important that everyone looks at their vaccination records to check if they might have missed this vaccine, which is given with the routine childhood immunizations and in pregnancy.”

Pertussis, also called whooping cough, is a highly contagious respiratory disease that can cause serious illness, especially in babies and children. It is known for uncontrollable, violent coughing that can make it difficult to breathe, according to the National Institute of Allergy and Infectious Diseases.

In severe cases, intense coughing can lead to vomiting and sore or even fractured ribs. After fits of many coughs, an infected person may need to take deep breaths, which results in the “whooping” sound the disease is named for.

Another name for the disease is the 100-day cough, because it may last for several weeks or months, the U.K. National Health Service (NHS) says.
