The UK has been grappling with a large outbreak of pertussis, commonly known as whooping cough, since the beginning of 2024. There have been 2,793 confirmed cases of the infection so far this year, with a particularly distressing statistic of five infant deaths attributed to whooping cough. Reports also suggest the possibility of a sixth infant fatality due to the bacterial infection. These tragic deaths serve as a stark reminder of the severity of whooping cough, especially in vulnerable populations such as babies.

Whooping cough is caused by the Bordetella pertussis bacterium and typically starts off with symptoms similar to other respiratory infections, such as a runny nose and fever. The distinctive “whoop” cough may manifest after about a week of illness, although it may not be present in all cases. The infectiousness of whooping cough is a cause for concern, with an average of 15-17 individuals being infected by a single case. This high transmission rate is attributed to the prolonged period of infectivity, which can last up to five weeks. Prompt treatment with antibiotics can significantly reduce transmission and contagiousness within a short period.

Vaccination plays a crucial role in preventing whooping cough and its tragic consequences. The pertussis vaccine is highly effective and safe, offering protection against the infection. Maintaining high vaccine uptake rates across the population is essential in preventing severe outbreaks. Vaccinating young children and pregnant women, who are particularly vulnerable to the disease, is key to reducing the incidence of whooping cough. Fully vaccinated children have an 84 percent lower risk of infection compared to those who are not vaccinated.

Despite the effectiveness of the pertussis vaccine, there has been a concerning decline in vaccine coverage in recent years. Maternal vaccine uptake dropped from 70 percent in 2017 to 58 percent in 2023, while the percentage of children vaccinated by their first birthday also saw a slight decrease. This decline in vaccine coverage may be a contributing factor to the current outbreak of whooping cough in the UK.

To control the ongoing outbreak, widespread use of antibiotics for treating or preventing pertussis infections may be necessary. Individuals who suspect they have whooping cough should seek medical attention promptly to reduce their infectious period. While the pertussis vaccine is not routinely recommended for adults, an extra dose may be advised for those in close contact with infected individuals or at higher risk of severe infection.

Accurate and informative public health messaging is crucial in raising awareness and educating the public about preventing the spread of whooping cough. While speculation about the outbreak being linked to lockdowns lacks evidence, it is essential for high-profile media sources to report accurate information to guide public health behaviors. Access to healthcare and vaccination rates may have been impacted by the pandemic, resulting in decreased population-wide immunity needed to prevent severe outbreaks.

The outbreak of whooping cough in the UK highlights the importance of vaccination and access to accurate information. Preventable through vaccines, whooping cough can have devastating consequences, especially for vulnerable populations such as infants. By maintaining high vaccine coverage rates and ensuring prompt treatment, efforts can be made to control and prevent future outbreaks of this infectious disease.
