Surge in Whooping Cough Cases in 2024: A Global Health Concern

Surge in Whooping Cough Cases in 2024: A Global Health Concern

In 2024, a notable resurgence in whooping cough (pertussis) has been reported across various regions, including the UK, Europe, and Australia. This resurgence highlights the cyclical nature of the disease and underscores the importance of vaccination in preventing outbreaks.

Rising Cases in the UK

The UK has witnessed a sharp increase in whooping cough cases, with 2,793 confirmed cases in the first quarter of 2024 alone. Tragically, this surge has resulted in five infant deaths. Infants under three months are particularly vulnerable to severe complications from the disease. The UK Health Security Agency (UKHSA) reported that 1,319 cases were confirmed in March 2024, following 556 cases in January and 918 in February​ (GOV.UK)​​ (BMJ)​.

The Situation in Australia

Australia is also grappling with a significant rise in whooping cough cases. The outbreak has been particularly pronounced among children aged 10-14. Experts attribute this increase to reduced immunity in the population, exacerbated by missed routine vaccinations during the COVID-19 pandemic. During the pandemic, measures such as lockdowns and mask-wearing led to a dramatic decline in whooping cough cases, which has now rebounded as these measures have been relaxed​ (Med Xpress)​.

Factors Contributing to the Resurgence

Several factors contribute to the current surge in whooping cough cases:

  1. Cyclical Nature of the Disease: Whooping cough tends to peak every three to five years. The last significant peak occurred in 2016, and another peak was anticipated. However, the COVID-19 pandemic interrupted the usual cycle, delaying the expected outbreak​ (GOV.UK)​​ (BMJ)​.
  2. Reduced Immunity: Public health measures during the pandemic led to a reduction in whooping cough cases, but also resulted in lower population immunity. This, combined with missed vaccinations, has made populations more susceptible to the disease​ (Med Xpress)​.
  3. Vaccine Hesitancy and Missed Vaccinations: There has been a decline in the uptake of whooping cough vaccinations, both for pregnant women and infants. Timely vaccination is crucial to protect vulnerable populations, particularly newborns who are too young to be fully vaccinated​ (GOV.UK)​​ (BMJ)​.

Importance of Vaccination

Vaccination remains the most effective defense against whooping cough. Pregnant women are advised to receive the whooping cough vaccine between 20 and 32 weeks of pregnancy, which helps pass on protection to the baby. Infants should receive three doses of the vaccine at 8, 12, and 16 weeks of age, with a booster at 3 years and 4 months​ (GOV.UK)​​ (Med Xpress)​.

In Australia, it's recommended that adults who are in close contact with infants receive booster shots, as immunity from the vaccine can wane over time. This is particularly important given the emergence of new bacterial strains that can evade the immune response triggered by current vaccines​ (Med Xpress)​.


The resurgence of whooping cough in 2024 serves as a stark reminder of the importance of vaccination and maintaining high levels of immunity within the population. Public health authorities continue to stress the need for timely vaccinations to protect the most vulnerable, particularly young infants, from this highly contagious and potentially deadly disease. Ensuring widespread vaccine coverage is essential to curbing the current outbreak and preventing future surges.
