Pertussis Concerns Rise in Italy, Impacting Sports and Public Health

A surge in pertussis, as well known as whooping cough, is raising concerns across Italy and Europe, extending beyond the typical childhood demographic. The European Centre for Disease Prevention and Control (ECDC) reported nearly 60,000 cases between March 2023 and May 2024 – more than ten times the number recorded in the previous two years. This increase is not only a public health issue but is also beginning to impact the sporting world, as evidenced by a recent outbreak within the Sassuolo Calcio football club. The heightened risk is particularly acute for infants under one year old.

What is Pertussis?

Pertussis is a highly contagious bacterial infection affecting the respiratory tract, caused by the bacterium Bordetella pertussis. A similar, though milder, illness – parapertussis – is caused by Bordetella parapertussis. The Italian National Institute of Health (ISS) classifies pertussis as a childhood disease, alongside rubella, measles, chickenpox, and mumps, primarily affecting children under five years of age.

How is Pertussis Transmitted?

Humans are the sole reservoir for the Bordetella bacterium, meaning transmission occurs exclusively between people. Experts emphasize that appropriate antibiotic treatment can lead to recovery within approximately two weeks. Still, unlike some other childhood illnesses, immunity gained from a pertussis infection isn’t lifelong and diminishes over time. The disease spreads through the inhalation of infected droplets from the nose or throat of an infected person, even those experiencing mild or no symptoms.

Symptoms of Pertussis

The ISS warns that the Bordetella pertussis bacterium can cause respiratory infections ranging from subtle to extremely severe, particularly in newborns. The hallmark symptom of pertussis is a persistent cough lasting more than three weeks. The illness typically begins with a mild cough, accompanied by a slight fever and nasal discharge – the catarrhal phase, lasting one to two weeks. This progresses to a paroxysmal phase, characterized by severe coughing fits and difficulty breathing, which can last for over two months without treatment. Following these fits, patients may experience apnea, cyanosis (bluish skin due to lack of oxygen), and vomiting.

Incubation Period and Contagiousness

The incubation period for pertussis is around 10 days. The ISS stresses that the disease is most contagious during the initial stages, before the onset of the characteristic paroxysmal cough. After three weeks of the paroxysmal phase, contagiousness is considered negligible in untreated patients. Antibiotic treatment reduces the infectious period to approximately five days after starting therapy. Transmission occurs via airborne droplets, likely through saliva released when an infected person coughs.

Treatment Options

Treatment for pertussis typically involves antibiotics, often erythromycin. Experts note that if administered before the paroxysmal phase, antibiotics can shorten the period of contagiousness and the duration of the illness, though they may not always alleviate symptoms entirely. Additional treatments to manage symptoms include cough suppressants, sedatives, and antispasmodics.

Vaccination: A Crucial Preventative Measure

Vaccination against pertussis is mandatory in Italy, beginning at eight weeks of age. Due to the waning of immunity over time, booster doses are necessary. The standard vaccination schedule includes initial doses at 6-8 week intervals, with a final booster dose administered around two years of age, according to the ISS.

The Impact on Sports: Sassuolo Calcio Outbreak

The recent outbreak within the Sassuolo Calcio locker room – with one confirmed case of pertussis and five players exhibiting compatible symptoms – has brought the disease back into the spotlight. Although the immediate impact on the team’s schedule remains to be seen, it underscores the potential for pertussis to disrupt sporting activities. This situation highlights the importance of vaccination and preventative measures, even among athletes who may have previously been vaccinated.

Pertussis Across Europe: A Growing Concern

The situation in Italy mirrors a broader trend across Europe. The ECDC’s data reveals a significant increase in pertussis cases throughout the continent between March 2023 and May 2024. This widespread resurgence emphasizes the need for increased awareness, vaccination efforts, and prompt diagnosis and treatment to control the spread of the disease.

What’s Next?

Public health officials in Italy and across Europe are continuing to monitor the situation closely. Increased vaccination campaigns and public awareness initiatives are expected to be implemented to curb the spread of pertussis. For Sassuolo Calcio, the team will be closely monitored, and further testing will be conducted to determine the extent of the outbreak and ensure the health and safety of all players and staff. The league will likely provide updates as the situation develops.

If you are experiencing symptoms consistent with pertussis, it is crucial to consult a healthcare professional for diagnosis and treatment. Staying informed and taking preventative measures, such as vaccination, are essential in protecting yourself and your community.
