Pertussis: Outbreak in the US, Concerns in Greece

Pertussis (whooping cough) is experiencing an outbreak in the United States, with an increase in cases, hospitalizations, and infant deaths in 2025. Despite the availability of a vaccine, the disease is re-emerging due to reduced vaccination rates and immunity.

Outbreak in the US: The CDC confirms a significant increase in pertussis cases in 2025, with outbreaks in several states. Only 92% of children aged 19-35 months have completed the DTaP vaccination, below the 94% threshold. Over 5,000 cases and at least 5 child deaths have been reported.

Situation in Greece: In 2024, there was a 4800% increase in pertussis cases compared to 2023, with 438 cases. 15% involved infants under two months, with two deaths and at least three hospitalizations in NICUs.

Prevention: Vaccination is crucial, starting from the 2nd month of life. Pregnant women should be vaccinated between the 27th and 36th week of pregnancy.

Measures in Greece: EODY recommends isolation of cases and antimicrobial treatment. Inadequately vaccinated children should be kept away from school for 21 days.
