Summary
Pertussis cases surged in Poland in 2023, with incidence rising 150% due to waning immunity and increased social contact post-pandemic. This highlights pertussis as a continuing public health concern, especially for unvaccinated infants.
Area of Science:
- Epidemiology
- Public Health
- Infectious Disease Surveillance
Background:
- Poland observed a significant rise in pertussis (whooping cough) cases in 2023, mirroring a European trend of increased respiratory illnesses post-COVID-19.
- Contributing factors include decreased population immunity, vaccination delays, and diagnostic challenges, particularly in adult and adolescent populations.
- The resurgence underscores the impact of the pandemic on routine immunization programs and disease transmission dynamics.
Purpose of the Study:
- To analyze the 2023 pertussis epidemiological landscape in Poland.
- To compare current pertussis incidence with previous years, assessing the pandemic's influence.
- To evaluate the vaccination status of children concerning pertussis.
Main Methods:
- Analysis of individual pertussis case reports from the EpiBaza system at the National Institute of Public Health NIH - National Research Institute.
- Utilization of data from annual bulletins: "Infectious diseases and poisonings in Poland" and "Vaccinations in Poland in 2023".
- Epidemiological assessment based on registered cases and vaccination records.
Main Results:
- A total of 922 pertussis cases were recorded in 2023, marking a 150% increase from 2022, with an incidence rate of 2.45 per 100,000 population.
- The highest incidence was observed in young children (0-4 years) at 17.3/100,000, followed by children aged 5-9 years (7.6/100,000).
- A significant proportion, approximately 45%, of pertussis cases occurred in individuals over 15 years of age.
Conclusions:
- Pertussis cases more than doubled in Poland in 2023, linked to the lifting of pandemic restrictions and increased social interactions.
- Pertussis remains a critical public health threat, with declining post-vaccination immunity facilitating transmission among adolescents and adults, posing a risk to infants.
- The study emphasizes the need for robust vaccination strategies and surveillance to mitigate pertussis resurgence.

01:28Infectious Diseases and Their Occurrence
67
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...

2.3K
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:28Diphtheria
132
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:25Transmission-based Precautions II: Airborne and Protective Environment
2.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
