Insights

In 2004, Poland recorded over 773,000 influenza cases, with children under 15 most affected. The study details regional incidence, hospitalizations, and identifies circulating influenza virus strains.

Area of Science:

  • Epidemiology
  • Virology

Context:

  • Influenza surveillance in Poland during 2004.
  • Analysis of regional incidence and demographic impact of influenza.

Purpose:

  • To report the epidemiological and etiological characteristics of influenza in Poland for 2004.
  • To detail influenza virus strains isolated and their antigenic properties.

Summary:

  • A total of 773,234 influenza cases were registered in Poland in 2004, with incidence varying regionally. Children under 15 represented 34.5% of cases.
  • Hospitalization was required for 0.20% of patients, and 52 deaths were attributed to influenza, predominantly in individuals over 70 years old.
  • Forty-nine influenza virus strains were isolated, including subtypes A/H1, A/H3, and type B, showing similarity to established reference strains. Other respiratory viruses were also detected.

Impact:

  • Provides crucial data for public health strategies and influenza prevention in Poland.
  • Highlights the significant burden of influenza, particularly in pediatric populations and the elderly.
  • Informs vaccine strain selection and understanding of circulating influenza strains.

Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Infectious Diseases and Their Occurrence

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 temporal or...
Acute Pharyngitis01:30

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
