Insights

The 2009 Influenza A (H1N1) pandemic primarily impacted children in Panama, showing a low fatality rate. This strain was the dominant circulating influenza virus during the 2009-2010 season.

Area of Science:

  • Epidemiology
  • Infectious Diseases
  • Public Health

Background:

  • Pandemic Influenza A (H1N1) emerged as a significant global febrile respiratory illness in 2009.
  • This study details the clinical and epidemiological features of the H1N1 outbreak in Panama.

Purpose of the Study:

  • To characterize the clinical and epidemiological aspects of the 2009 Influenza A (H1N1) pandemic in Panama.
  • To analyze affected age groups, geographical distribution, and outcomes.

Main Methods:

  • A descriptive study utilizing data from the Gorgas Memorial Institute.
  • Included patients with severe acute respiratory infection confirmed positive for 2009 Influenza A (H1N1) via RT-PCR.

Main Results:

  • 806 confirmed cases from April 2009 to January 2010, with an incidence rate of 23.35 per 100,000.
  • Highest incidence in the 10-14 age group; median age was 13 years.
  • Fever and cough were predominant symptoms; case fatality rate was 0.3 per 100,000.

Conclusions:

  • The 2009 Influenza A (H1N1) outbreak in Panama predominantly affected the pediatric population.
  • The pandemic strain exhibited a low case fatality rate.
  • Influenza A (H1N1) was the primary circulating influenza virus during the 2009/2010 season in Panama.

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 Occurrence01:28

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...
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...
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
