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...

Rh Blood Group

The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Summary

Costa Rica implemented targeted rubella vaccination campaigns for adults, significantly reducing congenital rubella syndrome (CRS) risks. This strategy protected child-bearing populations and informed regional elimination efforts.

Area of Science:

  • Public Health
  • Epidemiology
  • Vaccinology

Background:

  • Congenital rubella syndrome (CRS) is characterized by deafness, cataracts, and cardiac defects.
  • Rubella vaccination began in Costa Rica in 1972, with a combined vaccine introduced in 1986.
  • Previous vaccination strategies shifted susceptibility to child-bearing age groups.

Purpose of the Study:

  • To describe Costa Rica's experience in eliminating rubella and CRS.
  • To highlight successful vaccination strategies targeting adult populations.
  • To discuss challenges and strategies for rubella and CRS elimination.

Main Methods:

  • National rubella vaccination campaigns targeting individuals aged 15-39 years in 2001.
  • Postpartum vaccination for women pregnant during the campaign.
  • Strengthened epidemiological surveillance integrated with febrile eruptive disease reporting.

Main Results:

  • Successful national immunization campaign protecting child-bearing age groups.
  • Strengthened surveillance systems for rubella and CRS.
  • Costa Rican experience influenced similar actions in other Latin American countries.

Conclusions:

  • Targeted adult vaccination campaigns are effective in rubella and CRS prevention.
  • Integrated epidemiological surveillance is crucial for disease elimination.
  • Costa Rica's experience provides a model for regional rubella and CRS elimination strategies.
