Summary
Significant progress has been made in reducing measles transmission in the Eastern Mediterranean Region (EMR) through increased vaccination coverage and surveillance. However, challenges remain, preventing the region from achieving measles elimination by 2010.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- The Eastern Mediterranean Region (EMR) adopted a goal to eliminate measles transmission by 2010.
- Substantial progress has been observed since the goal's adoption in 1997.
Purpose of the Study:
- To assess the progress made toward measles elimination in the EMR.
- To identify remaining challenges hindering the achievement of measles elimination.
Main Methods:
- Analysis of routine measles-containing vaccine (MCV) coverage rates.
- Review of measles catch-up and follow-up vaccination campaigns.
- Evaluation of case-based measles surveillance systems with laboratory confirmation.
- Assessment of reported measles cases and mortality data.
Main Results:
- Routine MCV first-dose coverage increased from 70% (1997) to 82% (2009) across 22 EMR countries.
- Reported measles cases decreased by 86% (1998-2008), and estimated mortality by 93% (2000-2008).
- The EMR contributed 17% to global measles mortality reduction during 2000-2008.
Conclusions:
- Despite significant reductions in measles cases and mortality, the EMR will not achieve elimination by 2010.
- Key challenges include maintaining high population immunity with two MCV doses, enhancing surveillance sensitivity, and targeting high-risk groups for vaccination.
- Effective outbreak response remains crucial for achieving and sustaining measles elimination.

01:17Poliomyelitis
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...
01:24Smallpox
Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.

01:29Respiratory 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...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
01:29Malaria
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...
