Respiratory Syncytial Virus Disease

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...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

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...

Smallpox

Smallpox

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.

Area of Science:

Public Health
Immunology
Pediatrics

Background:

Measles is a leading cause of childhood mortality in low and middle-income countries.
Measles immunization is a highly cost-effective public health strategy.
Needle-free immunization methods are sought for mass vaccination campaigns.

Purpose of the Study:

To review clinical trials on aerosol measles vaccine administration.
To assess the safety, immunogenicity, and logistical feasibility of this novel delivery route.
To evaluate vaccine strain, presentation, and manufacturer considerations.

Main Methods:

Review of clinical trials involving aerosol measles vaccine delivery.
Analysis of data on vaccine safety and immunogenicity in different age groups.
Assessment of logistical aspects for mass campaigns and routine immunization.

Main Results:

Aerosol measles vaccine administration is safe and immunogenic in infants and school-aged children.
Higher viral inoculum may be required for infant immunization.
Feasibility demonstrated in mass campaigns, with potential for cost savings.

Conclusions:

Aerosol measles immunization is a viable, needle-free alternative for public health.
Further evaluation for routine immunization and regulatory approval is ongoing.
This method holds potential for improving global measles control efforts.
