History of measles.

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• Measles is a highly contagious airborne viral disease with significant mortality in developing countries.
• Complications include diarrhea, otitis, pneumonia, and encephalitis, primarily affecting young children.
• Historical accounts trace measles descriptions to the 10th century, with its viral nature confirmed in the 20th century.

Purpose of the Study:

• To provide a comprehensive overview of measles, encompassing its history, virology, epidemiology, and control.
• To highlight the impact of the measles vaccine on global public health.
• To underscore the ongoing public health challenge posed by measles worldwide.

Main Methods:

• Historical literature review for early descriptions and epidemiological studies.
• Virological analysis to identify the measles virus and its origins.
• Examination of vaccine development and global vaccination program data.

Main Results:

• Measles is caused by a morbillivirus, a human-adapted strain originating from rinderpest virus.
• A live attenuated measles vaccine, licensed in 1963, has proven highly effective.
• Despite vaccination, measles remains a major concern, causing over 100,000 deaths annually, particularly in Africa, South America, and Asia.

Conclusions:

• The measles vaccine has been instrumental in saving millions of lives and reducing disease burden globally.
• Continued efforts are needed to address measles as a significant public health issue, especially in vulnerable regions.
• Understanding measles's history and virology is crucial for ongoing disease control and prevention strategies.
