Measles (Rubeola): An Update
Abstract:
Measles is a significant concern with approximately 10 million people infected annually causing over 100,000 deaths worldwide. In the US before use of the measles vaccine, there were estimated to be 3 to 4 million people infected with measles annually, causing 400 to 500 deaths. Complications of measles include otitis media, diarrhea, pneumonia, and acute encephalitis. Measles is a leading cause of blindness in the developing world, especially in those who are vitamin A deficient. Malnourished children with measles are also at higher risk of developing noma (or cancrum oris), a rapidly progressive gangrenous infection of the mouth and face. Most deaths due to measles are caused by pneumonia, diarrhea, or neurological complications in young children, severely malnourished or immunocompromised individuals, and pregnant women. A rare sequela of measles is subacute sclerosing panencephalitis.
Insights
Measles infects 10 million globally each year, causing over 100,000 deaths. Complications like pneumonia and encephalitis pose significant risks, particularly for vulnerable populations.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Measles remains a major global health concern, with millions infected and over 100,000 deaths annually.
- In the United States, pre-vaccine measles incidence was 3-4 million cases per year, resulting in 400-500 deaths.
- Measles complications are diverse, including otitis media, diarrhea, pneumonia, acute encephalitis, and blindness, especially in vitamin A-deficient populations.
Purpose of the Study:
- To highlight the global burden of measles.
- To outline the severe complications associated with measles infection.
- To emphasize the mortality and morbidity associated with measles, particularly in vulnerable groups.
Main Methods:
- This abstract summarizes existing data on measles incidence, mortality, and complications.
- Information is drawn from global health statistics and historical US data.
- The focus is on describing the impact and sequelae of measles infection.
Main Results:
- Globally, measles affects approximately 10 million individuals annually, leading to over 100,000 deaths.
- Complications include pneumonia, diarrhea, acute encephalitis, and blindness.
- Severe malnutrition and immunocompromised states significantly increase the risk of mortality and severe complications like noma and subacute sclerosing panencephalitis.
Conclusions:
- Measles is a serious infectious disease with a substantial global impact.
- Prompt recognition and management of measles and its complications are crucial for reducing mortality and morbidity.
- Vaccination remains a critical strategy for controlling measles outbreaks and preventing severe outcomes.
