Deep dives
The Historical Origins of Measles
Measles is believed to have originated from a now-extinct disease in cattle known as Rinderpest, which likely jumped to humans thousands of years ago due to increased interaction between humans and livestock. This zoonotic transfer enabled the virus to establish itself exclusively within the human population, leading to widespread outbreaks. Initially, measles was viewed as a normal childhood illness, but over time, its severe complications have become well-documented, including pneumonia and encephalitis, highlighting its potential lethality. Understanding the historical context of measles helps illustrate the importance of vaccination in preventing the resurgence of this disease.
