We reported a case of measles with diarrhea in an infant. Capsule biopsy samples of intestinal mucosa taken 14 days after onset of fever was damaged and had low disaccharidase activities. Virus particles were found in the damaged villous cell. Second intestinal mucosa biopsy samples taken 28 days after onset of fever was found to be normal in structure, but lactase and sucrase activities were still low. Mucosal damage by virus particles was the cause of diarrhea in our infant.

The European cattle was domesticated 10 000 years ago in eastern Turkey, 1000 years later pottery-associated milk fats identify cattle-based dairy activity in western Turkey. Subsequently, the Indo-European language, domesticated animals and plants travel as a Neolithic package along two major routes across Europe. A striking south-east to north-west gradient of a mutation in the current European population (lactase persistence into adulthood) documents the expansion of a Neolithic dairy culture into a Mesolithic hunter society. Using oral tradition (myths), archaeological and written historical evidence and biological data, it is asked whether highly transmissible viral diseases like measles and smallpox entered during the Neolithic from domesticated animals into the human population. The bovine origin of paramyxovirus infections is likely; smallpox comes from camels or from rodents via cattle while mycobacteria and Helicobacter infected humans already before the Neolithic. Microbes adapt constantly and quickly to changing ecological situations. The current global environmental changes will lead to another highly dynamic phase of viral transmissions into the human population.
