This belonged to a two-year-old child who was initially believed to have been suffering from smallpox. However, they decided to perform a genetic analysis and discovered the actual cause of death was hepatitis B. This proves the disease has been around for more centuries than we thought.
The mummy had actually died of hepatitis B

Researchers discovered the mummy between 1983 and 1983, and saw it was covered in some strange marks which resembled smallpox. After studying the marks, they discovered traces of smallpox particles in them, so they assumed this was the cause of death.

Researchers couldn’t tell how early the disease appeared, and this would have been the oldest evidence of its presence in the Medieval world. However, it turned out it wasn’t actually smallpox that killed the boy.
Hepatitis B left marks on the body similar to those of smallpox

Hepatitis B is an infection of the liver but, if small children contract it, they are left with similar marks on the face, legs, arms, and bottom. On all these areas, the mummy showed blisters.

This way, they concluded that, during mummification, the virus might have been altered and took an unrecognizable form. Also, this explains why they mistook the virus for Variola at first (the virus that causes smallpox).
