The child mummy was found in a wooden coffin with the outermost lime–soil mixture barrier intact. The Child Mummy of Yangju is extremely important towards the progress of research on the Ancient Hepatitis B Virus. The child mummy's biopsy revealed that the child had HBV-C2. HBV has a high mortality rate even today, so any further analysis is well documented.
The child was naturally mummified.
Endoscopic exams found that well-preserved internal organs remained within the thoracic, abdominal and cranial cavities. The internal organs – including the brain, spinal cord, lung, muscles, liver, heart, intestine, diaphragm and mesentery – were investigated. a heart remnant was found within the thoracic cavity, although it was notably shrunken. Unusual nodules were found on the surface of the intestines and liver. the nodules might have been caused by unknown pathological changes resulting from tuberculosis or hydatid disease, but it's unclear.
Studies done compare the Ancient Hepatitis Virus with the modern one. It has provided more insight on the genomes and development of the infection.
The first full viral genome of Hepatitis B Virus was extracted from the child mummy. The complete sequence obtained probably represents a wild‐type HBV pathogen without precore mutations, which infected the population during the Joseon Dynasty in Korea approximately 400‐500 years ago. Based on analysis, the virus most probably originated in China or Japan and spread to Korea.
