Diagnosing past infections: A review

Area of Science:

• Paleopathology
• Paleomicrobiology
• Genomics

Background:

• Understanding historical health challenges is crucial for medical research.
• Early diagnosis relied on observational evidence, skeletal remains, and historical records.
• Past outbreaks like the Black Death and smallpox offer insights into disease impact.

Purpose of the Study:

• To review the evolution of diagnostic methods for ancient infectious diseases.
• To highlight emerging diagnostic techniques and their applications.
• To explore the potential of new technologies and interdisciplinary collaboration.

Main Methods:

• Paleopathological analysis of bones and tissue lesions.
• Molecular and serological techniques (PCR, serology, immunodetection) for paleomicrobiology.
• Next-generation sequencing and metagenomics for pathogen genome retrieval.

Main Results:

• Significant advances in diagnosing ancient infectious diseases.
• Identification of ancient pathogens through DNA and antibody detection.
• Retrieval of ancient pathogen genomes from various preserved samples.

Conclusions:

• Next-generation sequencing and metagenomics are revolutionizing ancient disease diagnosis.
• Interdisciplinary collaboration is key to future breakthroughs.
• New techniques like paleocytology and mass spectrometry offer novel diagnostic avenues.
