Molecular epidemiology refers to the study of the distribution and determinants of diseases in populations using molecular biology tools. Some synonyms for this term include genomic epidemiology, molecular diagnostics, and molecular pathology. Genomic epidemiology involves the use of genomic sequencing to understand how pathogens spread and evolve. Molecular diagnostics are used to diagnose infections and genetic diseases by analyzing the DNA or RNA of the patient. Molecular pathology involves the study of the molecular mechanism behind diseases, which helps in identifying and treating illness. These synonyms highlight the importance of molecular techniques in understanding the epidemiology of diseases and developing effective treatments.
