What role do molecular techniques play in epidemiology?
Molecular techniques have revolutionized epidemiology by providing detailed insights into the genetic characteristics of pathogens. Techniques like PCR and sequencing allow for:
- Pathogen Identification: Rapid and accurate identification of pathogens at the molecular level. - Genetic Analysis: Understanding genetic variations and mutations that may affect virulence and resistance. - Phylogenetic Studies: Tracing the evolutionary history and relationships among different strains of a pathogen.
