PCR is widely used in epidemiology for several purposes:
Pathogen Detection: PCR allows for the rapid and accurate identification of pathogens in clinical and environmental samples. Genotyping: This helps in understanding the genetic variation among pathogen strains, which is essential for tracking disease outbreaks. Drug Resistance: Amplifying DNA can help identify genetic markers associated with resistance to antibiotics or antiviral drugs. Epidemiological Surveillance: PCR is used to monitor the spread of infectious diseases over time and across different geographical regions.
