Measuring the dose of a pathogen can be complex and involves several methods: 1. Quantitative PCR (qPCR): This molecular technique quantifies the amount of pathogen DNA or RNA in a sample. 2. Culture Methods: These methods involve growing the pathogen in a laboratory setting to estimate its concentration. 3. Epidemiological Studies: Observational studies can provide indirect estimates of pathogen dose based on exposure history and infection rates.
