When was the first bacterial outbreak traced by genome sequencing?
Quick Answer
Genome sequencing was first used for outbreak tracing in the 1990s and 2000s. It became a powerful tool for tracking hospital and community infections.
The Full Story
The use of genome sequencing to trace bacterial outbreaks developed in the 1990s and became increasingly important in the 2000s. Researchers could compare the DNA of bacterial isolates to see how closely related they were and reconstruct transmission chains. This approach improved investigations of foodborne illness, hospital outbreaks, and public-health emergencies. It marked a major advance from older methods based only on culture and basic typing.
