What is Genomic Surveillance and How Does It Work?
Genomic surveillance is the process of studying virus genetic material (RNA or DNA) to identify changes or mutations. By comparing virus genomes over time, scientists can detect new strains and predict their impact.
Steps in Genomic Surveillance to Identify New Virus Strains
Collecting Samples from Infected Individuals
- Health agencies collect virus samples from patients through swabs, blood tests, or wastewater monitoring.
Sequencing the Virus Genome to Identify Mutations
- Scientists use advanced machines to decode the virus’s genetic structure and identify changes.
Comparing New Virus Strains with Existing Ones
- The genetic sequences are compared with older virus versions to check for new mutations.
Tracking Virus Spread and Potential Risks
- If a mutation makes the virus spread faster or resist vaccines, health organizations take immediate action.

Why is Genomic Surveillance Important in Public Health?
Genomic surveillance is critical in pandemic preparedness and virus tracking. It helps:
- Detect new virus variants early before they become widespread.
- Develop updated vaccines by identifying key mutations.
- Guide public health policies to control outbreaks.
- Understand how viruses evolve over time and their potential risks.
