‘We need to modify covid surveillance’
The government must modify the surveillance and testing strategies to track positive cases in the community after hospitalization and focus on testing in those particular areas in a mission mode, the public health experts added.
There’s a need to apply ‘epidemiological intelligence’ wherever the new covid variant XBB.1.16 is found spreading in India, top epidemiologists said, following a fresh spike in covid cases.
However, they said the covid scenario is different from what it was 2-3 years ago. Epidemiological Intelligence can be defined as the process to detect, verify, analyze, assess and investigate public health events that may represent a threat to public health.
Providing early warning signals is a main objective of public health surveillance systems. It encompasses activities related to early warning functions but also signal assessments and outbreak investigation.
