How often should HAVS screening be carried out?

HAVS surveillance is usually repeated at regular intervals to detect change over time.

Typical intervals

Baseline — before exposure begins
Annual — routine monitoring
Earlier — if symptoms reported

The purpose is to identify change early rather than diagnose disease.

Why repeated screening matters

HAVS develops gradually. Monitoring over time allows exposure to be adjusted before permanent symptoms occur.

Most workers remain within routine surveillance throughout employment without requiring further assessment.

Setting up surveillance

You can run screening across a workforce using a structured questionnaire.
