Dengue confirmed by NS1 antigen or IgM ELISA is notified in India through which form of the Integrated Disease Surveillance Programme (IDSP)?

• A L (laboratory) form after confirmation ✓
• B P (presumptive) form by community health workers
• C S (syndromic) form by primary health care physicians
• D Dengue is not a notifiable disease under IDSP

Explanation

IDSP uses a three-tier surveillance system: P-form (community/presumptive data by ASHAs and AWWs), S-form (syndromic/clinical data by clinicians at health facilities), and L-form (laboratory-confirmed data). Dengue requires laboratory confirmation — NS1 antigen (early), IgM ELISA (after day 5), or PCR — before mandatory notification via the L-form to district and national surveillance systems. Syndromic clusters may be flagged via S-form but definitive national reporting is L-form.
