IHIP Reporting Schedule: Epidemiological Week, Deadlines and Zero Reporting
IDSP counts time in reporting weeks that run Monday to Sunday. On IHIP you enter cases daily, but performance is judged week by week. This page explains the week, today's routine, the older paper deadlines and zero reporting.
- IDSP reporting week
- Monday to Sunday (IDSP Form Guidelines)
- Entry on IHIP
- Every day, per the IHIP P form user manual
- Performance review
- Weekly S, P and L form reporting (e.g. NHM Assam 2024 to 26)
- Lab results
- Enter within 7 days of testing (IHIP manuals)
- Older paper deadlines
- Sub-centre by Monday, PHC/CHC to district by Tuesday (historical)
- Week numbers
- Match ISO weeks in reports we checked (our observation, not an official rule)
Surveillance only works if everyone counts time the same way. IDSP, the Integrated Disease Surveillance Programme, uses a reporting week (साप्ताहिक रिपोर्टिंग सप्ताह) that runs from Monday to Sunday. Weekly outbreak reports from NCDC are labelled by week number, such as the "49th week" of 2025.
Since the move to the Integrated Health Information Platform (IHIP), the rhythm has changed. Cases are entered daily and case by case, yet reporting performance is still measured weekly. This guide sets out what the official sources say, separates current guidance from older paper-era deadlines, and is clear about where we are making our own observation. If you need to find a week number quickly, use the epidemiological week calendar at the top of this page. This site is an independent guide, not an official MoHFW or NCDC page.
The IDSP week: Monday to Sunday
The older IDSP Form Guidelines and the IDSP training manual for paramedical staff both describe weekly reporting on a Monday to Sunday basis. A case seen on Sunday belongs to the week that started the previous Monday. A case seen on Monday starts a new week.
NCDC's weekly outbreak reports use this same week. For example, the report for the 49th week of 2025 covers 1 to 7 December 2025, and the 18th week of 2021 covered 3 to 9 May 2021. Both run Monday to Sunday.
We found no official IDSP document that defines the term "epidemiological week" itself. Official material talks about the reporting week. On this site we use the two terms for the same Monday to Sunday week.
How week numbers are counted: our observation
No official IDSP or IHIP document we found states a rule for which week is week 1 of the year. What follows is our observation, not an official rule.
We compared the dates in official weekly outbreak reports with the ISO 8601 week calendar, in which week 1 is the week that contains the first Thursday of the year. Every check matched:
| Official report | Dates in the report | ISO week for those dates |
|---|---|---|
| 18th week 2021 | 3 to 9 May 2021 | Week 18 |
| 49th week 2025 | 1 to 7 December 2025 | Week 49 |
| Week 27, 2026 (NCDC outbreak count) | Ends 5 July 2026 | Week 27 |
So the week numbers on our calendar follow the ISO system. That fits every official report we checked, but your state or district may have its own instruction. If a district circular gives a different week number, follow the circular and tell us so we can review the calendar.
हिंदी में सारांश
IDSP का रिपोर्टिंग सप्ताह सोमवार से रविवार तक चलता है। IHIP पर P फॉर्म मैनुअल के अनुसार डेटा रोज़ भरना है, लेकिन प्रदर्शन साप्ताहिक रूप से देखा जाता है। लैब परिणाम जांच के 7 दिन के भीतर दर्ज करें, और बीमारी शुरू होने की तारीख रिपोर्टिंग तारीख से 30 दिन के भीतर होनी चाहिए। पुराने कागज़ी नियम (उप केंद्र सोमवार तक, PHC/CHC मंगलवार तक DSU को) अब ऐतिहासिक हैं। सप्ताह संख्या ISO कैलेंडर से मेल खाती है, यह हमारा अवलोकन है, कोई आधिकारिक नियम नहीं: सप्ताह 18, 2021 = 3 से 9 मई 2021; सप्ताह 49, 2025 = 1 से 7 दिसंबर 2025। प्रकोप रिपोर्टिंग में NIL रिपोर्ट भी ज़रूरी है। S, P, L फॉर्म में शून्य रिपोर्टिंग का तरीका अपने जिला निगरानी इकाई से पूछें। 2025-26 में रिपोर्टिंग दर: S 78.31%, P 82.01%, L 83.40%। यह साइट सरकारी नहीं है।
Daily entry on IHIP, weekly performance
The biggest change from the paper era is timing. The IHIP P form user manual says users are expected to enter data every day. Reports for State Surveillance Officers show day-wise status for the last two weeks and week-wise status beyond that. Meanwhile the NHM Assam IDSP operational guideline for 2024 to 26 still lists performance as weekly reporting of the S form, P form and L form.
In short: enter every day, get judged every week. Other timing rules from the IHIP manuals:
- Lab results should be entered within 7 days of testing.
- The date of onset should fall within 30 days before the reporting date.
- Back-dated entry is discouraged.
This is why searches for an "IHIP daily report" are common. There is no separate daily report form in the sources we checked; daily entry simply feeds the weekly picture. Form-wise details are in the S form, P form and L form guides.
Older paper deadlines (historical guidance)
Before IHIP, IDSP reports moved on paper up a fixed weekly chain. These deadlines come from the older IDSP Form Guidelines. They are historical and may not match what your district expects today on IHIP. We have not found an official current deadline for IHIP.
| Who | Sent to | Older deadline |
|---|---|---|
| Sub-centres | PHC/CHC | By Monday |
| PHC/CHC and urban units | District Surveillance Unit (DSU) | By Tuesday |
| L1 labs (PHC/CHC) | MO by Monday, DSU by Tuesday | Monday / Tuesday |
| L2 and L3 labs | DSU directly | Every Tuesday |
| DSU | Data entry and analysis | By Thursday |
| DSU | Action and feedback | By Friday |
Reviewing the past week on Monday and Tuesday can still be a useful habit. Treat it as a habit, not a rule, unless your DSO says otherwise.
Zero reporting (nil reports): what is official
Zero reporting means sending a report even when there are no cases, so the district knows you checked. The official position is clearest for outbreaks. NCDC says "Nil reports are also required" for outbreak reporting, and the IDSP Early Warning Signal format says the State Surveillance Unit reports instantaneously and also sends a weekly compilation "on every Monday to the CSU including NIL reports". The NCDC IDSP page also states "Even NIL weekly reporting is mandated".
We did not find an IHIP manual that explains how to record a nil week on the S, P or L form screens. Confirm with your district surveillance unit how your unit should show a week with no cases. Never leave a week blank without telling your MO or DSU. For outbreak alerts, see the outbreak reporting guide.
A weekly routine that keeps you on schedule
- Monday morning: use the calendar to note the new week number and the dates it covers.
- Every working day: sign in on the official IHIP portal and enter that day's cases on your form. Do not save them for the weekend.
- Labs: enter results within 7 days of testing, so P form cases close properly.
- Any day: if you see unusual numbers or deaths, raise an Event Alert and phone your DSO. Do not wait for the week to end.
- Sunday or Monday: review your entries for the week just ended and fix gaps while still allowed. Remember back-dated entry is discouraged.
- If the week had no cases: follow your district's instruction for nil reporting.
- Check performance: ask your MO or DSU about your unit's weekly reporting status.
Your role decides which steps apply. See IHIP user roles.
How the country is doing on weekly reporting
NCDC publishes reporting rates. For 1 April 2025 to 31 March 2026 they were: S form 78.31%, P form 82.01% and L form 83.40%. In 2025 there were 184,895 S form reporting units (77% reported), 43,180 P form units (81%) and 36,414 L form units (82%).
The S form, filled at sub-centre level, has the lowest rate of the three, which is one reason daily mobile entry matters. If you are new to the programme, our IDSP explainer and the IHIP portal guide give the bigger picture.
Frequently asked questions
What is an epidemiological week in IDSP?
IDSP uses a reporting week that runs from Monday to Sunday, as set out in the older IDSP Form Guidelines and paramedical training manual. Weekly outbreak reports are labelled by this week, for example the 49th week of 2025 covering 1 to 7 December 2025. We found no separate official definition of the term epidemiological week.
How do I find the current epidemiological week number?
Use the calendar on this page. Its numbers follow the ISO 8601 system, where week 1 contains the first Thursday of the year. That is our observation from matching official weekly outbreak reports, not a written IDSP rule. If your district circular gives a different number, follow the circular.
Is IHIP reporting daily or weekly?
Both. The IHIP P form user manual says users are expected to enter data every day, and state reports show day-wise status for the last two weeks. Performance is still reviewed as weekly S, P and L form reporting, as in the NHM Assam guideline for 2024 to 26.
What is the IDSP reporting deadline?
Under the older paper system, sub-centres reported to the PHC or CHC by Monday, and PHCs, CHCs and urban units reported to the district by Tuesday. That is historical guidance. We have not found an official current deadline for IHIP, so follow daily entry and your DSO's instructions.
Is zero reporting required in IDSP?
For outbreaks, yes: NCDC says nil reports are also required, and the Early Warning Signal format asks for a weekly compilation every Monday including NIL reports. We did not find IHIP manual text on how to record a nil week on S, P or L forms, so confirm the method with your district surveillance unit.
Can I enter last week's cases late on IHIP?
The IHIP manuals discourage back-dated entry and require the date of onset to be within 30 days before the reporting date. Lab results should be entered within 7 days of testing. If you missed entries, enter them as soon as possible and inform your MO or DSU rather than leaving gaps.
