Which border districts reported outbreaks, and what a unit should prepare for before it deploys.

NCDC publishes India's outbreak record as one PDF a week. The report for 17 to 23 August 2026 lists 48 outbreaks (44 reported that week, 4 filed late from earlier weeks), including measles in Dhubri on the Bangladesh border (6 cases) and dengue in Samba on the Pakistan border (10 cases) (IDSP week 34, 2026). It was published on 13 October, 51 days after that week ended.

A medical officer preparing a team for a border district has to piece the picture together from dozens of these tables, each listing outbreaks across all of India, with no view by district, border or season, and no link to what to do about it.

• An outbreak board for the 194 districts on a land border or the coast: a map, the list of outbreaks with a link to the exact page of each IDSP report, and counts by neighbouring country.
• A record for every district of India: each outbreak since January 2025, outbreaks within 100 km, the state's recent pattern and WHO notices from across the border.
• Disease seasons that are tested, not guessed: a season is named only when outbreaks cluster in it more than in 99 of 100 random reshuffles. Japanese encephalitis in Assam peaks in June and July; dengue in Jammu and Kashmir from August to October.
• A pre-deployment brief for any district and month that prints on A4: recent outbreaks in and around the district, seasonal risks, notices from neighbouring countries and preventive measures summarised from WHO, the National Center for Vector Borne Diseases Control and CDC, with numbered sources.

1. Fetch. Download each weekly PDF from NCDC once, politely, and keep a cached copy.
2. Read. Rebuild the tables from word positions on the page, rejoin words wrapped inside narrow cells, and drop the comments column, which can describe patients.
3. Check. IDSP ids end in a running serial; in 83 of 86 reports the parsed serials form an unbroken run, and the PDFs themselves explain the rest. Two more checks catch errors in the PDFs themselves: a report assembled from an earlier week's file (as published in October 2026, the 2026 week 30 report repeats week 29's cases, dates and comments in 46 rows; those rows are kept without the copied figures) and an outbreak listed twice.
4. Place. Match every row to one of 792 current districts from Wikidata (proposed and former districts left out); flag land-border districts from OpenStreetMap, with four cited additions, and coastal districts from the CMFRI fisheries census.
5. Count and test. Count outbreaks by district, report window and month of onset; test each disease for a season.
6. Publish. Write JSON files with a manifest of sources and retrieval times. Briefs are assembled in the browser, so a chosen district never leaves the page.

Every rule, check and limit is on the methods page (console sign-in).

Medical officers of units posted to border and coastal districts decide what to check, carry and brief before a move. Unit commanders read the brief with them. State IDSP cells and district surveillance units see their own record next to their neighbours' and across the border.

• Aggregate counts only. Each record is an outbreak in a district, never a person, and the comments column of the reports is never read into the data.
• Arogya never links an outbreak to migrants, nationality, religion or any community, and offers no filter by any of them. WHO titles are cut to disease and country.
• Advisory. Every page and brief says to follow NCDC/IDSP, the state health department, the district surveillance unit and the unit medical officer, and WHO for neighbouring countries.
• Every number carries its source and time; the method, checks and limits are published.

• Reports reach the public seven to eight weeks after the week they describe. For current alerts, ask the district surveillance unit.
• Reporting is incomplete: in a typical week about half of the 36 States/UTs file a report. No outbreak listed does not mean none occurred.
• IDSP lists outbreaks that states investigated, not all cases; endemic diseases such as malaria are mostly reported through other programmes.
• Seasons rest on about twenty months of reports. They describe the reports, not a forecast.
• Border flags follow OpenStreetMap plus four cited additions where its district outlines stop short of the boundary; map boundaries are not authoritative.
