It is a public-domain CSR with National Institute of Health to help monitor the spread of COVID-19.

Data Sources

Map Data Last Updated: 01/01/2024
14-day active cases data is sourced from mysejahtera app through api lookup. Contact the author for info about how to extract data from mysejahtera.
Note:

• Since 13/01/2023, the MYsejahtera query response has returned all zeros for Covid-19 cases nationwide. It is impossible that a infectious disease can just suddenly vanish into thin air.
• Upon closer inspection, there is a likelyhood that the Covid-19 data column was mixed up with HFMD or TB which suddenly showed a widespread coverage.
• In order to assess the nature of the problem, I have collected raw data of several smaller areas in json format for analysis.
• Below are the links to the some of the smaller json output for comparison with the corresponding csv files for side by side comparison:
  • 20230118 KL Raw Data - 20230118 KL csv file
  • 20230118 Putrajaya Raw Data - 20230118 Putrajaya csv file
  • 20230118 Labuan Raw Data - 20230118 Labuan csv file
• It turns out that there is a possibility that the Mysejahtera programmer has accidentally swapped the data columns. It certainly reflects very bad on a software purportedly worth more than RM 70 million!
• I am now doing a trial on error by swapping the columns with most active cases, i.e. HFMD and TB columns with the Covid-19 column for the csv datasource from 18/1/2023 onwards.

• If the map output looks peculiar, please let me know. Thank you very much.

• Map data from 09/05/2022 to 08/07/2022 were all zeroes due to the old hotspots interface API location https://mysejahtera.malaysia.gov.my/register/api/nearby/hotspots?type=locateme being superceded by https://mysejahtera.malaysia.gov.my/epms/v1/hotspot/nearby?type=locateme
  
• The request json is still the same

  [{
  "lat" : "3.0926898",
  "lng" : "101.7342783",
  "classification":"LOW_RISK_NS"
  }]
  

• However, the old json response:

  {"hotSpots":[],"zoneType":"GREEN","messages":{"ms_MY":"Hai {name}, tiada kes COVID-19 dalam lingkungan radius 1km dari lokasi ini yang dilaporkan dalam masa 14 hari yang lepas.","en_US":"Hi {name}, there have been no reported case(s) of COVID-19 within a 1km radius from your searched location in the last 14 days."},"note":null} 
  

  is now superceded by a new version with the following format in Mysejahtera ver 2.x.x :
  

  {"hotSpots":[
  {"disease":"COVID-19","displayName":{"enUS":"COVID-19","msMY":"COVID-19"},"iconUri":"/hotspot/icons/COVID19.svg","activeCases":31,"radiusInMeters":1000.0,"durationInDays":14}, 
  {"disease":"DENGUE","displayName":{"enUS":"Dengue","msMY":"Denggi"},"iconUri":"/hotspot/icons/dengue.svg","activeCases":0,"radiusInMeters":200.0,"durationInDays":14}, 
  {"disease":"RABIES","displayName":{"enUS":"Human Rabies","msMY":"Rabies dalam manusia"},"iconUri":"/hotspot/icons/rabies.svg","activeCases":0,"radiusInMeters":1000.0,"durationInDays":90}, 
  {"disease":"MEASLES","displayName":{"enUS":"Measles","msMY":"Demam Campak"},"iconUri":"/hotspot/icons/measles.svg","activeCases":0,"radiusInMeters":1000.0,"durationInDays":25}, 
  {"disease":"HFMD","displayName":{"enUS":"Hand, Foot & Mouth Disease","msMY":"Penyakit Tangan, Kaki & Mulut​"},"iconUri":"/hotspot/icons/HFMD.svg","activeCases":3,"radiusInMeters":5000.0,"durationInDays":7}, 
  {"disease":"TB","displayName":{"enUS":"Tuberculosis","msMY":"Tibi"},"iconUri":"/hotspot/icons/TB.svg","activeCases":1,"radiusInMeters":1000.0,"durationInDays":60}, 
  {"disease":"ANIMAL_RABIES","displayName":{"enUS":"Animal Rabies","msMY":"Rabies dalam haiwan"},"iconUri":"/hotspot/icons/rabiesCircle.svg","activeCases":0,"radiusInMeters":5000.0,"durationInDays":180} 
  ]}
  

  
  Warning:
  The old API will still respond to requests, but it will not give you the correct no of cases for each lookup (all zeroes!).
  This would also mean that the hotspots lookup feature will not work on older versions of mysejahtera mobile app (v 1.0.x to 1.1.8).
  
  

Latest Mysejahtera json format as of 27/9/2022 (changes in the sequence of elements):

{"hotSpots":[
{"disease":"RABIES","displayName":{"enUS":"Human Rabies","msMY":"Rabies dalam manusia"},"iconUri":"/hotspot/icons/rabies.svg","activeCases":0,"radiusInMeters":1000.0,"durationInDays":90},
{"disease":"TB","displayName":{"enUS":"Tuberculosis","msMY":"Tibi"},"iconUri":"/hotspot/icons/TB.svg","activeCases":0,"radiusInMeters":1000.0,"durationInDays":60},
{"disease":"DENGUE","displayName":{"enUS":"Dengue","msMY":"Denggi"},"iconUri":"/hotspot/icons/dengue.svg","activeCases":0,"radiusInMeters":200.0,"durationInDays":14},
{"disease":"ANIMAL_RABIES","displayName":{"enUS":"Animal Rabies","msMY":"Rabies dalam haiwan"},"iconUri":"/hotspot/icons/rabiesCircle.svg","activeCases":0,"radiusInMeters":5000.0,"durationInDays":180},

Note:

1. The javascripts are minified and obfuscated for faster performance. Kindly email me on the link below if you wish to have the raw code.
2. Some maps may be too large (Sarawak, Sabah, Pahang) and hence the performance and display on the client side will be extremely slow, particularly when the markers are enabled. A server side clustering solution is available.
