1. What is Infectious Disease Tracker?
Infectious Diseases Tracker (previously known as Hotspot Tracker) is one of the functions available in the MySejahtera application to track COVID-19 cases in Malaysia. Now, the function has been enhanced to include more infectious diseases, namely (1) dengue fever, (2) rabies, (3) measles, (4) hand-foot-mouth disease (HFMD), and (5) tuberculosis.
2. How does Infectious Disease Tracker work?
Infectious disease tracker locates new cases reported by district health offices and state health departments. The locations of these new reported cases are mapped to display the numbers of active cases around any selected search point without disclosing the patients’ exact coordinates. Hence, users will be able to see the number of active cases for each disease reported within the radius from their point of search.
3. What are the radius and duration of active cases for each disease?
The radius and duration of active cases of the diseases are as the following:

4. What does it mean by radius for infection disease?
Radius for infectious disease is the detection area of all active cases from your point of search.
5. What does it mean by duration of active case for infectious disease?
The duration of active cases for infectious disease is the time frame in which the disease is in their infectious period, hence, shown in the Infectious Disease Tracker. This duration varies from one disease to another.
6. How should I respond to the presence of high active cases from my point of search?
Users can avoid high risk areas and take extra precautions whenever they are in these areas. Based on this information, high-risk individuals (children, elderly, immunocompromised) can avoid from going into areas with high number of active cases.
7. How should a community respond to the presence of high active cases in their area?
The community can arrange for cleaning campaign and alert each other by conveying the information to their social circle (e.g., WhatsApp group, Telegram channel, Facebook group etc) especially during social and religious gatherings.
8. Where can I get more information about the infectious diseases?
Users may refer to the following links for more information about each of the infectious diseases:
i) COVID-19 (Bahasa Malaysia | English)
ii) Dengue fever (Bahasa Malaysia | English)
iii) Rabies (Bahasa Malaysia | English)
iv) Measles (Bahasa Malaysia | English)
v) HFMD (Bahasa Malaysia | English)
vi) Tuberculosis (Bahasa Malaysia | English)
9. Do I need to turn on GPS location all the time?
Once you have given GPS permission to allow tracking, the app will automatically turn on GPS when necessary.
10. Does the GPS location require internet such as mobile data or Wi-fi?
GPS itself does not require an internet connection. However, the information about infectious diseases in your area is sent via the app and requires an internet connection.
11. How far can the GPS location detect cases around me?
The distance depends on the type of infectious disease. It ranges from a radius of 200 metres for dengue cases and up to a radius of 5 km for hand-foot-and-mouth disease.
12. How does the Infectious Disease Tracker map the coordinates of each case?
Using the reports from KKM, geolocation of infectious diseases is uploaded to the database without providing patient’s personal data.
13. If I arrive in my hometown somewhere in a remote area with poor internet connection, will GPS still be able to detect me?
GPS uses satellite technology and is able to determine your location or the requested location area. However, a stable internet connection is required to search for a location without using GPS and to view information.
14. Will the Infectious Diseases Tracker put my personal information at risk?
No, it will not. Any personal information of the patients or the GPS location of the individual (requester) will not be stored in our system.
15. Will my personal information, including my location, be disclosed?
No, it will not. Any personal information of the patients or the GPS location of the individual (requester) will not be stored in our system.
16. Will my phone battery drain faster when I turn on GPS?
MySejahtera will only be utilising the GPS upon requesting user's current location for mapping. Any other usage would not require GPS; therefore, your battery would not be constantly drained.
17. Will my exact location be disclosed to the people surrounding me when I turn on the GPS?
No, it would not. Any personal information of the patients or the GPS location of the individual (requester) will not be stored in our system.
18. What should I do if the displayed location is incorrect?
You might try searching for the area you are in, using terms like street name, district, and postcode in the search bar.
19. How long must the internet be turned on in order to utilise Infectious Disease Tracker?
A user would only use a small amount quantity of data over a brief period of time to obtain disease information near their location, and this would not be a continual activity.
20. Was it necessary to utilise mobile data for this app?
Most apps that send information will require the use of Wi-Fi or mobile data. Though it will be extremely minimal in this case.
21. Is it necessary for me to keep Bluetooth turned on at all times?
Bluetooth does not need to be turned on in order to use the Infectious Disease Tracker.
22. When I switch on Bluetooth on my device, will my privacy be protected?
To use the Infectious Disease Tracker, Bluetooth does not need to be turned on, and your privacy will be protected according to the app's privacy policy.
23. Will my phone overheat if I switch on Bluetooth?
Bluetooth will not need to be turned on in order to use the Infectious Disease Tracker. It will only use minimal amount of Wi-Fi or mobile data connection.
24. Will the usage of a smart watch that connects to a phone interfere with the use of an infection disease tracker?
25. If Bluetooth is not working, how can I connect to the infectious disease tracker?
Bluetooth does not need to be turned on in order to use the Infectious Disease Tracker. Only an internet connection is necessary, and GPS location data is optional if you want to utilise the search of your current location feature; alternatively, you can type your location into the search bar.
