Frequently asked questions (FAQ) on HIDE

Q What is HIDE?

A The Hotspot Identification for Dynamic Engagement (HIDE) is a Big Data analytics and AI system to predict specific MySejahtera premises that are at risk of becoming Covid-19 hotspots over the next seven days. Every day, HIDE will generate a list of such premises that will be published by the Health Ministry to facilitate self-regulation by the public and businesses.


A We observed that only 0.2% of premises registered on MySejahtera account for around 90% of Covid-19 transmissions in Malaysia. These insights help the relevant authorities to deploy enforcement resources better.

Q Are these premises actual clusters?

A No, these premises are potential cluster locations that are at risk of materialising should no corrective action be taken. They are not actual clusters that have been identified by the Health Ministry.

Q Who developed and manages HIDE?

A HIDE is developed and managed by the Crisis Preparedness and Response Centre (CPRC), a unit under the Health Ministry, which comprises officers from various ministries and government agencies. All data pertaining to HIDE is owned by the Health Ministry.

For the premises owner

Q Why did my premises appear on HIDE?

A Based on backward and forward contact tracing using MySejahtera check-in data, a sizeable number of individuals potentially exposed to Covid-19 positive individuals have visited your premises.

Q If HIDE flags my premises, do I need to shut down my premises?

A No, you do not need to shut down, unless required by enforcement authorities. However you are advised to quickly undertake pre-emptive actions, including:

> Enhance gatekeeping (deny entry of individuals with ‘high-risk’ MySejahtera status)

> Screen your workers for Covid-19

> Tighten crowd control measures

Q How long should I take pre-emptive actions for?

A The seven days after your premises is listed on the HIDE list are crucial (Day 1 begins when your premises is listed on HIDE). These pre-emptive actions are best practices to prevent the spread of Covid-19

Q How do I get my premises off the HIDE list?

A If there are no hotspots materialising at your premises arising from pre-emptive actions, your premises will likely be off the list within seven days of publication. We will publish a daily list of premises that have been taken off the HIDE list. There is a possibility of a premises being listed on the HIDE list more than once, which is usually an indication that controls have been inadequate.

For the public

Q What should I do with the HIDE list that is published daily?

A The daily publication of the list aims to empower the public to make informed decisions on their movement and conduct.

Q I have visited premises flagged by HIDE, what should I do?

A If you have visited the premises within seven days after the premises was flagged by HIDE, you are encouraged to isolate yourself, minimise further contact with others, and monitor yourself for any symptoms. If you develop symptoms over the next 14 days, you are advised to take a Covid-19 test at your nearest health screening facility.
