MySejahtera was developed by Entomo Malaysia (formerly KPISoft Malaysia), a local developer founded by Anuar Rozhan and Raveenderan Ramamoothie, On 19 November 2020, Director General
Noor Hisham Abdullah confirmed that 9,167 COVID-19 cases had been identified by the MySejahtera app since its launch in April 2020 via
contact tracing methods including local district health offices using MySejahtera's database and the tracking of potential close contacts of COVID-19 patients. By 27 August 2021, 1.9 million of the 2.32 million students aged between 12 and 17 years enrolled at Malaysian national schools worldwide had registered for COVID-19 vaccinations via the MySejahtera app. In early November 2021,
Health Minister Khairy Jamaluddin stated that the MySejahtera app would not be used for moral policing in response to
Leader of the Opposition Anwar Ibrahim's claim that the MySejahtera app showed Muslims checking into gaming outlets. On 7 November 2021, the MySejahtera app experienced a glitch that caused it to incorrectly issue the "home surveillance order" (HSO) and "person under surveillance" (PUS) statuses to several users. The app's administrators apologised to the public for the panic they caused. That same day, the United States Embassy in
Kuala Lumpur confirmed that Malaysians travelling to the US could show their proof of vaccination on the MySejatera app, as well as a negative COVID-19 test. On 27 April 2022,
Health Minister Khairy Jamaluddin announced that scanning the MySejahtera QR code when entering premises is no longer compulsory beginning 1 May 2022. According to data released by the Health Ministry's
GitHub portal, MySejahtera app usage had plunged 73.8% by 3 May. On 26 May 2022, Khairy Jamaluddin announced that, in light of the
2022 monkeypox outbreak, MySejahtera users coming from countries with reported cases of
monkeypox would be sent an alert on the MySejahtera app starting 27 May 2022. This was done to prevent an outbreak of monkeypox in Malaysia. On 10 August 2023, the Malaysian
Health Ministry and
Election Commission confirm that COVID-19 positive votes will receive guidelines via the MySejahtera app on how to fulfill their voting responsibilities during the
2023 Malaysian state elections. On 5 July 2024, the Health Ministry ended its policy of requiring COVID-19 positive individuals to report their COVID-19 self-test results to the MySejahtera app. ==Contact tracing==
