A Tablighi Jamaat religious conference that took place at the "Masjid Jamek Sri Petaling" in Kuala Lumpur's Sri Petaling district between 27 February to 1 March 2020 became a COVID-19 super-spreader event with more than 3,300 cases being linked to the event. By 19 May 2020, the Malaysian Director-General of Health Noor Hisham Abdullah confirmed that 48% of the country's COVID-19 cases (3,347) had been linked to the Kuala Lumpur Tablighi Jamaat cluster. Additionally, nearly 10% of attendees were overseas visitors, causing COVID-19 to spread to other countries in Southeast Asia. On 8 July 2020, this cluster was declared over by the Ministry of Health. Although much more widespread, the Tabligh event was not the first wave of coronavirus in Malaysia. Event Between 27 February and 1 March 2020, the Tablighi Jamaat movement organised an international conference at the "Masjid Jamek Sri Petaling" in Sri Petaling, Kuala Lumpur in Malaysia. The religious gathering was attended by approximately 16,000 attendees (only 12,500 attendees as claimed by the Sri Petaling tabligh group leaders) including about 1,500 from outside Malaysia. Attendees were found to share food, sit close together, and hold hands at the event. According to guests, the leaders of the event did not talk about COVID-19 precautions, but most attendees washed their hands during the event. Malaysian authorities were criticised for allowing the event to go forward. Spread The Sri Petaling Tablighi Jamaat gathering has been linked to more than 620 COVID-19 cases in March 2020, making it the largest-known centre of transmission of the virus in Southeast Asia at that time. At least seven countries have traced their cases back to the Malaysia event; most of the 73 COVID-19 cases in Brunei have been linked to the event, as well as 22 in Cambodia, 13 in Indonesia, 10 in Thailand, 5 in Singapore, 2 in the Philippines, and 2 in Vietnam. By 13 March, the Malaysian Ministry of Health had revised the number of Malaysian Tablighi Jamaat participants from 5,000 to 14,500, raising concerns that more positive cases could be discovered. Of the 14,500 participants, 41 tested positive for COVID-19, which brought the total number of cases in Malaysia to 238. By 17 March, the Sri Petaling event had resulted in the biggest increase in COVID-19 cases in Malaysia, with almost two-thirds of the 673 confirmed cases in Malaysia linked to this event.
