# COVID-19 pandemic in Southeast Asia

The COVID-19 pandemic in Southeast Asia is part of the ongoing worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was confirmed to have spread to Southeast Asia on 13 January 2020, when a 61-year-old woman from Wuhan tested positive in Thailand, making it the first country other than China to report a case. The first death occurred on 2 February, involving a 44-year-old Chinese man in the Philippines, also the first outside China. By 24 March, all states in the region had announced at least one case.
As of 10 February 2025, Vietnam has the highest number of cases, ahead of Indonesia and Malaysia, while Indonesia has the highest number of deaths. On the other hand, Timor-Leste has the least cases and deaths.

## Background

On 12 January 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan, Hubei, China, which was reported to the WHO on 31 December 2019.
The case fatality ratio for COVID-19 has been much lower than SARS of 2003, but the transmission has been significantly greater, with a significant total death toll.

## Timeline

Southeast Asia was among the first regions to be affected by the pandemic. Thailand, the Philippines, Singapore, Cambodia, Vietnam, and Malaysia reported the index cases in January 2020, while the rest were in March.
Southeast Asia faced its first wave in January 2021 by reporting more than 15,000 cases daily, mostly contributed by Indonesia. The second rise in infections began in early June amidst of the surge of the Delta variant, and peaked from July to August when the region averaged almost 100,000 cases and 3,000 deaths daily. All countries had its cases rising rapidly, leading to lockdowns and activities restrictions.
The third wave hit Southeast Asia in February 2022 as it reported more than 200,000 cases daily due to the spread of the Omicron variant. However, the death number was four to six times lower than the previous peak.
