# COVID-19 pandemic in Tonga

The COVID-19 pandemic was confirmed to have reached Tonga on 29 October 2021 with a traveller who tested positive in quarantine. Several more cases were found in January and February 2022 in a minor outbreak during the aftermath of the 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami as other countries delivered aid. Tonga had followed a "Covid-free" policy.

## Background

A novel coronavirus that caused a respiratory illness was identified in Wuhan City, Hubei Province, China, in December 2019, and was reported to the World Health Organization (WHO) on 31 December 2019, which confirmed its concern on 12 January 2020. WHO declared the outbreak a Public Health Emergency of International Concern on 30 January, and a pandemic on 11 March.
The case fatality rate of COVID-19 is much lower than that of SARS, a related disease which emerged in 2002, but its transmission has been significantly greater, leading to a much greater total death toll.

## Timeline
