To clarify the pandemic status in Western Pacific countries or territories.

The WHO’s daily situation reports of COVID-19 were reviewed from January 20, 2020, to March 24, 2020. Changes in the infections, deaths, and the case fatality rate (CFR) in Western Pacific countries or territories were counted.

As of March 24, a total of 17 countries or territories had reported the presence of COVID-19 in the Western Pacific Region, 96,580 people have been infected and a total of 3502 deaths. Fifty-three percent (9/17) of these countries or territories had their first case within 2 wk since the WHO’s first report, most are China’s neighbors with a large and dense population. No other country or territory in this region reported a new infection from January 30 to February 28. However, 8 (47.0%) countries or territories have reported the first cases in 3 wk since February 28, almost all are islands. Many countries maintained a small number of infections for a long time after the first report, but a rapid increase occurred later. Deaths occurred in 8 countries with a total CFR of 3.63%, and the CFR varies widely, from 0.39% (Singapore) to 7.14% (Philippines).

The regional spread of COVID-19 urgently requires an aggressive preparedness for the Western Pacific Islands.
