The WHO is OK risking the lives of people in Taiwan in order to keep the mainland happy. You would think that the WHO would put the health of people, regardless of where they live, ahead of politics.
If the virus' impact in Puerto Rico was very different than it was in the rest of the United States, the WHO would note it publicly. But Taiwan't situation was actively suppressed by the WHO because of Beijing.
Anyway, the WHO/Taiwan debacle seems to resulted in Taiwan handling this pandemic better than anyone else, considering their proximity to China and the huge amount of trade and travel between them. Taiwan just ignored the WHO and did their own thing, which was the best thing.
