First of all, an almost universal coverage around 99.99% of NHI itself is the most powerful thing. Because it ensures that if somebody develop symptoms, they can just put on a medical mask, go to a local clinic, get checked and apply for RT-PCR testing. But in other countries if there is no universal coverage, there will be people who think this will increase financial burden on me or things like that. And they would not go to the clinic, which increase the possibility of other people getting infected.
