While many countries around the world are hitting new highs in coronavirus cases, Taiwan has achieved a different kind of record — 200 days without a locally transmitted case.

Taiwan holds the world’s best virus record by far and reached the new landmark on Thursday, even as the pathogen explodes anew in Europe and the U.S. Taiwan’s last local case came on April 12; there has been no second wave.

What did this island with 23 million people do right? It has had 550 confirmed cases, with only seven deaths. Experts say closing borders early and tightly regulating travel have gone a long way toward fighting the virus. Other factors include rigorous contact tracing, technology-enforced quarantine and universal mask wearing. Further, Taiwan’s deadly experience with SARS has scared people into compliance.
