Coronavirus: how Taiwan was able to overcome the worldwide infection without any restrictive measures
This research was able to show us that case management measures such as communication tracing and isolation can reduce transmission rates from 2.5 to 1.53 (quarantine was the most important link in reducing this number).
The case-based policy did not greatly avert transmission of the contagion, but it did manage to decrease the transmission of secondary cases to third parties, subject to quarantine. But on the other hand, measures to protect the people with the help of distancing and wearing masks turned out to be quite effective and decreased the number of R from 2.5 to 1.3.
Researchers believe that it was the connected action of both policies to combat the coronavirus that helped Taiwan successfully contain its spread.
The combined work of both approaches resulted in an R number using the two methods, 0.82 units and, lower, 0.62. The authors also realized that for a successful containment, a high-quality policy to protect the population is needed, even if the already existing cases of infection and further spread were small. It turned out that none of the politicians could have comprised the infection on their own, even in a country with a good healthcare system.
