There's only a "1point" plan required to get Thailand back on track......get rid of Prayut Chan-O-Chan and his inadequate cabinet! These guys are light weights on the political stage, and now the Biden administration is favoring Singapore and Vietnam over Thailand in the Indo-Pacific alliance...speaks volumes on the success of Prayuts governance!
The important measure when it comes to lifting Red list status is the so called “Positivity Rate”. This is the measure of positive tests compared to the number of tests. This addresses the issue of simply reducing the number of cases by testing less. Even if you only test 100 people, if 30 of them are positive, it is still 30%. Typically, 5% is seen as a level at which it is safe to move a country to a green travel lists. There are other factors such as vaccination rate, but positivity is key. Currently, Thailand has a staggering 30% compared to 3.2% of the U.K. until this figure reduces to below 10% it’s unlikely Thailand will be moved off red lists. It’s has fallen from a high of 38% on August 17 but a long way to go. See attached link and graph.
