Now the thinktank has updated its data and methodology and re-issued a report on the safest countries and regions, Forbes reported.
The ranking was not just about how many infections there are at present, or how many deaths Covid-19 has caused in each country.
Whether a country has been hit hard by Covid-19 or not is taken into consideration, but also factored into the rankings was whether there is political will and social acceptance of quarantine and lockdown measures.
It also considered whether the national and local governments cooperate well, a nation has good monitoring and detection, and a strong medical system.
Another part of the equation related to how vulnerable a country was to economic dislocation because of the pandemic, plus how well-equipped a country was to handle emergencies.
The United States ranked a distant 55th, behind Hungary, Vietnam, Malaysia, and Bulgaria.
The most dangerous nations for Covid according to the ranking were Somaliland, South Sudan, Afghanistan and Mali.
According to Forbes, Deep Knowledge Group said it looked at more than 140 parameters and considered more than 35,000 data points, both up significantly from June's report.
"Deep Knowledge Group's new Covid-19 special analytical case study is designed to classify, analyse and rank the economic, social and health stability achieved by each of the 250 countries and regions included in its analysis, as well as the strengths, weaknesses, opportunities, and threats or risks that they present in the battle against the global health and economic crisis triggered by Covid-19," Deep Knowledge Group said.
