The majority of global COVID-19 deaths have been in countries where many people are obese, with coronavirus fatality rates 10 times higher in nations where at least 50% of adults are overweight, a global study found on Thursday.

The report, which described a "dramatic" correlation between countries' COVID-19 death and obesity rates, found that 90% or 2.2 million of the 2.5 million deaths from the pandemic disease so far were in countries with high levels of obesity.
