Chemistry World– December 23, 2019. The US Center for Disease Dynamics, Economics and Policy has developed a tool called the Drug Resistance Index (DRI), which maps out the efficacy of antibiotics for particular pathogens in a specific location. In a 2019 study, India was found to have the lowest DRI among 41 countries, indicating that the country has high levels of resistance to most commonly consumed antibiotics in the country. Other countries with extremely low DRI scores include Ecuador, Thailand and Venezuela. Wealthy countries such as Sweden, Canada and Denmark were found to be the best stewards of antibiotics.
