A recent study published in The Lancet has shed light on the growing health crisis in India caused by antimicrobial resistance (AMR), linking 33% of sepsis-related deaths in the country to antibiotic resistance. Sepsis, a severe and often deadly condition, occurs when the body’s immune system reacts aggressively to an infection, leading to widespread inflammation, organ failure, and potentially death. Without timely treatment, sepsis can be fatal, and the excessive and improper use of antibiotics has significantly worsened the situation in India.
According to the study, bacterial infections were responsible for 60% of the 2.99 million sepsis-related deaths in India in 2019, with 1.04 million deaths associated with AMR. Of these, 290,000 deaths were directly attributed to antibiotic-resistant infections. The findings highlight the serious threat posed by AMR, which has become one of the most pressing global health challenges.
The escalating global AMR crisis
The problem of antibiotic resistance is not confined to India alone. The Lancet report, drawing from research by the Global Research on Antimicrobial Resistance (GRAM) Project, presents a grim global outlook. The study indicates that over 39 million people worldwide could die from antibiotic-resistant infections in the next 25 years if immediate action is not taken. This comprehensive analysis of AMR trends provides insights into how deaths from antibiotic resistance have shifted over time and predicts future trends.
Dr. Mohsen Naghavi, leader of the AMR Research Team at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, emphasized the urgency of the crisis. “Understanding how trends in AMR deaths have changed over time, and how they are likely to shift in the future, is vital to make informed decisions to help save lives,” Dr. Naghavi stated.
Key findings in India
The study’s data, gathered from 22 pathogens and 84 pathogen-drug pairings across 11 infection types, has painted a clear picture of the most problematic bacteria in India. Among the most prevalent antibiotic-resistant pathogens are:
- Escherichia coli (E. coli): Responsible for a range of infections, including gut infections, E. coli has become increasingly resistant to antibiotics.
- Klebsiella pneumoniae: Known for causing pneumonia and urinary tract infections, this bacterium is notorious for being difficult to treat in hospitals.
- Acinetobacter baumannii: Primarily found in healthcare settings, it is a major cause of infections acquired in hospitals and is highly drug-resistant.
These three pathogens account for a significant portion of antibiotic-resistant infections in India, which are contributing to the high sepsis mortality rates.
The impact on vulnerable populations
The situation is particularly dire among children and other vulnerable groups. The study found that of the 500,000 sepsis-related deaths in children under the age of five in 2019, bacterial infections were responsible for 325,000. In this age group, Streptococcus pneumoniae emerged as the deadliest pathogen, causing more child fatalities than any other bacteria.

In addition to pediatric deaths, the report highlights that lower respiratory and thoracic infections were the leading cause of sepsis-related deaths across all age groups in India, accounting for approximately 27% of the total. These infections, when combined with antibiotic resistance, make treatment options even more limited and increase the risk of fatal outcomes.
Rising global resistance
Globally, the study revealed alarming trends in antibiotic resistance. Methicillin-resistant Staphylococcus aureus (MRSA), a highly resistant bacterium, saw its death toll more than double from 57,200 in 1990 to 130,000 in 2021. Meanwhile, gram-negative bacteria, which are particularly hard to treat, showed increasing resistance to powerful antibiotics like carbapenems. The number of deaths caused by carbapenem-resistant infections increased from 127,000 in 1990 to 216,000 in 2021.
Urgent need for action
The findings of this study underscore the urgent need for better antibiotic stewardship, improved infection control measures, and increased investment in the development of new antibiotics. In India, where antibiotic misuse is widespread, public awareness campaigns, stricter regulations on antibiotic sales, and better diagnostic facilities are essential to combat the growing AMR crisis.
Without immediate intervention, antibiotic resistance could undermine decades of progress in medical treatment, making once-treatable infections deadly. The rise in sepsis deaths linked to AMR in India serves as a stark warning of the global threat that unchecked antibiotic resistance poses. Governments, healthcare providers, and international organizations must prioritize coordinated efforts to address this looming public health catastrophe.
