Top 5 Deadly Bacteria That Killed Nearly 6.8 Lakh Indians in 2019

Globally, there were 77 lakh deaths associated with 33 bacterial pathogens (both resistant and susceptible to antimicrobials) across 11 infectious syndromes.

“The 33 bacterial pathogens that we investigated in this study are a substantial source of health loss globally, with considerable variation in their distribution across infectious syndromes and locations,” said the Lancet study.

Need for Strategies to Prevent Bacterial Infections

The researchers stated that, “they should be considered an urgent priority for intervention within the global health community. Strategies to address the burden of bacterial infections include infection prevention, optimized use of antibiotics, improved capacity for microbiological analysis, vaccine development, and improved and more pervasive use of available vaccines,”.

The researchers estimated deaths associated with 33 bacterial genera or species across 11 infectious syndromes in 2019 using methods from the Global Burden of Diseases (GBD), Injuries, and Risk Factors Study 2019, in addition to a subset of the input data described in the Global Burden of Antimicrobial Resistance 2019 study.

This study included 343 million individual records or isolates covering 11,361 study-location-years.

From an estimated 13.7 million infection-related deaths in 2019, there were 7.7 million deaths associated with the 33 bacterial pathogens (both resistant and susceptible to antimicrobials) across the 11 infectious syndromes estimated in this study.

Five leading pathogens

— Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae, Klebsiella pneumoniae, and Pseudomonas aeruginosa — were responsible for 54.9 percent of deaths among the investigated bacteria.

“The age-standardized mortality rate associated with these bacterial pathogens was highest in the sub-Saharan Africa super-region, with 230 deaths per 100a%000 population,” said the study.

S. aureus was the leading bacterial cause of death in 135 countries and was also associated with most deaths in individuals older than 15 years, globally.

Among children younger than 5 years, S pneumonia was the pathogen associated with most deaths.

“In 2019, more than 6 million deaths occurred as a result of three bacterial infectious syndromes, with lower respiratory infections and bloodstream infections each causing more than 2 million deaths and peritoneal and intra-abdominal infections causing more than 1 million deaths,” the study noted.
