Bacterial infections second leading cause of death worldwide
E. coli is one of 30 bacteria studied in the Global Burden of Disease research program.
Bacterial infections are the second leading cause of death worldwide, after heart disease, shows a very large study published on Tuesday, citing staphylococcus aureus and pneumococcus among the most deadly bacteria.
< p class="e-p">This study, published in The Lancet, selected around 30 bacteria – the most commonly implicated in infections – and assessed how many deaths were associated with them.
These measurements are carried out within the framework of the Global Burden of Disease. This vast research program, funded by the Bill Gates Foundation, is of an unparalleled scale, involving several thousand researchers in most countries of the world.
En Ultimately, deaths associated with these bacteria are the second leading cause of death worldwide after coronary heart disease, which includes heart attacks, conclude the authors.
With 7.7 million deaths linked to bacterial infection, one in eight deaths can be attributed to them, although these figures date back to 2019, before the COVID-19 pandemic.
Of the thirty or so bacteria selected, five alone account for more than half of the deaths: Staphylococcus aureus, E. coli, pneumococcus, Klebsiella pneumoniae< /em> and pyocyanin bacillus.
Staphylococcus aureus is the leading bacterial cause of death in 135 countries, the study says.
In the youngest – under five years old – however, pneumococcal infections are the most deadly.
For the researchers, these results illustrate how infections bacteria are an urgent public health priority.
They call for work on the prevention of infections, better use of antibiotics – to avoid in particular the phenomenon s resistance – and more effective use of vaccination.
