A landmark study presented today at ESCMID Global 2025 has revealed that over 3 million children worldwide lost their lives in 2022 due to antimicrobial resistance (AMR)-related infections.

VIENNA,April 12,2025 -- The study underscores the urgent need for both regional and global strategies to controlpaediatric AMR,particularly in high-burden areas such as South-East Asia and Africa. AMR poses a critical threat to children,who are highly vulnerable to infections. Access to new antibiotic formulations is often much more limited for children because of product development delays.

The study data found that in 2022 alone,more than 752,000 children in Southeast Asia and 659,000 children in Africa died of AMR-associated complications. Many of these deaths were linked to the use of Watch antibiotics (drugs with a high risk of resistance) and Reserve antibiotics(last-resort treatments for severe,multidrug-resistant infections).

Watch and Reserve antibiotics are not intended for first-line treatment and their use should be limited only for those who need them to preserve their effectiveness and reduce the development of resistance.

Between 2019 and 2021,the use of Watch antibiotics increased by 160% in Southeast Asia and 126% in Africa. During the same period,the use of Reserve antibiotics rose by 45% in Southeast Asia and 125% in Africa.

Globally,of the more than 3 million children's deaths,2 million were associated with the use of Watch and Reserve antibiotics.

"While the rise in use of Watch and Reserve antibiotics may be necessary in response to the concurrent rise in drug-resistant infections,the sharp rise in use of these drugs presents several serious long-term risks",commented Professor Joseph Harwell,study co-author. "Their increased use,especially without careful oversight,elevates the risk of resistance and limits future treatment options. If bacteria develop resistance to these antibiotics,there will be few,if any,alternatives for treating multidrug-resistance infections."

Several factors contribute to the severity of AMR in low- and middle-income countries,including overcrowded hospitals,poor sanitation,and weak infection prevention measures that facilitate the spread of resistant pathogens within healthcare settings and communities.

Professor Harwell furthered,"Mortality rates,which are already alarmingly high,will continue to rise significantly,particularly in low- and middle-income countries where access to alternative treatments and advanced medical interventions may be limited. Addressing this issue requires urgent and coordinated action at both the regional and global levels."
