Childhood asthma rates have fallen as doctors prescribe infants fewer unnecessary antibiotics, Canadian researchers have found.

Antimicrobial resistance or AMR is a slower-moving pandemic than COVID-19, but one that is worsening every day, says Lori Burrows of McMaster University.

Giving patients antibiotics is standard care before many operations and medical procedures, experts say. So what happens if they no longer work as well?

An outbreak of drug-resistant typhoid in Pakistan has infected around 11,000 people since 2016.

Nearly twice as many people are dying from drug-resistant infections as previously thought, U.S. officials said in a new report.

The report's authors found that drug-resistant bacteria kills nearly as many Canadians as Alzheimer's disease.

Researchers studied 14 commonly used antibiotics in rivers in 72 countries and detected antibiotics at 65 per cent of the monitored sites.

Urgent action is needed to address this growing threat to humankind, the report's authors say.

In some countries, farm animals consume more antibiotics than people, which contributes to antibiotic resistance.

One expert estimates that drug-resistant infections might be killing 120,000 Indian babies a year.
