Antibiotics are medicines wont to prevent and treat bacterial infections. Antibiotic resistance occurs when bacteria change in response to the utilization of those medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and therefore the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance results in higher medical costs, prolonged hospital stays, and increased mortality. The world urgently must change the way it prescribes and uses antibiotics. albeit new medicines are developed, without behaviour change, antibiotic resistance will remain a serious threat. Behaviour changes must also include actions to scale back the spread of infections through vaccination, hand washing, practising safer sex, and good food hygiene.
