With 1.27 million deaths in 2019, antimicrobial resistance (AMR) has resulted in the deaths of more people than HIV/AIDS and malaria combined. AMR is listed among the top 10 global public health priorities by the WHO. The magnitude of the AMR burden is poorly prioritized in the public health sector, and its impact is difficult to accurately estimate due to a lack of sufficient data, especially in Africa. The misuse and overuse of antibiotics for various non-medical purposes is widely reported, especially in low-income developing countries, as one of the key contributors to AMR, yet little effort is put in place to curb the menace. Also, the clinical pipeline of new antimicrobials is scanty. This review explores the mechanism of AMR, the effects of AMR on health and the public sector with regard to morbidity, mortality, and economic losses, and the impact of COVID-19 on AMR. Recent potential therapies that are used to combat AMR, such as phage therapy, and how they could bring about development in the public health sector were discussed. Also, the impact of vaccines and preventive strategies to curb the spread of AMR in the public sector were highlighted.
