The art of infection prevention
Preventing infection is an important facet of nearly all programs designed to promote effective use of antibiotics, an area known as antimicrobial stewardship. According to the World Health Organization (WHO), global efforts to preserve the effectiveness of antibiotics must include strategies for preventing any infection that might be treated with the drugs, whether justifiably or not. Teena Chopra, an infectious-disease specialist at the Wayne State University School of Medicine, is fully behind this approach. Because infections are difficult to diagnose and treat quickly, Chopra says that the biggest impact will come from preventing infections in the community, not just in hospitals. Chopra is keen to keep this hygiene momentum going, and points out that the pandemic has revealed considerable weak spots. “This COVID-19 pandemic exposed a lot of vulnerabilities in our core health infrastructure,” she says. “We dealt with a lack of infection control in alternative health-care settings, like nursing homes, schools, daycare centers, dialysis centers, nursing facilities and rehab facilities.” She thinks that those who run these services need to have a more prominent role in antimicrobial stewardship. Without such measures, people will continue to transfer microbes to each other. The risk of transmission can be limited by using microbe-destroying surfaces such as copper, and through rigorous disinfection with chemicals and exposure to ultraviolet light. However, such measures can be difficult to implement in communities. The only two universally effective methods are hand hygiene and staying away from others, Chopra says. “Hand hygiene is the cornerstone — not only in the hospital, but everywhere.” These strategies might seem simple, but they require people to change their behavior, and that is easier said than done.
