Rising Concern Over Antibiotic-Resistant Bacteria

Recently, the Centers for Disease Control and Prevention (CDC) in the United States issued a warning about a sharp increase in infections caused by dangerous bacteria that resist some of the strongest antibiotics. This rise in infection rates is particularly concerning when it comes to bacteria known as carbapenem-resistant Enterobacterales (CRE).

What Are Carbapenems and Why Are They Important?

Carbapenems are used to treat severe bacterial infections that resist multiple drug therapies, such as pneumonia, bloodstream infections, bone infections, and urinary tract infections. These drugs are among the most potent antibiotics available, but carbapenem-resistant Enterobacterales (CRE) threaten the effectiveness of these medications.

In 2020 alone, CRE infections resulted in approximately 12,700 cases and 1,100 deaths in the United States. These figures highlight the severity of these bacteria and the challenges they pose to the healthcare system.

Findings of the Recent Report

According to a report by CDC scientists, between 2019 and 2023, the rate of carbapenem-resistant Enterobacterales infections increased by up to 461%. This surge represents a significant jump in the spread of infections that have developed resistance to many available treatments.

The study noted that the majority of these infections occur in hospitals, making them currently rare in the general community. However, their rapid spread in healthcare settings raises concerns about their potential transmission to the wider community.

What Causes the Increase in Infections?

Researchers at the CDC are still investigating the causes of the increased infections, but they suspect several factors are at play. Among these are poor hand hygiene among healthcare providers, inadequate cleaning and disinfection of medical equipment, and insufficient testing to access infection detection tools.

When infections are not quickly identified, effective antibiotic treatment and infection control interventions may be delayed, increasing the chances of transmission from one patient to another.

Spread of Resistant Genes

Bacteria containing the NDM gene are among the most widespread, as they can spread through healthcare facilities using medical equipment like ventilators and intravenous tubes. Daniel Rankin, a co-author of the report, points out that infections associated with this gene can spread to other environments outside hospitals.

The concern lies in the fact that effective antibiotics against NDM-CRE infections are only available via intravenous injection, meaning common infections may require intravenous antibiotic treatment and hospital admission.

Conclusion

Carbapenem-resistant Enterobacterales infections represent a significant health challenge requiring special attention from the medical community. With the continuous increase in these infections, efforts must be intensified to prevent and treat them promptly. It is crucial to improve hygiene in hospitals and provide the necessary tools for early detection of these infections to prevent their widespread transmission.
