Insights into acute and chronic wound infections

Wound infections pose significant challenges to healing and can lead to prolonged clinical conditions with substantial health and economic impacts if not diagnosed and managed promptly. Accurate diagnosis often requires more than just observing clinical signs and symptoms like warmth, pain, swelling, and redness, as these can also be caused by non-infectious factors. A multifactorial approach is essential for precise diagnosis and effective treatment.

Microbial phenotypes, such as planktonic and biofilm forms, play crucial roles in wound infection virulence and the host's inflammatory response. The complexity of wound infections necessitates a comprehensive understanding of these microbial tactics to develop effective clinical strategies for combating infections and promoting better antimicrobial stewardship. This review synthesizes current literature to explore the microbiological, immunological, and clinical distinctions between acute and chronic wound infections. Acute infections are characterized by rapid onset and are often effectively managed with systemic antibiotics. In contrast, chronic wound infections, frequently associated with biofilm formation, present prolonged healing challenges and contribute to antibiotic resistance due to inappropriate and excessive use of antibiotics.

Effective wound management must differentiate between acute and chronic infections to ensure appropriate treatment strategies. For chronic wounds, strategies that focus on biofilm disruption and targeted antimicrobial use are crucial. Recognizing the type of infection and implementing timely therapy can significantly improve wound healing outcomes and reduce the misuse of antibiotics.
