What You Need to Know About MRSA
Overview
MRSA, or methicillin-resistant Staphylococcus aureus, is a highly resistant strain of bacteria. It has two main types: one that spreads in hospitals and healthcare settings, and another found in the community. While the majority of MRSA cases occur in hospitals, only about 14% are community-spread.
Understanding MRSA
Recently, MRSA infections have been in the spotlight. These bacteria, dubbed the "cockroach of bacteria" by experts, are known for their resilience and ability to spread easily, often through unwashed hands. Approximately one in three people carry staph bacteria, and about one million carry the MRSA strain.
Antibiotic Resistance
Over time, bacteria have evolved to resist treatment. Staph bacteria have become largely untreatable with older antibiotics like penicillin, and by the 1960s, they started resisting methicillin as well.
Public Concerns
While MRSA isn't new, public concern has increased. However, Dr. Julie Gerberding from the CDC emphasizes that there’s no need for panic. MRSA spreads primarily through close contact and shared items like towels and razors. Common-sense hygiene, such as washing with soap and water, is crucial in prevention.
MRSA Infections
MRSA typically causes skin infections such as boils and abscesses. However, it can also lead to life-threatening blood infections. There are approximately 94,000 serious MRSA infections annually, with an estimated 18,000 deaths?"slightly more than those caused by AIDS.
Hospital vs. Community Strains
MRSA has two strains: hospital-acquired and community spread. Most cases are hospital-related, but recent high-profile cases in schools have raised concerns. Dr. Gerberding reassures that large-scale cleaning of schools isn’t necessary; routine cleaning with germicides is sufficient.
Concerns for Parents
Parents should note that about 200 children annually experience serious MRSA infections, but most are successfully treated with routine antibiotics. Those in communal living situations, like prisons, are more at risk due to shared toiletries and poor hygiene.
Hospital Protocols
Some hospitals test all incoming patients for MRSA, but this isn’t universally required. Gerberding warns against unnecessary isolation, which can lead to less frequent care and complications like bed sores.
The Deadly Strain: USA300
The community strain, known as USA300, can be particularly severe, causing white blood cells to explode and leading to inflammation. It also produces a toxin called PVL, which scientists are actively studying.
Conclusion
While new antibiotics are being developed, the reality of bacterial evolution means that basic hygiene practices like proper handwashing and wound care remain our best defense against infections like MRSA.
