MRSA is an abbreviation for Methicillin-Resistant Staphylococcus Aureus, which refers to a type of bacteria that has developed resistance to multiple antibiotics, including methicillin and other commonly used drugs. It is a strain of the bacterium Staphylococcus aureus, commonly known as staph, that has become highly resistant to various antibiotics due to genetic mutations.
Staphylococcus aureus is commonly found on the skin or in the nose of healthy individuals, and it usually does not cause harm. However, under certain circumstances, such as when the skin is compromised or the immune system is weakened, staph bacteria can enter the body and cause infections.
MRSA infections can occur in both community or healthcare settings, with healthcare-associated MRSA (HA-MRSA) being commonly acquired in hospitals or other healthcare facilities. Community-associated MRSA (CA-MRSA) is usually acquired outside healthcare settings, such as schools, gyms, or households.
Infections caused by MRSA range from minor skin infections, such as boils or abscesses, to more serious and potentially life-threatening conditions, such as pneumonia, bloodstream infections, or surgical site infections. Treating MRSA infections can be challenging, as these bacteria have developed resistance to many antibiotics, limiting the treatment options available.
Preventive measures to reduce the spread of MRSA include practicing good hygiene, such as frequent handwashing, keeping wounds clean and covered, avoiding contact with others' wounds or personal items, and maintaining a clean environment.
