What is the epidemiology of MRSA?

What is the epidemiology of MRSA?

Results: In 2017, an estimated 119,247 S. aureus bloodstream infections with 19,832 associated deaths occurred. During 2005–2012 rates of hospital-onset MRSA bloodstream infection decreased by 17.1% annually, but the decline slowed during 2013–2016.

How common is MRSA pneumonia?

The estimated incidence of community-acquired MRSA (CA-MRSA) pneumonia is 0.51 to 0.64 cases per 100,000.

Does Staphylococcus aureus cause community-acquired pneumonia?

Staphylococcus aureus is an infrequent cause of community-acquired pneumonia (CAP), accounting for ≈3% of cases in which a bacterial cause is identified, but it is a recognized cause of influenza-associated CAP (1–4). Methicillin-resistant S.

Is MRSA community-acquired pneumonia?

MRSA can cause community-acquired pneumonia, and needs to be considered in the at-risk group of patients.

What is methicillin susceptible Staph aureus?

MSSA, or methicillin-susceptible Staphylococcus aureus, is an infection caused by a type of bacteria commonly found on the skin. You might have heard it called a staph infection. Treatment for staph infections generally requires antibiotics.

What is methicillin-resistant Staphylococcus aureus pneumonia?

Methicillin-resistant Staphylococcus aureus (MRSA) has become one of the leading etiologies of nosocomial pneumonia as a result of an increase in staphylococcal infections caused by methicillin-resistant strains paired with extended ventilatory support of critically, and often, chronically ill patients.

How is staph aureus pneumonia treated?

The only therapies available to treat S. aureus pneumonia are antibiotics, a modality that is jeopardized by the organism’s remarkable ability to acquire antimicrobial resistance.

Is methicillin susceptible Staphylococcus aureus contagious?

MRSA is very contagious and can be spread through direct contact with a person who has the infection. It can also be contracted by coming into contact with an object or surface that’s been touched by a person with MRSA. Though a MRSA infection can be serious, it may be treated effectively with certain antibiotics.

What is the prevalence of Staphylococcus aureus infection in the US?

A large surveillance program of nosocomial bloodstream infections in the United States showed that among all S. aureus isolates, the percentage of MRSA isolates increased from 22% in 1995 to 57% in 2001 [ 12 ].

What is the incidence of infective endocarditis in Staphylococcus aureus bacteremia?

Infective endocarditis is among the most severe complications of S. aureus bacteremia, and its incidence has been increasing [ 2 ].

Why is Staphylococcus aureus still so dangerous?

This quote from Sir Alexander Ogston in 1882 describes several facets of Staphylococcus aureus that continue to plague physicians in modern times. This centuries-old pathogen still causes significant morbidity and mortality despite huge advances in medical care.
