Staph infection rates

More than 119,000 people suffered from bloodstream Staphylococcus aureus (staph) infections in the United States in 2017 – and nearly 20,000 died, according to a new Vital Signs report by the Centers for Disease Control and Prevention (CDC).

The findings show that hospital infection control efforts successfully reduced rates of serious staph infections in the U.S. Recent data, however, show that this success is slowing and staph still threatens patients.

The new data reflect rates for all Staphylococcus aureus infections: methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible Staphylococcus aureus (MSSA). While MRSA is often better known, the report underscores that all staph can be deadly and that healthcare providers and administrators can take prevention steps to protect their patients.

According to electronic health record data from more than 400 acute care hospitals and population-based surveillance data from CDC’s Emerging Infections Program, MRSA bloodstream infections in healthcare settings decreased nationally by approximately 17 percent each year between 2005 and 2012. These reductions have recently started to stall, causing concern. The report also showed an almost 4 percent increase in MSSA infections that started outside of a healthcare setting each year from 2012 to 2017.

The rise in staph infections in the community may be linked to the opioid crisis. As reported by CDC last year, 9 percent of all serious staph infections in 2016 happened in people who inject drugs — up from 4 percent in 2011. Patients presenting with recurring staph infections should prompt healthcare providers to consider whether injection drug use could be the cause. To decrease staph infections in people who inject drugs, healthcare providers should link patients to drug-addiction treatment services and provide information on safe injection practices, wound care, and how to recognize early signs of infection.  

Staph is a type of germ often found on human skin and on surfaces and objects that touch the skin. While the germ does not always harm people, it can get into the bloodstream and cause serious infections, which can lead to sepsis or death.

The risk for serious staph infection is greatest when people stay in healthcare facilities or have surgery, when medical devices are placed in their body, when they inject drugs, or when they come into close contact with someone who has staph. To reduce the spread of staph in the community, everyone should keep their hands clean, cover wounds, and avoid sharing items that contact skin, like towels, razors, and needles to prevent the spread of staph.

Healthcare providers and administrators can protect people by making staph prevention a priority. This includes implementing CDC recommendations, including the use of contact precautions (gloves and gowns), continually reviewing their facility infection data available from CDC’s National Healthcare Safety Network, and considering other interventions if they are not meeting infection reduction goals.

Based on the facility, additional prevention measures could include screening patients at high risk, or decolonization (special bathing or medication that reduces germs people may carry and spread) at high risk periods or for certain types of procedures. Several healthcare systems in the United States have reported success after tailoring their approach to staph.
