Staphylococcus aureus, or staph, is a bacterium found in the nose or on the skin of about 20–30% of people in the United States. Staph bacteria are usually harmless but can sometimes cause serious infections. Most staph infections can be treated with antibiotics; however, some strains have developed antibiotic resistance.

Methicillin-resistant Staphylococcus aureus (MRSA) is the name for the strains of staph bacteria that have become resistant to certain antibiotics that are usually used to treat staph infections. MRSA is the most common drug-resistant infection found in hospital settings, and it is on the rise.

The two main types of MRSA include healthcare-associated MRSA (HA MRSA), which is found mainly in hospital patients and long-term care facility residents, and community-associated MRSA (CA MRSA), which is found in those who have not had contact with healthcare facilities.

1. MRSA is resistant to certain _____ used to treat staph infections.

a. temperatures
b. antibiotics
c. vitamin supplements
d. nutrients

How MRSA is Spread

MRSA is usually spread by direct contact with an infected wound or from contaminated hands, usually those of healthcare providers. Also, people who carry MRSA but do not have signs of infection can spread the bacteria to others (i.e., people who are colonized).

Employees should be encouraged to practice good personal and hand hygiene, such as:

problems
In healthcare facilities, MRSA can cause severe problems.
  • Keep hands clean by washing thoroughly with soap and water or by using an alcohol-based sanitizer when soap and water is not immediately accessible.
  • Keep cuts and scrapes clean and covered with a bandage until healed.
  • Avoid contact with other people's wounds or bandages.
  • Avoid sharing personal items, such as towels, washcloths, razors, or clothes.
  • Wash soiled sheets, towels and clothes in hot water with bleach and dry in a hot dryer.

In healthcare facilities, such as a hospital or nursing home, MRSA can cause severe problems including:

  • bloodstream infections
  • pneumonia
  • surgical site infections
  • sepsis
  • death

2. MRSA is usually spread by _____.

a. animals
b. food and drink
c. air conditioning systems
d. direct contact with an infected wound

symptoms
Most MRSA infections appear as a bump or infected area on the skin.

Symptoms

The symptoms of MRSA infections depend on the part of the body that is infected. MRSA is often confused with a spider bite. Most MRSA infections appear as a bump or infected area on the skin that may be:

  • red
  • swollen
  • painful
  • warm to the touch
  • full of pus or other drainage

Preventing MRSA in a Healthcare Setting

Every year, lives are lost because of the spread of infections in hospitals. Infection control is key to stopping MRSA in hospitals. Proper hand washing is the most effective way to prevent the spread of infections in hospitals. If you are a patient, don't be afraid to remind friends, family, and health care providers to wash their hands before getting close to you.

prevention
There are several steps to take to help prevent MRSA in a healthcare setting.

Other steps health care workers can take include:

  • covering coughs and sneezes
  • staying up to date with immunizations
  • using gloves, masks and protective clothing
  • making tissues and hand cleaners available
  • following hospital guidelines when dealing with blood or contaminated items

Whenever possible, patients with MRSA will have a single room or will share a room only with someone else who also has MRSA. Healthcare providers will put on gloves and wear a gown over their clothing while taking care of patients with MRSA. Visitors and health care workers caring for people in isolation may be required to wear protective garments and must follow strict hand hygiene procedures. Contaminated surfaces and laundry items should be properly disinfected.

4. What is the key to stopping MRSA in hospitals?

a. Training
b. Education
c. Infection control
d. Rules

Depending on the specific workplace situation, some personal protective equipment (PPE) may be needed as a barrier against the transmission of MRSA from an infected person to a non-infected employee. This may include, but is not limited to, the use of gloves, eye protection and facemasks (e.g., surgical masks).

Sanitation

This OSHA standard (1910.141) requires an employer to provide:

  • hot and cold running water or tepid running water in each lavatory
  • hand soap or similar cleansing agents
  • individual hand towels or sections thereof, of cloth or paper, warm air blowers or clean individual sections of continuous cloth toweling, convenient to the lavatories
  • individual clean towels to employees who use showers

5. Some personal protective equipment (PPE) can act as a _____ against the transmission of MRSA.
