MRSA and the Workplace

By CDC

Staphylococcus aureus, often referred to simply as "staph," is a type of bacteria commonly carried on the skin or in the nose of healthy people. Sometimes, staph can cause an infection. Staph bacteria are one of the most common causes of skin infections in the United States. Most of these skin infections are minor (such as pustules and boils) and can be treated without antibiotics. However, staph bacteria also can cause serious infections (such as surgical wound infections, bloodstream infections, and pneumonia).

Methicillin-resistant Staphylococcus aureus (MRSA) refers to types of staph that are resistant to a type of antibiotic methicillin. MRSA is often resistant to other antibiotics, as well. While 25% to 30% of the population is colonized with staph (meaning that bacteria are present, but not causing an infection with staph), approximately 1% is colonized with MRSA.

Staph infections, including MRSA, occur most frequently among persons in hospitals and healthcare facilities (such as nursing homes and dialysis centers) who have weakened immune systems. These healthcare-associated staph infections include surgical wound infections, urinary tract infections, bloodstream infections, and pneumonia.

Staph and MRSA can also cause illness in persons outside of hospitals and healthcare facilities. MRSA infections that are acquired by persons who have not been recently (within the past year) hospitalized or had a medical procedure (such as dialysis, surgery, catheters) are known as community-associated MRSA infections. Staph or MRSA infections in the community are usually manifested as skin infections, such as pimples and boils, and occur in otherwise healthy people.

FAQs For the Workplace

NOTE: This information is provided for general workplaces, not healthcare facilities. Healthcare workers should refer to information found at the following link: http://www.cdc.gov/ncidod/dhqp/ar_mrsa.html

Can I get MRSA from someone at work?

MRSA is transmitted most frequently by direct skin-to-skin contact or contact with shared items or surfaces that have come into contact with someone else's infection (e.g., towels, used bandages).

MRSA skin infections can occur anywhere. However, some settings have factors that make it easier for MRSA to be transmitted. These factors, referred to as the 5 C's, are as follows: Crowding, frequent skin-to-skin Contact, Compromised skin (i.e., cuts or abrasions), Contaminated items and surfaces, and lack of Cleanliness. Locations where the 5 C's are common include schools, dormitories, military barracks, households, correctional facilities, and daycare centers.

If I have MRSA, can I go to work?

Unless directed by a healthcare provider, workers with MRSA infections should not be routinely excluded from going to work.

• Exclusion from work should be reserved for those with wound drainage ("pus") that cannot be covered and contained with a clean, dry bandage and for those who cannot maintain good hygiene practices.
• Workers with active infections should be excluded from activities where skin-to-skin contact is likely to occur until their infections are healed.
  

What should I do if I think I have a staph or MRSA infection?

See your healthcare provider and follow your healthcare provider's advice about returning to work.

If I have staph, or a MRSA skin infection, what can I do to prevent the spread of MRSA at work and at home?

You can prevent spreading staph or MRSA skin infections to others by following these steps:

• Cover your wound. Keep wounds that are draining or have pus covered with clean, dry bandages. Follow your healthcare provider's instructions on proper care of the wound. Pus from infected wounds can contain staph and MRSA, so keeping the infection covered will help prevent the spread to others. Bandages or tape can be discarded with the regular trash.
• Clean your hands. You, your family, and others in close contact should wash their hands frequently with soap and warm water or use an alcohol-based hand sanitizer, especially after changing the bandage or touching the infected wound.
• Do not share personal items. Avoid sharing personal items such as uniforms, personal protective equipment, clothing, towels, washcloths or razors that may have had contact with the infected wound or bandage.
• Talk to your doctor. Tell any healthcare providers who treat you that you have or had a staph or MRSA skin infection.
  

What should I do if my uniform, clothing, personal protective equipment or workstation becomes contaminated with MRSA?

• Wash uniforms, clothing, sheets and towels that become soiled with water and laundry detergent. Drying clothes in a hot dryer, rather than air-drying, also helps kill bacteria in clothes.
• Clean contaminated equipment and surfaces with detergent-based cleaners or Environmental Protection Agency (EPA)-registered disinfectants effective at removing MRSA from the environment. It is important to read the instruction labels on all cleaners to make sure they are used safely and appropriately. Environmental cleaners and disinfectants should not be used to treat infections. The EPA provides a list of EPA-registered products effective against MRSA: http://epa.gov/oppad001/chemregindex.htm.
  

What can my boss (employers) do to prevent the spread of staph or MRSA at the workplace?

• Place importance on worker safety and health protection in the workplace
• Ensure the availability of adequate facilities and supplies that encourage workers to practice good hygiene
• Ensure that routine housekeeping in the workplace is followed
• Ensure that contaminated equipment and surfaces are cleaned with detergent-based cleaners or Environmental Protection Agency (EPA)-registered disinfectants
  

Other FAQs About MRSA

Transmission and Risk:

Who gets staph or MRSA infections?

Approximately 25% to 30% of the population is colonized (when bacteria are present, but not causing an infection) in the nose with staph bacteria. Staph infections, including MRSA, occur most frequently among persons in hospitals and healthcare facilities (such as nursing homes and dialysis centers) who have weakened immune systems. These healthcare-associated staph infections include surgical wound infections, urinary tract infections, bloodstream infections, and pneumonia.

How common are staph and MRSA infections?

Staph bacteria are one of the most common causes of skin infection in the United States and are a common cause of pneumonia, surgical wound infections, and bloodstream infections. The majority of MRSA infections occur among patients in hospitals or other healthcare settings; however, it is becoming more common in the community setting. Data from a prospective study in 2003, suggests that 12% of clinical MRSA infections are community-associated, but this varies by geographic region and population.

Signs and Symptoms:

What does a staph or MRSA infection look like?

Staph bacteria, including MRSA, can cause skin infections that may look like a pimple or boil and can be red, swollen, painful, or have pus or other drainage. More serious infections may cause pneumonia, bloodstream infections, or surgical wound infections.

Prevention:

How can I prevent staph or MRSA skin infections?

Practice good hygiene:

• Keep your hands clean by washing thoroughly with soap and water or using an alcohol-based hand sanitizer.
• 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 uniforms and personal protective equipment.
  

Treatment:

Are staph and MRSA infections treatable?

Yes. Many staph skin infections may be treated by draining the abscess or boil and may not require antibiotics. Drainage of skin boils or abscesses should only be done by a healthcare provider.

However, some staph and MRSA infections are treated with antibiotics. If you are given an antibiotic, take all of the doses, even if the infection is getting better, unless your doctor tells you to stop taking it. Do not share antibiotics with other people or save unfinished antibiotics to use at another time.

If after visiting your healthcare provider the infection is not getting better after a few days, contact them again. If other people you know or live with get the same infection tell them to go to their healthcare provider.
