Keep Getting MRSA? Check the Family Pet

sick dogTurns out we can give MRSA, the nasty, drug-resistant infection, to our pets. Then they can carry it around and give it back to us, or transmit it to others.

An overview published in the new issue of Lancet Infectious Diseases cites a few pretty compelling case studies of this phenomenon:

An outbreak on a rehabilitation geriatric unit was traced to a “ward cat” believed to be spreading the bug from person to person. The outbreak passed after the cat was removed from the ward and infection-control measures were put in place.

A separate outbreak in an intensive-care unit was traced to a nurse and his spouse, who was also a nurse. Months later, the nurse and his spouse were linked to a second outbreak. Later, someone figured out the couple’s dog was also infected with MRSA. “Simultaneous decolonisation of the entire household (both nurses and the dog) was ultimately successful,” the authors write.

These findings aren’t new — the Lancet paper is an overview, not a fresh study. But, as MRSA continues to become more prevalent in the community, it’s worth keeping in mind that pets may be playing a role in some cases. Symptoms of MRSA infections in pets can vary, the paper says, and can include a simple rash or the development of pustules.
