Once rare, the superbug methicillin-resistant Staphylococcus aureus (MRSA) infects hundreds of thousands of people in the U.S. each year and kills about 20,000. New research led by Washington University School of Medicine in St. Louis sheds light on how MRSA is introduced into households and, once there, how it can spread among family members, including the furry ones. Understanding MRSA’s transmission dynamics is critical to devising effective preventive tactics.
The highly contagious norovirus causes diarrhea and vomiting and is notorious for spreading rapidly through densely populated spaces, such as cruise ships, nursing homes, schools and day care centers. There are no treatments for this intestinal virus. A new study led by scientists at Washington University School of Medicine in St. Louis has shown that gut microbes can tamp down or boost the severity of norovirus infection based on where along the intestine the virus takes hold.
