Researchers in British Columbia, Canada, have found MRSA infected bedbugs. MRSA is an anti-biotic resistant staff infection which this blog has covered before here and here. The researchers found that in impoverished communities (like homeless populations living in close quarters in shelters and residential hotels for) harbor conditions for bedbugs to carry MRSA. They found several dangerous strains of the infection in bedbug samples they collected.
There is, according to the scientists in this article on the story, no imminent danger of this development being a vector for widespread transmission of MRSA. However, it is always important to keep an eye on diseases with such potential to spread, unchecked through the global population.
