Via io9: ‘To work out what kind of diseases the rats of NYC were carrying, the scientists trapped 133 rats at five sites around the city, focussing on those inside residential buildings in particular, for obvious disease-spreading reasons.They then used molecular testing to look for known bacterial pathogens and viruses in the rats’ tissue and excretions.
They found that 15 of the 20 bacterial pathogens they were testing for were present in the rats, as well as one virus, Seoul hantavirus, which causes Ebola-like heamorrhagic fever in humans. This is the first time the virus has been documented in New York City, and the genetic clues in the rats suggest it’s a new arrival.
Perhaps even more interestingly and worryingly, the researchers also found 18 completely new viruses in the rats. None of these have been seen in humans as yet, but the scientists say that transmission is possible.’
