Even New York City rats can get COVID, study finds
A new study has found that New York City rats can actually be infected with the COVID-19 virus. "Our findings highlight the need for further monitoring of SARS-CoV-2 in rat populations for potential secondary zoonotic transmission to humans," said the lead author of the study Dr. Henry Wan.
CNN reports researchers trapped and processed samples from rats around the city and found that 16.5 percent of the tested rats tested positive for the virus. The report writes that the virus was "identified in sewage water systems" and "coincides with outbreaks in resident human populations," but "no evidence has shown that SARS-CoV-2 viruses in sewage water are infectious." This shows "that sewage rats may have been exposed to the virus through airborne transmission ... or indirect transmission from unknown fomites."

Dr. J. Scott Weese, director of the Centre for Public Health and Zoonoses at the University of Guelph remarked that the findings are a "reminder for the future, and that we need to be approaching things in the broader context, animal and human health all together."
