Researchers warn that a changing climate could increase the risk of deadly diseases carried by rodents, as shifts in temperature and rainfall alter rodent populations and push them into closer contact with people. The warning highlights how climate-driven changes to ecosystems may expand outbreaks of illnesses such as hantavirus and leptospirosis, and experts are calling for closer monitoring of rodent populations and disease patterns.

An NPR report examines how cities like Washington, DC and New York are tackling rat infestations by changing human behavior rather than only targeting the rodents. The approach focuses on better waste management and food disposal habits, arguing that rats thrive when people leave trash accessible. Officials in both cities have run public campaigns urging residents to secure garbage and deny rats food sources.

Health officials are investigating a flea-borne typhus outbreak in the Wilshire Center neighborhood of Los Angeles. The bacterial illness, spread to humans by fleas that have fed on infected rodents, cats or opossums, can cause fever, headache and rash. Local news coverage has raised concerns about rodent populations and sanitation conditions in the area, and residents are being advised to take precautions against fleas and keep pets treated.
