Scientists warn that shifting climate conditions could change the risks posed by deadly rodent-borne diseases. As temperatures and rainfall patterns alter habitats, rodent populations may move into new areas, potentially increasing human exposure to pathogens such as hantavirus and leptospirosis. Researchers say understanding these ecological shifts is becoming increasingly important for public health planning.

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.

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.
