Medieval Diseases Have Returned to Los Angeles
21st August 2026
In what can only be described as a stunning failure of state and local policy and leadership, Los Angeles County recorded its highest tally of flea-borne typhus cases in 2025, confirming 220 diagnoses, up from 187 the year before, according to the county’s Department of Public Health. Almost nine in ten of those patients ended up hospitalized. Fleas that feed on infected rats, opossums, and other small mammals carry the bacteria behind the disease to humans, and Los Angeles has watched the case count climb for years. The 2025 total marks the sharpest jump yet.
