A resident of South Lake Tahoe, California, has tested positive for plague, marking the first reported human case in El Dorado County since 2020. Health officials believe the individual contracted the disease from an infected flea bite while camping and is currently recovering at home. Plague, caused by the bacterium Yersinia pestis, remains rare but persists in some areas of the United States. Separately, another case of plague was reported in northern New Mexico, where a person may have been exposed while camping in Rio Arriba County near the Colorado border. Additionally, Alabama reported its first measles case of the year involving an unvaccinated child under five years old who likely contracted the virus during international travel.
