The CDC has issued a warning about the spread of Bartonella quintana, a bacterial infection transmitted by body lice, which poses a significant risk to homeless populations and organ transplant recipients. The infection, known as trench fever, can lead to severe health issues, including potentially fatal heart valve infections. The disease is challenging to diagnose and treat, particularly in vulnerable communities, and is exacerbated by rising homelessness. The CDC recommends that transplant facilities inquire about donors' housing status to mitigate risks.

Recent research published in PLOS Biology suggests that body lice, not just rat-transmitted fleas, played a significant role in spreading the bubonic plague during the 14th century. The study found that body lice can effectively transmit the plague-causing bacterium Yersinia pestis, with infected lice remaining contagious for up to a week and capable of infecting humans through their bites. This new evidence highlights the potential for body lice to be more effective vectors of the plague than previously understood.
