Brill–Zinsser disease
Specialty	Infectious diseases

Brill–Zinsser disease is a delayed relapse of epidemic typhus, caused by Rickettsia prowazekii. After a patient contracts epidemic typhus from the fecal matter of an infected louse (Pediculus humanus), the rickettsia can remain latent and reactivate months or years later, with symptoms similar to or even identical to the original attack of typhus, including a maculopapular rash.^[1] At such times, typhus can be transmitted to other individuals through fecal matter of the louse vector, and generate a new epidemic of the disease.^{[citation needed]}
