Dasch, in Principles and Practice of Pediatric Infectious Diseases (Fifth Edition), 2018. Brill-Zinsser disease, the relapsing form of epidemic typhus, typically occurs in a susceptible host years or decades after the primary infection; however, the mechanisms of reactivation and the cellular reservoir during latency are poorly understood.

Epidemic typhus acquired from flying squirrels has also been milder and shorter in many cases, although severe illnesses have been reported. Typhus fever (Brill's disease) has been reported only sporadically from areas other than the coastal region of the northeastern United States. Body lice are vectors of three bacteria which cause human disease: Rickettsia prowazekii , the agent of epidemic typhus; Bartonella quintana , the agent of trench fever; and Borrelia recurrentis , the agent of relapsing fever. It occurs when the bacteria become active again in a person who was previously infected. Patients usually present with a fever and may have a rash (usually maculopapular) or an eschar (the bite site of the ectoparasite). Brill-Zinsser diseases is considered milder than classical epidemic typhus, although it remains potentially life-threatening.
Some people who previously had epidemic typhus will develop a milder form of the disease years later called Brill-Zinsser disease. In 1967, Atlacomulco, a county in the state of Mexico that had been free of typhus for 5 years, experienced an outbreak of louseborne typhus associated with a case of Brill-Zinsser disease in a 76-year-old man who had a history of epidemic typhus.

Nowadays, with antibiotics to treat the original typhus, it is estimated that between 10 and 20 percent of typhus patients have recurrences (Olson 70), but what the rates were in Austen’s time is unknown.
Most recently, the Jane Austen Society of North America suggested that she may have died from Brill-Zinsser disease. Brill-Zinsser disease (recrudescent infection) Rickettsiae may remain latent in the lymphoid tissue for years. Hans Zinsser1878-1940 American microbiologist, epidemiologist, and immunologist whose main research concerned epidemic louse-borne typhus and other rickettsial diseases. Sporadic cases of Brill-Zinsser disease can occur in the US, primarily among immigrants from areas endemic for epidemic typhus, but they pose little risk for spread except from individuals infested with body lice. Intriguingly fascinating and entertaining reading for anyone who is interested in how society copes with catastrophe and pain.
Patients with Brill-Zinsser disease acquired epidemic typhus earlier or lived in an endemic area. Sylvatic typhus is a rare and milder form of epidemic typhus occurring the eastern United States.

From 1910 to 1945, there were many studies on epidemic typhus and murine typhus in Korea.
the disease, the Rickettsiae may remain latent in the lymphoid tissue or organs for years.Such latent infection may at times be reactivated leading to recrudescent typhus (Brill Zinsser disease). Epidemic typhus is an infectious disease caused by the bacterium Rickettsia prowazekii and transmitted by body lice (Pediculus humanus corporis).

View PDF Prognosis If the patient has recovered naturally, without the use of antibiotics, there is the risk of relapse/recurrence in some rickettsial infections: for example, epidemic typhus (leading to Brill-Zinsser disease) or scrub typhus, which can occur many years after the initial infection. Zinsser corrects or updates this notion, saying (page 173 in the Bantam Classic edition) : "There are two distinct types of true typhus virus . A recrudescence of body lice is being observed as the numbers of individuals living under social conditions which predispose individuals to infestation have increased.
Skin lesions are similar to those of epidemic typhus but are more mild.

Two patients suffering from Brill-Zinsser disease were treated with azithromycin, which did not prove effective. Brill–Zinsser disease (recrudescent typhus) resembles acute epidemic typhus, but tends to be milder, with a lower risk of death and a shorter course. Zinsser: Varieties of typhus virus and the epidemiology of the American form of European typhus fever (Brill’s disease). Brill-Zinsser disease: A form of recurring typhus caused by a bacterium called Rickettsia proazekii and transmitted by lice. Brill–Zinsser disease may, in turn, be the source of new outbreaks when conditions facilitate louse infestation and transmission .

This means that in all cases where the ICD9 code 081.1 was previously used, A75.1 is the appropriate modern ICD10 code. When a persons immune systems is weak, viable organisms retained in the body are activated, causing recurrent typhus. prowazekii bacteremia often occur in Brill-Zinsser patients, an epidemic typhus outbreak may supervene when body louse infestation is prevalent in the considered population. The signs and symptoms are similar to those of epidemic typhus but are less severe, of shorter duration, and rarely fatal.

If Brill’s disease is indeed a recrudescence of typhus in individuals who previously have had the disease, as postulated by Zinsser,1 then it should be occurring at the present time in those parts of the world where typhus epidemics have been widespread in the past 25 to 50 years. The Brill-Zinsser clinical form of typhus is a reactivation of the disease which can occur years after the primary episode. Brill-Zinsser disease should be considered as a possible diagnosis for acute fever in any patient who has lived in an area where epidemic typhus is endemic. This disease remains a major health threat because it could re-emerge at any moment. This reactivation phenomenon is unique to this group of rickettsial diseases and produces as a milder and shorter episode in comparison to the original infection. The best way to prevent typhus infections is to minimize exposure to the ectoparasite vectors (human body lice, fleas, ticks and mites) and rodents which may carry infected fleas. Fleaborne typhus is a milder disease than is louseborne typhus; its attack rate is highest during summer and early fall months.
The titres fall rapidly during convalescence.
Brill-Zinsser disease - an endogenous reinfection associated with the "carrier state" in persons who previously had epidemic typhus fever. Epidemic typhus is usually diagnosed by serology; a fourfold rise in titer is diagnostic. Brill–Zinser 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. Data Sources and Methods A total of 22 typhus epidemics during 1655–1918 were identified from historical records of disease in Mexico. prowazekii, called Brill-Zinsser disease, may occur months or years after the initial illness, during times of extreme stress or when the immune system becomes weakened. Epidemic typhus occurs in two clinical forms: the primary febrile illness and the recrudescence of infection (Brill–Zinsser disease).
Grob, Gerald N., Zinsser, Hans Overview: The classic chronicle of the impact disease and plagues have had on history and society over the past half-millennium. Brill-Zinsser disease is a recurrent form of epidemic typhus, occurring years after an initial attack. prowazekii, produces a similar but much milder illness then during the primary disease','. The 1812–1819 Ottoman plague epidemic was one of the last major epidemics of plague in the Ottoman Empire. For centuries, it has been associated with overcrowding, cold weather, and poor hygiene. However, we could not definitely determine whether the patient suffered from primary or recrudescent (Brill-Zinsser disease) typhus. Brill-Zinsser disease, first described by Nathan Brill in 1913 at Mount Sinai Hospital in New York City, is a mild form of epidemic typhus which recurs in someone after a long period of latency (similar to the relationship between chickenpox and shingles).
