Signs/Symptoms may include:
Fever
Chills
Headache
Confusion
Cough
Rapid Breathing
Body/Muscle Aches
Rash
Nausea
VomitingAfter 5–6 days, a macular skin eruption develops: first on the upper trunk and spreading to the rest of the body (rarely to the face, palms, or soles of the feet, however).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 that recurs in someone after a long period of latency (similar to the relationship between chickenpox and shingles). This recurrence often arises in times of relative immunosuppression, which is often in the context of a person suffering malnutrition or other illnesses. In combination with poor sanitation and hygiene in times of social chaos and upheaval, which enable a greater density of lice, this reactivation is why typhus generates epidemics in such conditions. Complications
Complications are as follows
Myocarditis
Endocarditis
Mycotic aneurysm
Pneumonia
Pancreatitis
Kidney or bladder infections
Acute renal failure
Meningitis
Encephalitis
Myelitis
Septic shock

Transmission
Feeding on a human who carries the bacterium infects the louse. R. prowazekii grows in the louses gut and is excreted in its feces. The louse transmits the disease by biting an uninfected human, who scratches the louse bite (which itches) and rubs the feces into the wound. The incubation period is one to two weeks. R. prowazekii can remain viable and virulent in the dried louse feces for many days. Typhus will eventually kill the louse, though the disease will remain viable for many weeks in the dead louse.Epidemic typhus has historically occurred during times of war and deprivation.
Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed into the environment to infect other organisms. Species of the other subclass, Cestodaria, are mainly fish infecting parasites. All cestodes are parasitic; many have complex life histories, including a stage in a definitive (main) host in which the adults grow and reproduce, often for years, and one or two intermediate stages in which the larvae develop in other hosts. Typically the adults live in the digestive tracts of vertebrates, while the larvae often live in the bodies of other animals, either vertebrates or invertebrates. For example, Diphyllobothrium has at least two intermediate hosts, a crustacean and then one or more freshwater fish; its definitive host is a mammal. Some cestodes are host-specific, while others are parasites of a wide variety of hosts. Some six thousand species have been described; probably all vertebrates can host at least one species. The adult tapeworm has a scolex (head), a short neck, and a strobila (segmented body) formed of proglottids. Tapeworms anchor themselves to the inside of the intestine of their host using their scolex, which typically has hooks, suckers, or both. They have no mouth, but absorb nutrients directly from the hosts gut.
