Information:  - Typhoid fever, also known simply as typhoid, is a bacterial infection due to "Salmonella" Typhi that causes symptoms which may vary from mild to severe and usually begin six to thirty days after exposure. Often there is a gradual onset of a high fever over several days. Weakness, abdominal pain, constipation, and headaches also commonly occur. Diarrhea is uncommon and vomiting is not usually severe. Some people develop a skin rash with rose colored spots. In severe cases there may be confusion. Without treatment symptoms may last weeks or months. Other people may carry the bacterium without being affected; however, they are still able to spread the disease to others. Typhoid fever is a type of enteric fever along with paratyphoid fever. The cause is the bacterium "Salmonella" Typhi, also known as "Salmonella enterica" serotype Typhi, growing in the intestines and blood. Typhoid is spread by eating or drinking food or water contaminated with the feces of an infected person. Risk factors include poor sanitation and poor hygiene. Those who travel to the developing world are also at risk and only humans can be infected. Diagnosis is by either culturing the bacteria or detecting the bacterium's DNA in the blood, stool, or bone marrow. Culturing the bacterium can be difficult. Bone marrow testing is the most accurate. Symptoms are similar to that of many other infectious diseases. Typhus is a different disease. A typhoid vaccine can prevent about 30% to 70% of cases during the first two years. The vaccine may have some effect for up to seven years. It is recommended for those at high risk or people traveling to areas where the disease is common. Other efforts to prevent the disease include providing clean drinking water, better sanitation, and better handwashing. Until it has been confirmed that an individual's infection is cleared, the individual should not prepare food for others. Treatment of disease is with antibiotics such as azithromycin, fluoroquinolones or third generation cephalosporins. Resistance to...  - Typhus is any of several similar diseases caused by "Rickettsia" bacteria. The name comes from the Greek "typhus" () meaning smoky or hazy, describing the state of mind of those affected with typhus. The causative organism "Rickettsia" is an obligate intracellular parasitic bacterium that cannot survive for long outside living cells. It is transmitted to humans via external parasites such as lice, fleas, and ticks. While "typhoid" means "typhus-like", typhus and typhoid fever are distinct diseases caused by different genera of bacteria.  - Murine typhus ( also called endemic typhus ) is a form of typhus transmitted by fleas ( Xenopsylla cheopis ) , usually on rats . ( This is in contrast to epidemic typhus , which is usually transmitted by lice . ) Murine typhus is an under - recognized entity , as it is often confused with viral illnesses . Most people who are infected do not realize that they have been bitten by fleas .  - An epidemic (from Greek  "epi" "upon or above" and  "demos" "people") is the rapid spread of infectious disease to a large number of people in a given population within a short period of time, usually two weeks or less. For example, in meningococcal infections, an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered an epidemic.  - Epidemic typhus (also called "camp fever", "jail fever", "hospital fever", "ship fever", "famine fever", "putrid fever", "petechial fever", "Epidemic louse-borne typhus," and "louse-borne typhus") is a form of typhus so named because the disease often causes epidemics following wars and natural disasters. The causative organism is "Rickettsia prowazekii", transmitted by the human body louse ("Pediculus humanus humanus").
