Typhoid fever is caused by the Salmonella organism. It usually presents with high grade fever! It may present with nonspecific symptoms and may mimic alot of disease such as influenza or flu, dengue fever! However, you get typhoid fever from eating or drinking contaminated food. Once you have it , you might have it again for the 2nd time if you dont improve your eating habits. Blood culture usually is needed for the diagnosis and should be done on the first week of the illness. Urine culture on the 2nd week and stool culture on the 3rd week. Culture is done to identify the real organism causing the disease and to know what antibiotics is the patient sensitive, meaning to what medication will his organism respond to. The treatment usually is 10-14 days. If the patient is treated only for 7 days the disease might reccur. Typhidot is another test that can be done. However, it is the Blood Culture which is diagnostic or more reliable.

Causes-

Typhoid Fever is contracted by the ingestion of the bacteria in contaminated food or water. Patients with acute illness can contaminate the surrounding water supply through the stool, which contains a high concentration of the bacteria. Contamination of the water supply can, in turn, taint the food supply. Also, about 3-5% of patients become carriers of the bacteria after the acute illness. Some patients suffer a very mild illness that goes unrecognized. These patients can become long-term carriers of the bacteria. The bacteria multiplies in the gallbladder, bile ducts, or liver and passes into the bowel. The bacteria can survive for weeks in water or dried sewage. These chronic carriers may have no symptoms and can be the source of new outbreaks of typhoid fever for many years.

symptoms-

After infection, symptoms include:

-a high fever from 39 掳C to 40 掳C (103 掳F to 104 掳F) that rises slowly
-chills
-bradycardia (slow heart rate)
-weakness
-diarrhea
-headaches
-myalgia (muscle pain), not to be confused with the more severe muscle pain in Dengue fever, known as "Breakbone fever."
-lack of appetite
-constipation
-stomach pains
-in some cases, a rash of flat, rose-colored spots called "rose spots"
-in some cases, loss of hair resulting from the prolonged high fever
-extreme symptoms such as intestinal perforation or hemorrhage, delusions and confusion are also possible..

Typhoid fever is a condition caused by Salmonella typhi , a gram negative bacteria. This maybe acquired by eating and drinking food and water contaminated with this bacteria. Symptoms are fever, stomach cramps, muscle pain & weakness. This could be diagnosed through laboratory tests done on a blood specimen (Widal test, etc). Confirmatory tests may also be performed and the results related to the clinical symptoms for correct diagnosis.

Look I am not a doctor like u but i am comp engineer. So u can refer the sites which r given by some fellows

Typhoid is caused by the virus typhus. This is a water borne disease. Typhus infects the spleen and the livers. Any medication should be taken under the expert medical care.
This is not contagious in the sense it is not transmitted from person to person contact.

The symptoms are:

- High fever with the varying temperatures either in the morning or in the evening.
- Nausea and hyperacidity
- Rejection of intake of food
- Disturbed motions.

Someothers have suggested some websites which you may check.

Typhoid Fever is an acute illness associated with fever caused by the Salmonellae Typhi bacteria. The bacteria is deposited in water or food by a human carrier, and is then spread to other people in the area.
Typhoid Fever is contracted by the ingestion of the bacteria in contaminated food or water. Patients with acute illness can contaminate the surrounding water supply through the stool, which contains a high concentration of the bacteria. Contamination of the water supply can, in turn, taint the food supply. Also, about 3-5% of patients become carriers of the bacteria after the acute illness. Some patients suffer a very mild illness that goes unrecognized. These patients can become long- term carriers of the bacteria. The bacteria multiplies in the gallbladder, bile ducts, or liver and passes into the bowel. The bacteria can survive for weeks in water or dried sewage. These chronic carriers may have no symptoms and can be the source of new outbreaks of typhoid fever for many years.
After the ingestion of contaminated food or water, the Salmonella bacteria invades the small intestine and enters the blood stream temporarily. It is carried by white blood cells in the liver, spleen, and bone marrow. The bacteria then multiplies in the cells of these organs and reenters the blood stream. Patients develop symptoms, including fever, when the organism reenters the blood stream. Bacteria invade the gallbladder, biliary system, and the lymphatic tissue of the bowel. Here, they multiply in high numbers. The bacteria passes into the intestinal tract and can be identified for diagnosis in cultures from the stool tested in the laboratory.
The patient experiences:

poor appetite,
headaches,
generalized aches and pains,
fever, and
lethargy.
Persons with typhoid fever usually have a sustained fever as high as 103 to 104 degrees Fahrenheit (39 to 40 degrees Centigrade).
