Hello, thank you for asking at HealthReplies.com
Typhoid fever is an infectious disease caused by the bacteria Salmonella Thipii and Salmonella Parathipii. Bacteria are transmitted through food, which is when consuming food contaminated with patient feces. The high risk of experiencing binfeksi will increase in the group of people throwing away eating habits in the open, cooking food not until cooked, not hygienic in processing and serving food and the habit of not washing hands before eating and after going to the bathroom. Patients will experience complaints of fever more than a week. Where the fever is up and down, but when the fever goes down does not reach the normal temperature. Accompanied by complaints of nausea, vomiting and diarrhea. Typical of typhoid fever will be accompanied by a white tongue with a red edge and the tip of the tongue will vibrate when extended, called a typhoid tongue.
To establish the diagnosis of typhoid fever, it is needed evidence of clinical data that doctors get and laboratory support, one of which is a widal test. Widal test can be done in areas that have limited investigations. Ideally, the inspection is carried out twice, namely during the first Sunday and the week after. If there is an increase in titer 4 times it is said to be positive infected. In examinations performed only once, a positive value is obtained if the titer is 1/160 or more, but must be confirmed again with clinical data. Meanwhile, other tests that are more sensitive are tubex and blood, stool and urine cultures.
To get an explanation of the results of your examination, it is better to consult with a doctor who asks for an examination to be done matching with the clinical data they have.
Meanwhile, maintain personal hygiene and food. To break the chain of transmission.
Thus hopefully useful.
