Signs and symptomsTyphoid fever is characterized by a slowly progressive fever as high as 40 °C (104 °F), profuse sweating, gastroenteritis, and nonbloody diarrhea. Less commonly, a rash of flat, rose-colored spots may appear.[4]Classically, the course of untreated typhoid fever is divided into four individual stages, each lasting approximately one week. In the first week, there is a slowly rising temperature with relative bradycardia, malaise, headache and cough. A bloody nose (epistaxis) is seen in a quarter of cases and abdominal pain is also possible. There is leukopenia, a decrease in the number of circulating white blood cells, with eosinopenia and relative lymphocytosis, a positive diazo reaction and blood cultures are positive for Salmonella typhi or paratyphi. The classic Widal test is negative in the first week.
In the second week of the infection, the patient lies prostrate with high fever in plateau around 40 °C (104 °F) and bradycardia (sphygmothermic dissociation), classically with a dicrotic pulse wave. Delirium is frequent, frequently calm, but sometimes agitated. This delirium gives to typhoid the nickname of "nervous fever". Rose spots appear on the lower chest and abdomen in around a third of patients. There are rhonchi in lung bases. The abdomen is distended and painful in the right lower quadrant where borborygmi can be heard. Diarrhea can occur in this stage: six to eight stools in a day, green with a characteristic smell, comparable to pea soup. However, constipation is also frequent. The spleen and liver are enlarged (hepatosplenomegaly) and tender, and there is elevation of liver transaminases. The Widal reaction is strongly positive with antiO and antiH antibodies. Blood cultures are sometimes still positive at this stage. (The major symptom of this fever is the fever usually rises in the afternoon up to the first and second week.)
In the third week of typhoid fever, a number of complications can occur:
The fever is still very high and oscillates very little over 24 hours. Dehydration ensues and the patient is delirious (typhoid state). By the end of third week the fever has started reducing (defervescence). This carries on into the fourth and final week.
is marked by high fever, headache, loss of appetite, vomiting, and constipation or diarrhea. The patient typically develops an enlarged spleen. About 30% of patients have rose spots on the front of the chest during the first week of illness.
this is not how you spell fever
Paratyphoid fever has three stages: an early stage marked by high fever; a toxic stage with abdominal pain and intestinal symptoms, and a long period of recovery from fever (defervescence).
a toxic stage with abdominal pain and intestinal symptoms
Patients with intestinal complications have symptoms resembling those of appendicitis: intense cramping pain with soreness in the right lower quadrant of the abdomen.
an early stage marked by high fever
Most patients with paratyphoid fever recover completely, although intestinal complications can result in death. With early treatment, the mortality rate is less than 1%.
Travelers in countries with high rates of paratyphoid fever should be careful to wash hands before eating and to avoid meat, egg, or poultry dishes unless they have been thoroughly cooked.
Salmonella Typhi AH is also known as Paratyphoid fever. This is an illness.
Because the disease is unusual in the United States, the doctor may not consider paratyphoid in the diagnosis unless the patient has the classic symptoms of an enlarged spleen and rose spots.
Acute typhoid is very uncommon. But then it is possible to have acute typhoid, when patient gets the loading dose of the bacteria. Usually the fever is paratyphoid fever in such cases.
Yes. Both of them are bacteriocidal and can be taken together. Both of them are drug of choice for paratyphoid fever and second drug of choice for typhid fever.
It can be transmitted from animals or animal products to humans or from person to person.
Patients with intestinal perforation or hemorrhage may need surgery if the infection cannot be controlled by antibiotics.
