Question 2

Can typhoid fever be deadly if untreated?

Accepted Answer

Yes, typhoid fever can be life-threatening if not treated promptly. Severe cases can lead to complications like intestinal perforation, internal bleeding, and organ failure. Early diagnosis and antibiotic treatment significantly reduce the risk of death.

Question 3

How is typhoid fever transmitted from person to person?

Question 4

What are the early symptoms of typhoid fever?

Accepted Answer

Early symptoms include a high, prolonged fever, fatigue, weakness, headache, stomach pain, and loss of appetite. Some individuals may also experience a rash of flat, rose-colored spots and digestive issues like constipation or diarrhea.

Question 5

How is typhoid fever diagnosed through blood tests?

Accepted Answer

Typhoid fever is diagnosed using blood cultures, the Widal test, or other antibody-based tests. Blood cultures are the most reliable for detecting Salmonella Typhi, especially in the early stages of infection.

Question 6

Can typhoid fever come back after treatment?

Accepted Answer

Yes, relapse can occur if antibiotics aren't completed, or if reinfection happens—especially in cases involving drug-resistant strains.

Question 7

Which organ does typhoid fever primarily affect?

Accepted Answer

Typhoid fever mainly affects the gastrointestinal tract, especially the intestines. It can also impact the liver, spleen, and in severe cases, the bloodstream and other organs if the infection spreads.

Question 8

When is the typhoid vaccine recommended?

Accepted Answer

The typhoid vaccine is recommended for individuals traveling to regions where typhoid fever is common, such as parts of Asia, Africa, and Latin America. It may also be advised for laboratory workers handling Salmonella Typhi or during outbreak situations.

Question 9

Why does typhoid fever cause bradycardia (slow heart rate)?

Accepted Answer

Bradycardia during typhoid fever is part of the “Faget sign,” where a high fever is accompanied by a slow pulse. This response is uncommon in most infections and is considered a clinical clue in diagnosing typhoid and a few other illnesses.

Question 10

Can typhoid fever be treated effectively with antibiotics?

Accepted Answer

Yes, antibiotics are the standard treatment for typhoid fever. They help eliminate the bacteria from the body, reduce symptoms, and prevent complications. Early treatment shortens the duration of illness and lowers the risk of transmission.
