Statement B: Typhoid fever could be confirmed by widal test.
Statement C: Typhoid causes Intestinal perforation.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Statements B and C are correct.
The correct statements about typhoid fever are Statement B and Statement C.
Typhoid fever is caused by the bacterium Salmonella typhi, not Streptococcus pneumoniae (which causes pneumonia and meningitis). Hence, Statement A is incorrect. The Widal test is a common diagnostic test used to confirm typhoid by detecting antibodies (O and H antigens) in the patient’s blood — making Statement B correct. Typhoid primarily affects the intestines, leading to inflammation, ulcers, and in severe cases, intestinal perforation and internal bleeding, hence Statement C is also correct.
Globally, typhoid remains a major public health issue, especially in regions with poor sanitation. Vaccination, clean drinking water, and proper hygiene are key preventive measures against this potentially fatal disease.
