In the context of human health, epidemiology, and disease etiology, which of the following statements regarding human diseases and their causative pathogens are correct?

  1. Japanese Encephalitis is a viral infection affecting the central nervous system, primarily transmitted to humans through the bite of infected Culex mosquitoes.Cevap
  2. B
    Typhoid fever is a acute gastrointestinal infection caused by a protozoan parasite transmitted through fecal-oral contamination.
  3. Hepatitis B is a viral infection targeting hepatocytes in the liver, capable of causing both acute hepatitis and long-term chronic liver damage.Cevap
  4. D
    Tuberculosis is a contagious infectious disease primarily affecting lungs, caused by an opportunistic fungal pathogen.

Cevap

The statements confirming that Japanese Encephalitis is a viral disease transmitted by Culex mosquitoes, and that Hepatitis B is a viral liver infection, are correct.
The statements identifying Japanese Encephalitis as a mosquito-borne viral infection and Hepatitis B as a viral liver disease are scientifically accurate. Both correctly specify the pathogen category and clinical target.

Adım Adım Çözüm

1
Analyze the etiology and transmission mode of Japanese Encephalitis.
Japanese Encephalitis is confirmed to be caused by a virus (JEV) and vectored by Culex mosquitoes.
Accurate pathogen classification (viral) and vector identification (Culex mosquito).
2
Evaluate the causative agent of Typhoid fever.
Typhoid fever is identified as a bacterial infection (Salmonella Typhi), contradicting the claim of a protozoan parasite.
Salmonella Typhi is a bacterium that infects the intestinal tract and bloodstream.
3
Analyze the target organ and pathogen of Hepatitis B.
Hepatitis B is verified as a viral disease affecting hepatocytes in the human liver.
HBV is a double-stranded DNA virus specifically targeting hepatic tissue.
4
Evaluate the pathogen type of Tuberculosis.
Tuberculosis is identified as a bacterial disease (Mycobacterium tuberculosis), contradicting the fungal pathogen claim.
Mycobacterium tuberculosis is a rod-shaped bacterium with a unique waxy cell wall.
