Answer: A. Bed bugs (Cimex) have been linked with hepatitis B virus. ---
Hepatitis B virus has been associated with?
- Cimex species
- Xenopsylla species
- Pthirus species
- Tabanids species
- Steam bugs
Answer: A. Cimex species (bed bugs) have been studied for potential mechanical transmission of Hepatitis B. ---
Hepatitis B virus has been associated with
- Cimex species
- Xenopsylla species
- Pthirus species
- Tabanids species
- Glossina species
Answer: A. While not definitively proven, bed bugs (Cimex species) have been investigated as potential mechanical vectors for Hepatitis B virus, though human-to-human transmission remains the primary route. ---
Which of the following specimens contain/s hepatitis B virus in an infected person?
- Blood
- Semen
- Saliva
- All of these
- None of the above
Answer: D. HBV is found in blood, semen, vaginal secretions, saliva, breast milk, and other body fluids. Blood has the highest viral concentration. This explains its transmission routes — sexual contact, needlesharing, vertical (mother to child), and rarely saliva (deep kissing, bites). ---
