Both, Hepatitis B and AIDS are

Options

A. Cause by Retro-viruses
B. Transmitted through sexual contact
C. Congenital diseases
D. Transmitted through infected blood

Answer

**Step-by-Step Solution:**

1. **Identify the Pathogens:**
- Hepatitis B is caused by the Hepatitis B virus (HBV), which is a DNA virus.
- AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV), which is a retrovirus.

**Hint:** Remember that retroviruses are a specific type of virus that replicate in a host cell through the process of reverse transcription.

2. **Transmission Routes:**
- Hepatitis B is primarily transmitted through contact with infectious body fluids, such as blood, semen, and vaginal secretions. This can occur through sexual contact, sharing needles, or from mother to child during childbirth.
- AIDS is also transmitted through similar routes, including sexual contact, sharing of infected needles, and from mother to child.

**Hint:** Consider the different ways viruses can spread and how they relate to bodily fluids.

3. **Distinguishing Features:**
- While both diseases can be transmitted through sexual contact and infected blood, it is important to note that Hepatitis B is not caused by a retrovirus, whereas AIDS is specifically caused by a retrovirus (HIV).

**Hint:** Focus on the classification of viruses and the specific characteristics that differentiate them.

4. **Conclusion:**
- Both Hepatitis B and AIDS are viral infections that can be transmitted through sexual contact and infected blood, but they are caused by different types of viruses. Hepatitis B is not caused by a retrovirus, while AIDS is.

**Hint:** Summarize the key differences and similarities in terms of causative agents and transmission methods.
