### Viral Replication Model
Viruses can replicate through several different mechanisms, primarily categorized into two main processes: **Lytic Cycle** and **Lysogenic Cycle**.
1. **Lytic Cycle**
- **Attachment**: Virus attaches to a host cell.
- **Entry**: Virus injects its genetic material into the host.
- **Replication**: Host cell replicates viral components using its machinery.
- **Assembly**: New viruses are assembled within the host.
- **Lysis**: Host cell bursts, releasing new viruses to infect other cells.
2. **Lysogenic Cycle**
- **Attachment**: Virus attaches to a host cell.
- **Entry**: Virus injects its genetic material (often as DNA) into the host.
- **Integration**: Viral DNA integrates into the host DNA and remains dormant (provirus).
- **Replication**: Host cell replicates, including the viral DNA, during cell division.
- **Induction**: Under certain conditions, the virus can exit, enter the lytic cycle, and produce new viruses.
### Viral Disease Research: Influenza (Flu)
Influenza, commonly known as the flu, primarily affects the **respiratory system** but can also have effects on the **immune system** and, in severe cases, even impact the **circulatory system**. Symptoms of influenza include high fever, cough, sore throat, body aches, fatigue, and headaches. These symptoms arise because the virus attacks the epithelial cells lining the respiratory tract, leading to inflammation and a compromised immune response. The resulting symptoms are a combination of the body's efforts to fight the infection and the direct effects of the virus on the host cells. Supporting evidence from medical literature indicates that the flu virus can cause severe complications, particularly in individuals with weakened immune systems or pre-existing health conditions, further illustrating its impact on the body's systems.
