1. **Statement I**: "Some of these infections like hepatitis -B and HIV can also be transmitted by sharing injection needles, surgical instruments, etc."
- **Analysis**: Hepatitis B and HIV are indeed viral infections that can be transmitted through blood and bodily fluids. Sharing needles and surgical instruments can lead to the transmission of these viruses, especially in drug use or unsafe medical practices.

2. **Statement II**: "The adolescence period is the period between 18 - 25 years of age."
