**Core Concept**
Infectious healthcare waste refers to waste materials that pose a risk of transmitting diseases to humans or the environment. This includes waste contaminated with blood, bodily fluids, or other potentially infectious materials. Proper disposal of infectious healthcare waste is crucial to prevent the spread of infectious diseases.

**Why the Correct Answer is Right**
The correct answer is around 1-3% of the total healthcare waste generated. This is because most healthcare waste is non-infectious, consisting of items like paper, plastic, and other disposable materials. However, waste that is contaminated with bodily fluids, such as blood or urine, or waste from procedures involving high-risk patients, like those with tuberculosis or HIV, is considered infectious and requires special handling and disposal. The exact percentage may vary depending on the healthcare setting and the specific types of waste generated.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely too high, as it would imply that a significant portion of healthcare waste is infectious, which is not the case.
**Option B:** This option is too low, as it would suggest that only a small fraction of healthcare waste is infectious, which is not accurate.
**Option C:** This option is not specific enough and does not provide a clear percentage, making it an unclear choice.

**Clinical Pearl / High-Yield Fact**
It's essential to note that the World Health Organization (WHO) recommends that healthcare facilities segregate infectious waste and dispose of it through incineration or autoclaving to prevent the spread of diseases.

**Correct Answer:** C. 1-3%
