What is likely to harbor bacteria?

Surfaces that are frequently touched, such as doorknobs, light switches, and mobile phones, are likely to harbor bacteria due to constant contact with hands. Additionally, areas like kitchen sponges, cutting boards, and bathroom fixtures can also accumulate bacteria from food and bodily fluids. Soft surfaces like towels and bedding can retain moisture, providing an ideal environment for bacterial growth. Regular cleaning and disinfection can help reduce bacterial presence on these surfaces.
