You can get sick by touching an unclean surface because harmful germs, such as bacteria and viruses, can reside on these surfaces. When you touch the surface and then your face, mouth, or eyes, you can transfer these pathogens into your body, leading to infections. Additionally, some germs can survive for extended periods on surfaces, increasing the likelihood of transmission, especially in high-traffic areas. Regular handwashing and sanitizing surfaces can help reduce this risk.
