Answer:
normal concentration
Explanation:
You do have to be vigorous with your hand-washing though. That’s why the advice is that hands should be washed thoroughly for at least 20 seconds.
No matter how smooth and soft your skin might feel, when you are nanoparticle-sized – like a virus – it is bumpy, uneven, and full of little ridges.
Viruses stick to the skin and get lodged in those minuscule crinkles, which is why shifting them requires active hand-washing.
Other substances are also effective, such as alcohol-based gels. Those with high alcohol content (usually 60% to 80%) will also dissolve the virus. But the antibacterial properties of such products will have no effect on viruses.
