No. If there was no open wound on your hand and you did not rub it with a shoe.

This is what follows from the question: A man stepped into a pool of blood, and then carefully washed away all the evidence. It seems to me that the question has hidden implications.

Hepatitis B is a persistent thing. If HIV dies in a small drop of blood outside the human body in a couple of minutes, and a larger drop in a couple of hours, then hepatitis B outside the body in a lyophilized form can remain virulent for years (25 years, if I don't confuse). However, for infection, it is necessary that the vir got into the blood, moreover, it got there in sufficient quantity for infection (see the minimum infectious dose), so unless you decide to wipe the sole of the shoe on an open wound, there is nothing to be afraid of - what kind of infection are we we don’t carry everything on our soles, if you think about it.

Simple washing is not effective against hepatitis B, as an example, the site of the bacteriological laboratory at the SES Moscow recommends boiling bed and underwear of patients in a 2% soap and soda solution for 15 minutes, which is to say about objects that have come into direct contact with blood. So it is advisable to treat shoes and the floor on which you walked in it with a disinfectant to which the hepatitis B virus is not resistant, for example, a strong solution of hydrogen peroxide.

But for infection, the virus must get on damaged skin, or mucous membranes. So with appropriate treatment, even if the blood has been contaminated, the risk is not high.

The risk is very low, measured in tenths to hundredths of a percent. If you don't have cuts on your hands, then you can definitely be calm. And if you are very anxious, you can take НBsAg if you have not done this before.
