I work in a hospital. What do I actually need to do so I do not carry infections home to the twins?

The pharmacy counter is in the OPD block. In a normal night I hand medicines to people with every cough and fever in Lucknow. During the current viral season it is nonstop. What I do now: I change my clothes in the parking area before coming home, wash my hands before touching the children, and keep my hospital bag outside the flat. My wife thinks I am being paranoid. My mother thinks I am not being careful enough. Health workers with small kids, what is your routine? Is there anything evidence-based that actually matters, and what is just theatre?
