No.Well if you don't get symptoms immediately upon the onset of a disease, but you have the disease and you can pass it on to someone else - then by that very possibility - you have to accept asymptomatic transmission.
In this context, person to person infection requires a substantial transfer of a virus from the infected person to the non infected person. A modest transfer will be dealt with by any functional immune system and there is no 'infection' or symptoms.
For the infected person to be able to pass on sufficient quantity of the virus, they will need to have high levels themselves so will be sick, probably home in bed. Most infections occur in hospitals, care homes or at home where people are caring for a family member or friend who is genuinely ill.
