From what I understand, based on other coronaviruses it's far more likely than not that there's some sort of immunity for at least a few months.

Coronavirus has been detected on particles of air pollution by scientists investigating whether this could enable it to be carried over longer distances and increase the number of people infected.
The work is preliminary and it is not yet known if the virus remains viable on pollution particles and in sufficient quantity to cause disease.
The Italian scientists used standard techniques to collect outdoor air pollution samples at one urban and one industrial site in Bergamo province
