Covid19 vs selfdefense

It you are approached by an individual who is not wearing a mask, you have no idea if they are covid19 positive and for whatever reason they start to spit on you during a altercation.
Can this be considered a form of a biological attack?
Assault with a deadly biological weapon?
Attempted murder if you get covid19 from them?
What should our response be if we can not get away for the hostile individual/s?
