IIRC you’d either already have been exposed to the more deadly diseases but have immunity because of widespread exposure, inherited immunity, and being exposed to less dangerous forms that evolved- or in many cases having likely been immunized as a child. As for bacterial infections yea- but people of that time would be at just as much risk. But, they’d be at a lot more risk of viruses from you because they wouldn’t have those immunity factors.
