pestilential

What do you fear? Why do you shun me thus. […] I am not Pestilential, nor Leaprous.

A long sicknesse will weary friends at last; but a pestilentiall sicknes auerts them from the beginning.

pestilential fever; pestilential sweating

Now this pestilentiall Summer being well spent, upon the approach of the Winter, and decrease of the Sicknesse, the King […] drawes nearer to the City of London,

Are to their own unhappy Coasts confin’d,

[…]

So Presby’try and Pestilential Zeal

Can only flourish in a Common-weal.

There’s the pestilential nuisances who write for autographs […] They’d none of ’em be missed!
