I agree with Marcello, mutations happen all the time, so it more or less a question of time when the next new infectious disease comes. However, multiple factors need to happen all at once for a new virus/bacteria to appear and be able to successfully infect humans, so it is generally a very rare thing. And if anything this year taught humanity so much in terms of how to deal with the pandemic. We can reduce the risk of new infectious diseases emerging and handle them better if they do.
