How come multiple viruses/pathogens don’t interfere with one another when in the human body?

I know that having multiple diseases can never be good for us, but is there precedent for multiple pathogens “fighting” each other inside our body?

Before antibiotics, syphilis could sometimes be treated by infecting the patient with malaria. The high fever of the malaria infection could kill the syphilis bacteria; it was called pyrotherapy. Problematic because sometimes the malaria accidentally killed the patient... but people would take that bet because the alternative was terminal neurosyphilis.
