Question 9 How are viral infections different from bacterial infections? 1 pts Bacterial infections can be spread from one person to another, whereas viral infections cannot be spread directly. Bacterial infections can be cured by treatment with some anti-infective drugs, whereas viral infections are not cured by anti-infective therapy. Viruses only cause disease in a person who is immunocompromised, whereas bacteria can cause disease even among immunocompetent people. Viruses are the less mature form of a bacterium, so there is essentially no difference between viral infections and bacterial infections.
