Viruses that persist in the body and cause recurrent disease are called

Question

BlackTom AI · Accepted Answer

When we consider viruses that stay in the body and can cause disease again later, the key concept is persistence in a dormant or hidden state. 
Option 1: 'Resistant' describes a pathogen's ability to withstand antimicrobial agents, not its capacity to remain in a host and reactivate. This misinterprets persistence as drug resistance rather than a latent infection. 
Option 2: 'Cytopathic' refers to virus-induced damage to host cells, which is about immediate effects during infection, not about long-term dormancy or recurrence. 
Option 3: 'Opportunistic' characterizes pathogens that take advantage of weakened host defenses, not the mechanism of long-term persistence that causes relapses. 
Option 4: 'Oncogenic' means capable of causing cancer; while some viruses are oncogenic, that term does not describe recurrent or latent behavior. 
Option 5: 'Latent' correctly names viruses that persist in the body in a dormant form and can reactivate to cause recurrent disease, capturing the notion of long-term persistence and episodic symptoms. 
By evaluating each option against the idea of long-term dormancy and potential relapse, 'Latent' is the precise fit for viruses that persist and recur.
