Question

Why would it be easier for a doctor to tell that someone has a viral infection when the virus is in the

lytic cycle?

Answer 1

Diagnosis of Bacterial and Viral Infections

But your doctor may be able to determine the cause by listening to your medical history and doing a physical exam. If necessary, they also can order a blood or urine test to help confirm a diagnosis, or a "culture test" of tissue to identify bacteria or viruses.
