Help! If a virus has an incubation period of 12-24 months, then it is most likely --

Answer 1

Not sure if this is what you meant, but this is what I understoodit on what you said. Based on existing literature, the incubation period (the time from exposure to development of symptoms) of SARS-CoV-2 and other coronaviruses (e.g. MERS-CoV, SARS-CoV) ranges from 2–14 days.

Answer 2

my best guess would be LTBI (latent tuberculosis infection)

most incubation periods are in the range of 3 weeks to 3 months, though some cancer viruses have incubation periods of 10 years long. exc..

tuberculosis: 6-24 months

aids: 1-15 years

leukemia: 2–12 years

good luck!
