Can a virus have a really long incubation time, say months, be highly infectious during incubation and have extremely high mortality rate?

As in a virus that gives little to no symptoms for months or even years and suddenly becomes highly lethal?

Would we, with modern medicine, even be able to detect such a virus before it is way to late?

HIV is such a virus. After initial infection People can be asymptomatic for years. - 10-15 years in fact. During this “latency period” Tests would still reveal HIV+ status, but many who are infected do not get tested and continue to spread the virus. Which is why they encourage people who are risk of HIV to get tested regularly … to prevent asymptomatic spread.
