In your opinion how long do you think this epidemic will last?

forever :)

I think the 1+ year estimates are worst case scenarios. Considering how much came out from research these last few months, I believe we can optimistically hope for this whole thing to end in Q4-2020 up to Q1-2021:

1) We have more than one vaccine candidates being trialed in humans already, based on different principles (so maybe if one doesn't work, another or a combination of multiple ones will).
2) We know the virus doesn't mutate fast (especially the surface proteins, and esp. compared to viruses like the flu), so hopefully a vaccine should cover all the existing mutations.
3) We know SARS-CoV guaranteed 1-3 years of immunity, and being these viruses very similar, it could be the case also for this one. This should rule out reinfections (all cases of re-infection reported to date seem to be false PCR negatives, so a minority of people were mistakenly considered [i]recovered[/i])
4) We have treatments that seem to relieve both pre-symptomatic cases (and reduce their chances of getting severe) and others that seem somehow effective also in severe cases. One of them gave positive results in a phase-3 clinical trial just yesterday, iirc. None of them are miracle cures but much much better than what we had two months ago, and it's not that research is going to stop or slow down anytime soon.

Too long.

It feels like that sometimes, but nah. I’m thinking fall next year we’ll be able to breathe a lot easier than we’re able to now.

As long as the media needs it to bash Trump.

Another 2 or 3 months, maybe.

In countries with good controls.. 2 years..

In countries that just let it rip.. 4 months..

We’re all’gun dyyeeeeee

A total of 6 months.

It will return in waves for a few years.

6-18 months. A vaccine will put it under control.

another year or 2 , kinda sucks

It's already been too long..

1 million years

Too long

Until miss nancy runs out of ice cream

Few more months

It's barely even started
