COVID-19 4-6 months is very extreme and it won't be that long. They've rolled out one vaccine already, with others coming quickly. Officially, we're at around 17M having caught the virus but the general thought is at best, we've only caught half the cases with the more likely estimate being only 1 in 3 or 1 in 4 due to tests not being available early, people not getting tested, people not having symptoms severe enough to get tested or being asymptomatic. So realistically, at least 10% of the US has caught it, and we're probably looking at 15-20%. We're still at 200K per day officially, which is 1.4M per week. That's 0.5% of the population per week. Double that, and we're probably at 1% of the population getting it each week. So by the end of January, we'll be at 20-25% having caught it. And that's before people getting vaccinated.
The next major hurdle is Christmas. We didn't see as much of a Thanksgiving bump as expected. It was more of a continuation of the trend of cases skyrocketing. All of the trackers show the daily case 7 day average having leveled off. The last day or two has actually seen a slight downturn (we'll see if that's just a blip or a trend). Hopefully Christmas follows Thanksgiving in not having a noticeable bump, though we won't know until mid-January.
As more people get infected and people start getting the vaccine, there will be fewer and fewer people to catch and spread the virus. If I could bet on it, I'd bet on restaurants being open way sooner than 6 months. If you made that 4 months, I'd still bet the under and wouldn't think twice.
