Lockdowns might temporarily slow down infection, but it just postpones the inevitable and prolongs the misery. Hence the second wave. If lockdowns work long term, it should have been “one and done.” Since you can not keep it tight for prolonged periods, the virus comes back with a vengeance.
This is not how it works. If the lockdown is planned and executed properly, the virus dies (in that region). It will "come back only" only if the lockdown is not enforced.
In a few extreme instances, such as in New Zealand and some other islands the virus was pretty much "locked out". In some other regions the virus still got in, but its spread was very limited. In a few other places, the lockdowns very successful in the first wave, but the virus came back when the restrictions were relaxed.
On a personal level, by practicing my own lockdown and avoiding crowded spaces so far I was able to avoid the virus, but if I started to relax my social distaancing and went to bars and travel in a rush hour on crowded buses, I might have contracted it.
Opposite of a lockdown is Trump's latest idiotic and irresponsible encouragement of travel and group gatherings for this Thanksgiving. While the US Center for Disease Control and Prevention recommends against traveling for Thanksgiving as a means to preventing further spread of the coronavirus, Trump's invitation to spread the virus will cause the infections in USA grow very rapidly and more broadly, quite possibly to 300,000 to 500,000 new cases per day. Watch out the stats next week.
President Donald Trump's annual Thanksgiving proclamation calls for Americans to "gather" for the holiday, even though federal public health officials have explicitly warned against it.
The final line of the proclamation, issued by the White House press secretary's office Wednesday evening, reads: "I encourage all Americans to gather, in homes and places of worship, to offer a prayer of thanks to God for our many blessings."
