There is a bit of misinfo going around that the coronavirus will weaken over time.
No one knows for sure if that's true, as UW biologist @CT_Bergstrom has explained https://twitter.com/CT_Bergstrom/status/1281388738895949825

I suspect that this misinterpretation comes from a misread of coronavirus evolution. It's thought that cold-causing coronaviruses began infecting humans roughly 800 years ago.... https://www.cell.com/trends/microbiology/fulltext/S0966-842X(16)30133-0
...and some scientists wonder if those cold-causing coronaviruses were more potent back then and caused ancient pandemics.
But that's just speculation. SARS-CoV-2 is here for a while.

Hmm, let's start by dispelling an oversimplification:
Immunity against viruses involves more than just antibodies. Antibodies are just one part of our body's arsenal, and we're seeing encouraging signs about other critical weapons: https://www.sciencemag.org/news/2020/05/t-cells-found-covid-19-patients-bode-well-long-term-immunity https://twitter.com/Tom18369195/status/1281615465110999042?s=20

As we've covered: These other weapons could play a crucial role for one of the leading COVID-19 vaccine candidates. https://on.natgeo.com/2Cpz4GI
That said, a small study reported recently that COVID-19 antibodies started fading after 2-3 months.
But even low amounts of antibodies can still be neutralizing, so I wouldn't give up on herd immunity yet. https://www.nytimes.com/2020/06/18/health/coronavirus-antibodies.html

Great question! I would start by peeping this new @NatGeo story by @heroinebook
It dives into the latest developments with airborne transmission and much more: https://on.natgeo.com/300mIgj https://twitter.com/UserGarmin/status/1281616406908473344?s=20

How long is coronavirus airborne? Hard to say right now
One study showed coronavirus-filled mist can linger for up to 16 hours. But this mist was created artificially, so it doesn't say much about what happens with actual coughs/sneezes https://wwwnc.cdc.gov/eid/article/26/9/20-1806_article

As @Sarah_Gibbens covered for us, a sneeze can expel respiratory droplets of various sizes 23 to 27 feet from a nose. https://on.natgeo.com/3elMOzE
This week, the World Health Organization reviewed all the evidence on airborne transmission and essentially came back with the same recommendation as before. ¯\\_(ツ)_/¯ https://on.natgeo.com/300mIgj
