Claims have been made that simply being in sea water near a beach exposes you to the possibility of COVOD-19 infection:
In a Los Angeles Times interview early last week, [Kim] Prather was quoted as saying, “I wouldn’t go in the water if you paid me $1 million right now.” She posited that SARS-CoV-2, the virus that causes COVID-19, could enter the ocean — through raw or poorly treated sewage — and then get kicked back into the air along the surf zone.
Prather later walked back her statement, saying that ordinary polluted water was the problem, regardless of the virus. But the COVID/sea water claim is still being bounced around on the internet.
It seems to me that any virus that gets into sea water would be rapidly deactivated, if not by the salt water itself then by the pollutants in the water and sunlight. Plus getting greatly diluted virus particles out of the water and into the air in sufficient quantities to represent a significant risk seems unlikely.
So is there any reasonably significant probability that COVID-19 virus particles could be "washed" into sea water and then somehow aerosolized in sufficient quantities to represent a hazard to a person on the beach or in the water?
