The story goes that swimmers in Florida beaches are getting “sea lice”. They are parasites.
HIV is also a parasite.
So is WN virus and Zika-dika-do virus.
I wonder why they don’t go and spray the ocean for parasites like they do mosquitoes and the human bloodstream?
Kill too much of everything else in that flowing body of water maybe?
Yeaaaaaa, that is the problem.
The blood stream is also a flowing body of water teaming full of things that we don’t want to kill.
Yet, we routinely treat it with chemical parasiticides.
