I am a TBD Support Group Facilitator and one of the main tick borne diseases is Babesiosis. Babesiosis is a Babesia infection.

Just a heads up that locally we have had a dozen people over the years
with sleep apnea & Babesiosis and it has been noted in the literature as a symptom as well. So I would get tested for Babesiosis if you haven't been.
You probably haven't been.

It may be rare in some states- so far in California it is not rare- they did 3 complete serosurveys of communities (blood testing of whole communities)and found infection rates in people of 3.5%, 16% & 18%!! So it is basically an unknown epidemic in CA. on the East Coast it may be rarer but still worth ruling out because if your apnea is caused by this it is curable.

If you are in CA the strain is WA1, up & down the Pacific Coast it is WA1, stands for Washington 1, was found first in Washington State. So Oregon, WA, & CA you get tested for WA1. East Coast the strain is Babesia Microti.
Missouri there is MO1 and that is also in states around Missouri and in Kentucky and in Mass.

Just a note- it may be that your docs already tested you so just ask them, they may not know it can cause it though so it is worth asking!
Just a note,
Best wishes,
Sarah
