There is another type of this worm that is found in South America. They have mass doesed Ivermectin there and created a very resistant strain.
I beleive, though have NO proof, that I or my husband picked up this strain while in California or Florida since many of the same migrant workers that get it in South America move to both Florida and California where we have been.
We also have worms in our sinuses and we can see evidence of filaria in the worms we have looked at under the microscope. If you think you could have these worms, or any filarial worm, you should immediately get doxycyline because that is the best hope of actually ridding yourself of them eventually.
Doxycycline interrupts most of the filarial worms' ability to reproduce through killing a bacteria they depend upon to do so. Google filaria and you will find the research or search this site.
