We received an alarming email from a reader very recently and decided we must address it before some of the other questions that have accumulated (even though we will get to all them). The reader claimed to have screw worms – that is, she is infected with screw worms (sometimes spelled as one word, “screwworms”) – and she is obviously quite concerned about this. She is wondering what she should do, and the answer we give to someone with a screw worm infection is the same answer we give to anyone with a medical condition: seek medical care. Worms are our forte, so we certainly know a bit about screw worms, but anything we say should not in any way be construed as medical advice. That said, we can supply a little information about screw worms and the problems they cause, and it may be of assistance to our reader with the (potential) screw worm infection (but, again, it should absolutely not replace medical care).
