Bites after trip out of the country

tkkk

I recently went to St Lucia in the Caribbean. I got home 3 days ago, and these bites seem to be getting worse and more are appearing. They itch really bad!

I thought just mosquito bites... but they are all in a line following my underwear? Like an exact line.

Sorry for the pictures, I tried! Lol.

We did have mosquito nets. And these are my ONLY bites I’ve gotten. Not one anywhere else. No one on the trip that went with us has these either.
