thank you Mrs D, that's very reassuring. I think the CDC must be a US website as all NHS advice (I am in the uk) contra-indicates Hydroxychloroquine use for malaria prophylaxis due to resistance. It sounds as though I may well be ok with the hydroxy if I don't hear back from the hospital in time. My doctor has made the right moves to find out the answer for me but the hospital told her that they would manage things from here so, not surprisingly, she has left it in their capable hands . . . I, however, have only 3 working days until we go.

Thanks again. Clare
