Starting in 2012 i subscribe April international insurance for my 3 child's, and nothing special to declare to them at that time, when complete the questionnaire.
Fortunately, i never have to used those insurance for any of them, until this year 2016, when few weeks ago, my little one, has to be admit in hospital with high fever because of urine infection.
After all test was done, we discover that she had some problem with her right kidney, and surgical intervention was recommended.
Unfortunately, April international" not cover those intervention, and all was under my cost.
so, i advise of all you to look to other insurance, or if you are with "April"...stay in good health.
