Certainly we can answer your questions about visitors insurance.
Pre-existing medical conditions are not covered under visitors insurance. Visitors insurance is for any new, unexpected sicknesses and injuries. However, we do offer travel medical insurance plans that provide coverage for acute onset of pre-existing conditions.
An Acute Onset of a Pre-existing Condition is a sudden and unexpected outbreak or recurrence of a pre-existing medical condition which occurs spontaneously and without advance warning either in the form of physician recommendations or symptoms. Treatment must be obtained within 24 hours of the sudden and unexpected outbreak or recurrence.
For example, if your father experienced a second heart attack while covered under visitors insurance, and had been following all of his doctor's instructions since the first one, the second heart attack would be covered under acute onset of pre-existing conditions.
