John,

Sorry to hear about your loss. That is very sad.

One thing people forget or are not told is that the medications issued for Malaria do not prevent it. You can still get Malaria even if you take the pills. What they do is lessen the effect of the Malaria organism. In very high doses, these same meds are used to treat Malaria infections.

It is more or less a helpful and hopeful prevention, well worth taking rather than not.

There is no escape from Malaria unless the vector is eradicated and that has proven to be impossible in Africa and Central/South America.

Interestingly, at one time, even in the cold climate I live in Malaria was an epidemic.
