You're assuming too much. It's not adequate shelter. You'd get sick living in a shack in an indian slum or in a hut in the amazon without modern medicine plus expensive and time consuming precautions--precautions a slum dweller can't take. Read up on public health in slums, particularly slums in the tropics.

"many missionaries throughout history easily decided to go native"

Err, no. Missionaries (as well as soldiers and merchants) used to have crazy high mortality in the tropics.

I'm not assuming anything. I'm questioning what is the definition of adequate here, because whatever is the definition will determine whether or not I agree with the original statement.

Whether or not those housing conditions lend themselves to proper sanitation or not, missionaries decided to go native in spite of the high mortality, also knowing the mortality rate of their peers (until modern medicine came about to make things like malaria a much smaller concern). I don't see your point. Missionaries had a crazy high mortality in the tropics? So what? It didn't stop their decisions to go native. And they certainly didn't have a crazy high mortality rate after the arrival of modern medicine. What are you saying no to?
