. In the case of international migration, migrants have needs for housing and basic services, education, employment and social integration without a loss of cultural identity, and they are to be given adequate protection and attention within host countries.

And after the paracites have eaten away at the flesh of the hosts long enough, the hosts die.

migrants....are to be given adequate protection and attention within the host countries.

My dictionary gives three definitions for "host."
a) a man who entertains guests.
b) a man who keeps an inn or hotel.
c) an organism on or in which another lives.

I wonder which definition they had in mind.
