LA GUAIRA, Venezuela (AP) – Aid groups warned Tuesday that Venezuela's fragile healthcare system is being pushed to its limits nearly a week after two powerful earthquakes, with damaged and understaffed hospitals overwhelmed by the injured and deteriorating conditions in the disaster zone causing infectious diseases to spread.

The scores of international and domestic teams across Venezuela remain focused on the search for survivors, with the government death toll surpassing 1,700 and new bodies still being hauled out from the rubble.

But a humanitarian crisis is already unfolding among the living.
