IQUIQUE, Chile (AP) — Chilean officials said Friday that water, fuel, electricity and other essential services are being re-established three days after a powerful magnitude-8.2 earthquake rattled the country’s far north. But pockets of poor people living in damaged homes, shantytowns and tents were still suffering the brunt of the disaster, and the hypothermia death of a newborn raised the quake’s toll to seven.

The government also issued a three-month health alert for the quake-hit regions. It grants officials more resources to avoid the spread of infectious diseases by coping with trash and contaminated water from rotting fish in port cities.
