Mozambique was hit especially hard. The government said that at least 400 people have died. Rescue workers say that thousands more may have been swept out to sea as the floodwaters rose. Their bodies may never be found.
At least 600,000 people have been displaced, according to the United Nations World Food Program, which deemed the crisis a level three emergency on par with war-torn Yemen, Syria and South Sudan.
Water and food are in short supply. The first cases of cholera have been reported by the Red Cross in Beira, a coastal city that bore the brunt of the storm. Aid efforts have been hampered by washed-out roads and bridges, leaving many residents to fend for themselves.
