Cases of cholera in Mozambique soared to 517 people in Sofala province, the government of Mozambique said Sunday, while announcing that a first cholera fatality is now reported in the hard-hit port city of Beira. The cholera spike, feared in the wake of devastating Cyclone Idai, has prompted officials to begin mass vaccinations for the entire population of Beira, home to about a half million people prior to the storm. They’ll also be given to at-risk groups in parts of Dondo, Búzi and Nhamatanda, according to health officials. So far, 11 cholera treatment centers – five of them in Beira – have been set up. More than 500 people have died in the two weeks since the storm in Mozambique, with 245 additional fatalities in the neighboring nations of Malawi and Zimbabwe. Idai made landfall on March 14 near Beira with sustained winds of 175 kilometers (109 miles) per hour and gusts of 213 km/h and heavy rainfall, along with life-threatening storm surge. The system stalled over a region already damaged by floods during its first pass in early March. In Beira, about 80 percent of the city’s infrastructure has been destroyed. Electricity has been restored to some parts of the city including the hospital, and about 60 percent of the water system is working. President Filipe Nyusi has promised a comprehensive aid plan, including the suspension of any health care fees, free seeds and tools for farming, and redistributed books and other school materials. Some rail fares have been cut by 50 percent, as have electric utility costs. Nyusi said 1.8 million people have been affected by the storm, more than 800,000 of them directly, according to surveys and satellite imagery.
