Local health officials in Fangak said initial samples from the sick returned negative results for cholera. Sheila Baya, a spokesperson for the WHO spoke to the BBC, saying the team of scientists had to reach Fangak via a helicopter due to the flooding. She added that the group is waiting for transport to return them to the capital Juba on Wednesday. She said: “We decided to send a rapid response team to go and do risk assessment and investigation. “That is when they will be able to collect samples from the sick people – but provisionally the figure that we got was that there were 89 deaths.” Most read in News GAS SCARE Hundreds of people evacuated from London's main tourist area over gas leak fear THE LION CLING Incredible moment lioness goes in for a HUG with her human best friend FACING THE DOCK US diplomat's wife Anne Sacoolas to face UK court over Harry Dunn's death LAWN AND ORDER 'Britain’s worst garden makeover' so bad landscaper was taken to COURT VAXX TO THE FUTURE Brits will need 3 jabs for vaccine passports from as early as February SALT IN THE WOUNDS Salt Bae's restaurant now among lowest-ranked in London on TripAdvisor The minister of land, Lam Tungwar Kueigwong said that severe floods have increased the spread of diseases such as malaria and caused malnutrition in children due to food shortages across the northern states. Oil from the fields in the region had contaminated the water, he said, leading to the death of domestic animals. International charity Médecins Sans Frontières, which operates in the area said the suffering caused by the floods, including food shortages and illnesses, is putting pressure on the health facilities. They said: “We are extremely concerned about malnutrition, with severe acute malnutrition levels two times the WHO threshold. “The number of children admitted to our hospital with severe malnutrition doubling since the start of the floods.” Nearly a decade after South Sudan gained independence following a war, it faces the threat of conflict, climate change and COVID-19, the outgoing head of the U.N. mission in the country said in March. Nearly all the population depends on international food aid, and most basic services such as health and education are provided by the United Nations agencies and aid groups.
