Nairobi, July 1 : The World Health Organisation (WHO) has said it's intensifying its operations to the looming health crisis in eastern Africa amid acute food insecurity. Ibrahima Soce Fall, WHO Assistant Director-General for Emergency Response, said on Thursday that the health risks in the region are increasing while access to healthcare is deteriorating. "The cost of inaction is high. While the clear priority is to prevent people from starving, we must simultaneously strengthen our health response to prevent disease and save lives," he added in a statement issued in Nairobi, the capital of Kenya. Fall was earlier this week in Nairobi where WHO convened a two-day meeting to plan its response across the seven countries affected by the health emergency -- Djibouti, Ethiopia, Kenya, Somalia, South Sudan, Sudan and Uganda -- and coordinate with other UN agencies and partners, Xinhua news agency reported. The UN health agency said its setting up a hub in Nairobi, from where it will coordinate the response and organise the delivery of life-saving medical supplies to where they are needed most. These supplies, it said, include medicines, vaccines, as well the medicines and equipment needed to treat children who are severely malnourished. WHO said the eastern African region faces acute food insecurity, the worst in 40 years, caused by conflict, extreme weather events induced by climate change, rising international food and fuel prices and the impact of the pandemic. The UN health agency added that its emergency response is focused on ensuring affected populations can access essential health services, treating sick children with severe malnutrition, and preventing, detecting and responding to infectious disease outbreaks. WHO said it's also working with Health ministries in the affected countries to set up robust disease surveillance systems to be able to quickly detect and respond to disease outbreaks. /IANS
