How civil society organizations can help tackle pandemics
World Economic Forum

July 15, 2021

COVID-19 has been the foremost global health challenge over the last year and a half and has affected all spheres of life and development. As of 7 July 2021, the world has registered a total of over 184 million COVID-19 cases, while confirmed deaths worldwide have been reported at over 3.99 million. It is envisaged that the Low and Middle Income Countries (LMICs) have been and will continue to be hit harder by the pandemic as a result of limited healthcare capacity and inadequate infrastructure, as well as difficulties in maintaining social distancing. Apart from its direct health consequences, COVID-19 has left communities in LMICs with dire economic consequences. The World Bank estimates that about 120 million people have been pushed into poverty due to COVID-19 in the last year or so.

Mental health a growing public priority in India
HelpAge International

January 05, 2016

Growing prevalence of mental health disorders in older populations is an emerging public health challenge in India. There are some 3.7 million people in the country currently living with dementia, according to Dementia India Report of 2010 (pdf). This figure is expected to double by 2030 and, with the number of older people projected to grow to 325 million by 2050, the country is at a great risk of an aggravated mental health challenge, while other conditions, including depression, delirium and anxiety, are also consistently rising. Particularly at risk are those older people living in remote, rural settings who, amid poverty, lack of literacy and poor health services, are especially vulnerable to mental health conditions.
