About 1,500 delegates from 57 countries attending the World Health Organization's Global Health Workforce Alliance meeting in Kampala, Uganda agreed Thursday to a plan of action to solve the alarming worldwide shortage of health workers.

The agreement contained in the Kampala Declaration and Agenda for Global Action sets out a series of steps to be taken by the 57 countries over the next 10 years. The steps the countries should take include training and recruiting sufficient health personnel and providing adequate incentives and better working conditions to ensure the retention of health workers.

WHO estimates the global shortage of health workers at four million. The UN agency said one million health workers are needed in sub-Saharan Africa alone.

The meet dubbed Global Forum on Human Resources for Health started on Sunday and runs up to Friday. Nearly 1,500 participants, including donors, experts and more than 30 ministers of health, education and finance attended the forum.
