As Covid-19 captures global headlines, the World Health Organization (WHO) warned yesterday that the world needs nearly six million nurses.

The UN's health agency along with partners Nursing Now and the International Council of Nurses (ICN) underscored in a report the crucial role played by nurses, who make up more than half of all health workers worldwide.

"Nurses are the backbone of any health system," WHO chief Tedros Adhanom Ghebreyesus said in a statement.

"Today, many nurses find themselves on the frontline in the battle against Covid-19," he noted, adding that it was vital they "get the support they need to keep the world healthy."

The report said that there are just under 28 million nurses on the planet. In the five years leading up to 2018, the number grew by 4.7 million, reports AFP.

"But this still leaves a global shortfall of 5.9 million," the WHO said, pointing out that the greatest gaps were in poorer countries in Africa, southeast Asia, the Middle East and parts of South America.

The report urged countries to identify gaps in their nursing workforce and invest in nursing education, jobs and leadership.

Meanwhile, a spokesman said yesterday World Health Organization has no blanket recommendation for countries and regions for easing measures to slow the spread of the coronavirus pandemic, but urged them not to lift them too early, reports Reuters.

"One of the most important parts is not to let go of the measures too early in order not to have a fall back again," said WHO spokesman Christian Lindmeier in a virtual briefing.
