UNITED NATIONS, April 7 (Xinhua) -- UN Secretary-General Antonio Guterres spotlighted the importance of universal health coverage to mark the World Health Day, which falls on Sunday.

In his message for the day, Guterres pointed out that half the world's population is still unable to obtain the essential health services they need.

He added that universal health coverage is about changing the situation and ensuring equitable access to health services for all without people experiencing financial hardship as a result.

To achieve the goal, Guterres stressed the need to investment "in people" for trained and skilled health workers and communities with access to health care.

He also highlighted the importance of mental health, "so often stigmatized and forgotten."

"Health is a human right," he stressed in the message delivered on Thursday. "Political commitment and partnerships will be crucial in bringing it to life."

In closing, the UN chief urged "let us show the world that we are ready to bridge the gaps in health-care coverage worldwide and deliver health for all."

The 2019 World Health Day focuses on universal health coverage and the crucial role primary health care plays in making such coverage a reality.
