Jan 22 (Reuters) - Zimbabwe's finance minister expressed

concern on Wednesday that a U.S. withdrawal from the World

Health Organization will lead to aid cuts to countries such as

his that are most affected by HIV/AIDS.

President Donald Trump signed an executive order on the U.S.

withdrawal after his inauguration to a second term on Monday.

Warning that a U.S. withdrawal could signal cuts in health

aid to countries such as Zimbabwe, Finance Minister Mthuli Ncube

said: "Any country with an HIV/AIDS challenge will be impacted."

"This is a concern, a fear we are expressing," Ncube told

an online briefing from the Swiss resort of Davos, where was

attending the World Economic Forum.

Zimbabwe receives over $200 million annually from the U.S.

President's Emergency Plan for AIDS Relief (PEPFAR), and the U.S

government has given Zimbabwe over $1.7 billion since 2006 to

strengthen health systems and support people living with HIV,

according the U.S. embassy in Harare.

PEPFAR contributes nearly $90 million a year to support

salaries and incentives for healthcare workers in Zimbabwe, in

addition to funding HIV and viral load testing, prevention,

cervical cancer screening and tuberculosis treatment.

Zimbabwe is struggling to fund its public health system, and

the government introduced a sugar tax on beverages last year to

help raise funds for cancer treatment. Another tax on fast foods

was introduced this year.

"We need to scale up our funding for health. The earmarked

taxes should be directed towards health as we build our capacity

to fill the gap should any funding recede," Ncube said.
