South Korean President Park Geun-hye's job approval rating fell to an all-time low over the deadly MERS virus that has killed 24 people, a poll showed Friday.

A poll released by polling agency Gallup Korea showed 29 percent approved of the job Park is doing, down 4 percentage points from a week earlier.

Those who disapproved of Park's job performance came to 61 percent, up 3 percentage points from a week earlier.

It marked the third time that Park's job approval rating has sunk to 29 percent this year, South Korean News Agency (Yonhap) reported.

The government has been under fire for its poor initial response to the outbreak of the virus.

Park has repeatedly vowed to end the spread of the virus, but the poll results suggested that she failed to win back the public's confidence.

The survey was conducted on 1,000 adults between Tuesday and Thursday and had a margin of error of plus or minus 3.1 percentage points.
