This was made known by Transparency International survey released on Tuesday.
According to the report, 83 percent of South Africans interviewed felt that corruption had increased, with Ghana and Nigeria also among the worst-affected nations.
Across all 28 countries surveyed, the police, business executives, government officials and the courts were all perceived as corrupt, with 75 million people estimated to have paid a bribe in the past year.
The survey also said that during the deadly Ebola outbreak in Liberia and Sierra Leone, corruption may have contributed to the slow government response.
“In both of these countries there are very high bribery rates and the public sector is perceived to be affected by extensive levels of corruption,” said the survey.
On the plus side, Botswana scored well, with 54 percent indicating that their government was doing well in combating graft.
Only 20 percent of South Africans said they felt the same.
Madagascar ranked bottom, at nine percent, on the government’s commitment to fight corruption.
