“For admitted patients there was an increase from 51,641 in 2010 to 68,158 by 2017, which is an increase of 32 per cent,” the president explained.
“So far, the government has managed to control malaria disease, the infection stands at 0.4 per cent while at the same time the government has taken strong measures to control HIV/AIDS, which is now at 0.4 per cent,” he said.
