Some 160 people get infected with HIV daily at the Coast, according to the National Aids Control Council.
A report by the council showed that youths aged between 18 and 24 years were the most affected.
Boda Boda riders and homosexuals are also leading in the newest HIV infections, the survey shows.
National Aids Control Council Coast Coordinator Julius Koome attributed the trend to unprotected sex.
Annually, the region records 61,000 new infections, he added. “The statistics are so worrying. We are finding measures to prevent new infections,” he said.
