Nairobi County has recorded the highest number of new HIV infections in the country, according to fresh data from the National Syndemic Disease Control Council.
The figures show that new infections rose by 19 per cent over the past year, climbing from 16,752 to 19,991. Ten counties accounted for sixty per cent of all new infections in 2024, led by Nairobi with 3,045 cases, followed by Migori with 1,572 and Kisumu with 1,341.
The Council noted that the heavy concentration of new infections in these counties highlights persistent regional disparities and underscores the need for targeted county level interventions.
The Kenya HIV Estimates report placed the national HIV prevalence at three per cent in 2024. The rate was higher among females at four per cent compared to two per cent among males. The report also confirmed an increase in HIV related deaths, rising from 18,473 in 2023 to 21,007 in 2024.
Health Principal Secretary Ouma Oluga said the deaths are a reminder of the need to prioritise early diagnosis, adherence to treatment and keeping patients in care.
NSDCC data further shows that Kenya recorded a significant reduction in new infections in 2025, with a fifty two per cent decline. As of 2024, the country had 1,326,336 people living with HIV, including 62,798 children. The burden of new infections was found to be highest among young people aged fifteen to thirty four, who continue to represent the majority of new cases each year.
Some counties, including Elgeyo Marakwet, Wajir, Mandera, Kisii, Machakos, Kericho, Uasin Gishu, Nakuru, Bomet, Baringo, Trans Nzoia and Laikipia, reported major improvements. These regions recorded a seventy five per cent drop in new HIV infections, signaling progress in prevention efforts and wider access to treatment.
