Kenya Mpox Cases Surge Across Forty Counties

NAIROBI, KENYA — Kenya has confirmed 1,298 Mpox cases with 19 deaths across 40 counties as of 6 September 2026. The Kenya Mpox cases surge has prompted the Ministry of Health to strengthen disease surveillance along major transport corridors and call for heightened community prevention efforts across East Africa’s largest economy.
Public Service Secretary Mary Muthoni urged citizens to maintain strict hygiene practices and report early symptoms, including fever, muscle pain, swollen lymph nodes, and distinctive skin lesions.
Epidemiological Burden Across High-Risk Transport Corridors

Surveillance and Response Measures for the Kenya Mpox Cases Surge
The Kenya Public Health Institute and county health departments are conducting epidemiological investigations and contact tracing in high-transmission areas. Healthcare workers are receiving enhanced infection control training to limit hospital-acquired infections, supported by technical assistance from the World Health Organization.
Furthermore, the upcoming Kenya Public Health Institute Conference (KEPHIC 2026, October 26–29 in Nairobi) will center on scaling up primary healthcare response mechanisms.
Why It Matters: Addressing the Kenya Mpox cases surge mitigates regional transmission risks that threaten healthcare infrastructure across East Africa’s interconnected trade corridors.
