Kenya's mpox outbreak remains a major public-health concern, with the latest reports showing that the number of confirmed infections has risen to 1,298 cases, while the Ministry of Health is urging Kenyans to strengthen preventive measures. The government has also identified seven counties as high-risk areas as the outbreak continues to spread across the country. Today's reports indicate that mpox has now been detected in 40 counties, demonstrating how the outbreak has moved well beyond the areas initially affected in 2024. 

The latest development is significant because Kenya's mpox outbreak has been ongoing for more than two years. The country's first confirmed case was reported on 31 July 2024, and the outbreak initially involved cases connected to travel and the major transport corridor between Mombasa and the Kenya-Uganda border. Since then, transmission has expanded to many counties, prompting the Ministry of Health to maintain surveillance and strengthen prevention efforts.

Seven counties now flagged as high-risk

One of the biggest developments in today's news is the Ministry of Health's decision to flag seven counties as high-risk areas for mpox.

The identification of high-risk counties is important because health authorities can concentrate surveillance, public education, testing and other interventions in areas where the possibility of continued transmission is considered greater.

Nairobi is among the counties receiving particular attention. As Kenya's capital and largest urban centre, Nairobi has a large and highly mobile population. People regularly travel into and out of the city for employment, business, education, healthcare and other activities. This mobility can make infectious-disease control more complicated.

The government is therefore encouraging residents not to panic but to take the recommended preventive measures seriously.

Kenya records 1,298 mpox cases

Today's reports indicate that Kenya has recorded 1,298 confirmed mpox cases. The figure represents a substantial increase from the numbers reported during the earlier stages of the outbreak.

The Kenya Broadcasting Corporation reported today that the Ministry of Health is urging Kenyans to strengthen hygiene and preventive measures following the rise in cases. 

Another report published today puts the number of deaths at 19, highlighting that although many people recover from mpox, the disease can become serious and potentially fatal in some circumstances. 

The increase in cases is a reminder that mpox should not be viewed as an issue that ended after the initial outbreak in 2024. Kenya continues to require surveillance and public-health interventions.

 *How Kenya's outbreak began* 

Kenya confirmed its first mpox case in July 2024. The initial case was detected at the Taita Taveta one-stop border point, highlighting the importance of border surveillance in controlling infectious diseases. 

At the beginning of the outbreak, authorities were particularly concerned about Kenya's busy transport routes.

The country's Northern Transport Corridor connects the port of Mombasa with western Kenya and the border with Uganda. It is an important commercial route used by thousands of people and vehicles.

WHO reported in September 2024 that Kenya's national mpox preparedness and response plan identified 14 high-risk counties along the Northern Corridor, with rapid response teams deployed to intensify surveillance. 

Research by the U.S. Centers for Disease Control and Prevention later showed the importance of this transport route. Among 48 laboratory-confirmed clade Ib mpox cases investigated in Kenya between July 2024 and February 2025, 27 cases, or 56.3%, occurred among truck drivers or their contacts along the Mombasa–Malaba highway. 

This does not mean that truck drivers caused the outbreak. Rather, their frequent movement between different communities and countries meant that the transport corridor became an important location for surveillance and prevention.

The outbreak is now much wider

The current situation is very different from the early stages of the outbreak.

Instead of being concentrated around a few transport-linked locations, mpox has now been reported in 40 counties, according to today's reports. 

This geographical expansion means that county health departments across Kenya need to remain alert.

The spread also demonstrates why communities need accurate information. A person does not have to be a truck driver, traveller or member of any particular group to contract mpox.

The virus can infect anyone following close contact with an infected person.

 *What exactly is mpox?* 

Mpox is a viral infection caused by the mpox virus, which belongs to the Orthopoxvirus family.

The disease was previously known as monkeypox, but the World Health Organization adopted the name "mpox."

The disease commonly causes a rash or lesions. Other symptoms can include fever, headache, muscle aches, fatigue, sore throat and swollen lymph nodes.

The lesions can be painful and can occur on different parts of the body. Depending on how a person becomes infected, lesions may occur around the face, mouth, hands, feet or genital and anal areas.

Not every person develops exactly the same symptoms. Some people have relatively mild illness, while others develop more serious complications.

How mpox spreads

Understanding transmission is one of the most important ways Kenyans can protect themselves.

Mpox can spread through close physical contact with an infected person.

Contact with lesions, scabs or bodily fluids can transmit the virus. The infection can also spread through contaminated materials such as clothing, bedding and towels.

Sexual contact has been an important transmission route in some outbreaks, but mpox should not be described as exclusively a sexually transmitted infection. Close non-sexual physical contact can also result in transmission.

This is why stigma can be harmful. Assuming that only people from a particular group can contract mpox may cause other people to ignore symptoms and delay seeking medical care.

Symptoms to watch for

Kenyans should be familiar with the common symptoms of mpox.

They include:

Fever

Headache

Muscle and body aches

Swollen lymph nodes

Fatigue

Sore throat

Skin rash

Painful lesions

Fluid-filled or crusted lesions

The rash can develop in different areas of the body.

People should not automatically assume that every skin rash is mpox because many other illnesses can cause rashes. However, an unexplained rash accompanied by fever, swollen lymph nodes or a history of close contact with an infected person should be medically assessed.

Anyone experiencing concerning symptoms should visit a health facility rather than relying on self-diagnosis.

Why the government is urging Kenyans to improve hygiene

The Ministry of Health's latest message focuses strongly on prevention and hygiene.

This is particularly important because people may come into close contact with one another in public places, workplaces, schools, public transport, markets and other crowded environments.

Regular handwashing with soap and water is a simple measure that can help reduce the spread of many infectious diseases.

People should also avoid touching the lesions of someone who may have mpox and should not share personal items such as towels, clothing or bedding with an infected person.

People with confirmed infection should follow medical advice about isolation and preventing transmission to household members.

Kenya's vaccination response

Vaccination has also been part of Kenya's response.

In September 2025, Kenya conducted its first mpox vaccination campaign in Mombasa, Busia and Nakuru. WHO reported that the 10-day campaign reached more than 10,600 people. 

The vaccination programme targeted people considered to be at higher risk of exposure.

The availability of vaccines has been an important development because African countries faced significant challenges accessing mpox vaccines during the earlier stages of the outbreak.

Kenya is also expected to benefit from a new international mpox vaccine stockpile. A report published on 4 September 2026 said the new stockpile is intended to help countries obtain vaccines more quickly when outbreaks occur. 

Gavi reported on 3 September that the global stockpile is expected to create a longer-term mechanism for providing rapid and equitable access to mpox vaccines during outbreaks. 

This could become particularly important for countries such as Kenya where transmission remains a concern.

 *Why Nairobi is an important area to watch* 

Nairobi's inclusion among the high-risk counties is particularly significant.

The city is Kenya's main economic and transportation hub and has a very large population. People arrive in Nairobi from almost every part of the country, while international travellers also pass through the city.

This high level of movement makes surveillance important.

However, residents should not interpret the high-risk designation as meaning that everyone in Nairobi is in immediate danger. Instead, it means that health authorities are paying closer attention to transmission and want people to take preventive measures seriously.

Mpox and stigma

Another important issue during today's outbreak is the need to avoid stigma.

Mpox can affect people from different backgrounds. Focusing excessively on particular occupations or sexual behaviours can discourage people from seeking help.

When someone develops symptoms, the priority should be getting medical advice, testing where appropriate and preventing further transmission.

People should not be mocked, discriminated against or publicly identified because they have or are suspected of having mpox.

A supportive environment encourages people to report symptoms early, which helps health authorities control outbreaks.

Kenya's experience with surveillance

Kenya has strengthened its ability to detect outbreaks through disease surveillance.

An example occurred in Nairobi in March 2026, when an mpox alert was reported through Kenya's m-Dharura digital disease-reporting platform. Health authorities responded quickly, investigated the situation and introduced hygiene interventions. No additional mpox cases were identified after the response, suggesting that the cluster was successfully contained. 

This demonstrates why early reporting is important.

A suspected case that is reported quickly can be investigated before transmission expands to many more people.

Why the latest figures matter

The rise to 1,298 cases shows that Kenya's mpox outbreak remains active.

The situation also illustrates how an outbreak can evolve. Kenya began with a relatively small number of cases in 2024, but transmission subsequently expanded geographically.

Today's figure should therefore encourage continued vigilance rather than panic.

It is also important to understand that reported confirmed cases are not necessarily the same as the total number of people who have been exposed or infected. Testing and reporting systems may not identify every infection, especially when people have mild symptoms or do not seek medical attention.

This is one reason public-health authorities continue to emphasise surveillance.

 *What Kenyans should do now* 

The Ministry of Health's advice can be translated into several practical actions.

First, maintain good hygiene. Wash your hands regularly with soap and water.

Second, avoid unnecessary close contact with people who have unexplained rashes or suspected mpox.

Third, do not share personal items such as towels, clothing or bedding with someone who is infected.

Fourth, seek medical attention if you develop symptoms. Do not attempt to hide the illness or depend entirely on social-media information.

Fifth, follow vaccination advice. People who are considered eligible for vaccination should follow instructions from health authorities.

Sixth, avoid stigma. Anyone can potentially contract an infectious disease, and people who are ill need medical support rather than discrimination.

 *What happens next?* 

The government's immediate priority is likely to remain surveillance, prevention, testing and public awareness, particularly in the seven counties identified as high-risk.

The fact that the outbreak has reached 40 counties means that county governments and national health authorities will need to work together.

Border surveillance will also remain important because Kenya is connected to several neighbouring countries where infectious diseases continue to circulate.

The international vaccine stockpile announced this month could provide additional support by making it easier for affected countries to access doses when needed.
