Sierra Leone declares state of emergency in response to its second reported case of mpox within just four days, signaling growing concern over the rapid spread of this infectious disease.
Health authorities in the country have taken swift action to contain the outbreak, with both identified patients currently receiving treatment in Freetown, the capital city.
The situation underscores the seriousness of the threat posed by a new and more transmissible strain of the virus that has already triggered global health alarms.
Mpox: A Global Health Challenge
Mpox, formerly known as monkeypox, is a zoonotic viral disease that has recently surged in prevalence. The World Health Organization (WHO) declared the outbreak a global health emergency in August 2024 due to the rapid spread of a new strain that is more transmissible and causes severe symptoms.
The virus manifests with symptoms such as fever, headaches, and painful boils on the skin. It spreads through close physical contact, including sexual contact, and has raised significant public health concerns worldwide.

While outbreaks of mpox have historically been linked to contact with infected animals, the current cases in Sierra Leone are unusual, as neither of the two patients had known exposure to infected animals or individuals.

This newly circulating strain has proven particularly concerning. Unlike the mpox outbreak in 2022, which predominantly affected men and was brought under control through targeted vaccination campaigns, the current strain appears to affect a broader demographic and causes a more severe version of the disease.
Sierra Leone’s Public Health Response
Sierra Leone’s declaration of a state of emergency comes as the nation seeks to prevent a full-blown outbreak. With memories of the devastating 2014 Ebola crisis still fresh, authorities are prioritizing swift containment measures to protect public health.
The two confirmed cases have prompted heightened surveillance efforts, contact tracing, and public awareness campaigns to educate citizens about the symptoms and transmission of mpox. Health officials are focusing on early detection and isolation of cases to curb the virus’s spread.
Sierra Leone is no stranger to public health emergencies. The country served as the epicenter of the 2014 Ebola outbreak, which claimed thousands of lives and overwhelmed the healthcare system. That experience has shaped its current approach, with lessons learned from Ebola guiding the government’s response to mpox.
The declaration of a public health emergency allows for the mobilization of additional resources and international support. Local health workers are being trained to manage the outbreak, and the government is working closely with the WHO and other global health organizations to secure vaccines and medical supplies.
The African Context and Global Implications
While Sierra Leone has reported only two cases thus far, the situation is part of a broader public health challenge facing the African continent. The Democratic Republic of the Congo (DRC) has borne the brunt of the ongoing mpox outbreak, with over 43,000 suspected cases and 1,000 deaths reported.
The new strain’s high transmissibility and severity have exacerbated the crisis in central Africa and raised concerns about its potential to spread to other regions. The re-emergence of mpox underscores the importance of global collaboration in addressing zoonotic diseases.
As with Ebola, localized outbreaks can quickly become international crises without timely intervention and resource allocation. The WHO’s declaration of a global health emergency highlights the need for coordinated efforts to combat the virus and mitigate its impact.
Vaccination campaigns targeting vulnerable populations have proven effective in controlling previous outbreaks, and similar strategies are being considered for the current strain. Public health experts emphasize the importance of equitable access to vaccines, particularly in low-income countries like Sierra Leone, where healthcare resources are limited.
Lessons from the Past and the Path Forward
The mpox outbreak in Sierra Leone serves as a stark reminder of the interconnectedness of global health and the need for vigilance in detecting and responding to emerging infectious diseases. The country’s experience with Ebola has prepared it to some extent, but challenges remain, particularly in terms of healthcare infrastructure and public awareness.
For Sierra Leone, the priority now is to contain the virus and prevent further transmission. This involves not only treating the infected but also addressing the underlying factors that contribute to outbreaks, such as limited access to healthcare, inadequate sanitation, and a lack of public health education.
On a global scale, the mpox outbreak highlights the need for continued investment in research, surveillance, and vaccine development. It also underscores the importance of strengthening healthcare systems in vulnerable regions to ensure they are better equipped to handle future crises.
As Sierra Leone grapples with this new challenge, its response will serve as a case study in the importance of preparedness, collaboration, and resilience in the face of public health emergencies.
By addressing the current crisis with urgency and determination, the country can not only protect its citizens but also contribute valuable lessons to the global fight against zoonotic diseases.
let’s enjoy few years on earth with peace and happiness….✍🏼🙏
