The rapid spread of monkeypox across non-endemic regions has stressed healthcare systems worldwide, particularly ICUs, which are dealing with severe cases. Recent research reveals significant insights into the virus’s transmission, the growing burden of hospitalization, and the need for updated vaccination and treatment protocols. Understanding these developments is essential to mitigating future outbreaks and ensuring patient safety.
01 Monkeypox Outbreaks: Global Spread and Severe Health Impacts
Recent reports have documented the rapid spread of monkeypox, with the virus reemerging in non-endemic regions like North America and Europe. Over 15,000 cases were reported globally in 2023 alone, with the World Health Organization (WHO) categorizing monkeypox as a public health emergency of international concern. Particularly alarming is the virus’s spread among vulnerable populations, such as men who have sex with men (MSM), who accounted for 98% of cases in Europe during the 2022 outbreak. At the same time, healthcare systems in endemic regions like Africa remain under-resourced, struggling to manage the increasing caseload.
Hospitals in both non-endemic and endemic regions have been overwhelmed by severe cases requiring ICU admissions, especially for complications involving the cardiovascular and neurological systems. According to data from the 2022 outbreaks, approximately 12% of hospitalized monkeypox patients required intensive care, underscoring the virus’s ability to cause significant morbidity. These developments emphasize the need for improved research into treatment protocols and enhanced patient safety in managing the virus.
02 Investigating the Cardiovascular Impacts of Monkeypox
Figure 1: Cardiovascular Manifestations of Monkeypox Virus Outbreak: An Overview of the Reported Cases
Building on the observation that hospitals are grappling with severe complications from monkeypox cases, the paper ‘Cardiovascular Manifestations of Monkeypox Virus Outbreak: An Overview of the Reported Cases’ analyzed 76 confirmed cases of myocarditis and pericarditis in monkeypox patients during the 2022 outbreak. Approximately 10% of monkeypox patients developed cardiovascular issues, with 6% experiencing myocarditis and 4% suffering from pericarditis. This is particularly concerning for patients with pre-existing conditions like HIV, where cardiovascular complications can significantly increase mortality risk.
Figure 2: Hospitalization Determinants in Patients with Mpox Disease: The CEME-22 Project
The CEME-22 Project, which reviewed 255 monkeypox patients across multiple hospitals, found that 22% of hospitalized patients had gastrointestinal complications, while 18% had severe neurological symptoms. These factors were the leading contributors to ICU admissions, alongside cardiovascular symptoms. The findings indicated that patients with comorbid conditions, such as diabetes or respiratory issues, were twice as likely to require ICU care, highlighting the importance of early intervention and specialized treatment for high-risk groups.
Figure 3: Images in Clinical Medicine: Monkeypox with Genital Ulcer as the First Symptom
Linking this to early detection challenges, the paper ‘Images in Clinical Medicine: Monkeypox with Genital Ulcer as the First Symptom’ reported that 14% of patients presented with genital ulcers as the initial symptom of monkeypox. This atypical symptom delayed diagnosis in many cases, leading to a higher risk of complications. The case study highlighted that these patients required longer hospital stays and were at greater risk of developing secondary infections due to delayed treatment.

Further complicating hospitalization decisions, ‘Pharmacological treatment and vaccines in monkeypox virus: a narrative review and bibliometric analysis’ revealed that patients with HIV were three times more likely to require ICU care due to immune suppression. This correlation between immunosuppression and severe outcomes underscores the need for targeted interventions in these vulnerable populations, reinforcing the importance of rapid diagnosis and appropriate care for patients with pre-existing conditions.
03 What: The Origins, Spread, and Management of Monkeypox
Figure 5: Monkeypox: A Potential Global Threat?
The paper ‘Monkeypox: A Potential Global Threat?’ explored the zoonotic origins of the virus, linking its spread to increased human-animal contact in rural areas. With over 70% of reported cases traced back to direct or indirect contact with infected animals, the paper warns that unless comprehensive surveillance measures are put in place, monkeypox could continue to spread globally, particularly as deforestation and urbanization increase these interactions.
Figure 6: Monkeypox: An Emerging Disease
The paper ‘Monkeypox: An Emerging Disease’ highlights how the termination of smallpox vaccination programs in 1980 has resulted in a population susceptible to monkeypox. Vaccinated individuals are estimated to have an 85% reduced risk of monkeypox infection. The paper calls for renewed vaccination efforts, particularly in high-risk groups, noting that the lack of immunity is a primary driver of the recent outbreaks.
Figure 7: The 2022 Human Monkeypox Outbreak: Clinical Review and Management Guidance
The study ‘The 2022 Human Monkeypox Outbreak: Clinical Review and Management Guidance’ provides an overview of clinical features, noting that 68% of cases presented with skin lesions, while 30% experienced fever and flu-like symptoms. The paper emphasizes the importance of developing standardized treatment protocols to manage these symptoms, which will be crucial in preventing complications during future outbreaks.
Figure 8: Will Monkeypox Outbreak Mirror COVID-19 or AIDS?
The paper ‘Will Monkeypox Outbreak Mirror COVID-19 or AIDS?’ compares the trajectory of the monkeypox virus to previous pandemics. Although monkeypox is less transmissible, it has been shown to have a reproductive number (R0) of less than 1, meaning it is unlikely to spread as rapidly as COVID-19. However, the paper warns that complacency could lead to the virus becoming endemic in new regions if proper preventive measures are not implemented.
Figure 9: Pharmacological Agents with Antiviral Activity Against Monkeypox Infection
Finally, the paper ‘Pharmacological Agents with Antiviral Activity Against Monkeypox Infection’ reviews the use of tecovirimat in treating severe cases. Tecovirimat was administered to over 300 patients during the 2022 outbreak, with 87% showing clinical improvement within two weeks. This paper highlights the need for further research into antiviral treatments as the demand for effective therapies continues to rise.
04 Looking Forward: Global Health Preparedness and Future Developments
Based on recent studies, the need for targeted interventions becomes evident. For example, tecovirimat has shown efficacy in treating severe cases, especially in vulnerable populations, as discussed in ‘Pharmacological Agents with Antiviral Activity Against Monkeypox Infection.’ Data from the CEME-22 Project highlights that patients with comorbidities and immunosuppression require intensive care more often, aligning with the findings about cardiovascular complications in patients with conditions like HIV. With hospitalization rates influenced by such factors, investing in better ICU support is essential for managing future outbreaks.
The role of vaccinations is equally significant. As mentioned in ‘Monkeypox: An Emerging Disease,’ the decline in smallpox vaccination has left the global population more susceptible. Research shows that vaccination campaigns targeting high-risk groups, such as those immunocompromised or in regions with limited healthcare infrastructure, will be crucial in minimizing future outbreaks. Surveillance systems and treatment protocols will need to evolve with the virus to ensure that healthcare systems can respond effectively to the growing threat.
