Diabetes mellitus: Lessons from COVID-19 for monkeypox infection.

BACKGROUND AND AIMS: Type 2 Diabetes Mellitus is known to be linked to malfunctioning antiviral defense; however, its association with the severity of monkeypox is poorly understood. In this review, we discuss key immunological mechanisms in the antiviral response affected by poor glucose control that could impact the susceptibility and severity of monkeypox infection, leading to a heightened emphasis on the use of the available antidiabetic drugs. METHODS: We searched PubMed and Google scholar for articles published from January 1985 to August 2022. No criteria for publication data were set, and all articles in English were included. RESULTS: Currently, there are no studies about the risk or consequences of monkeypox infection in the diabetic population. A high incidence of diabetes is reported in countries such as China, India, Pakistan, EUA, Indonesia, Brazil, Mexico, Bangladesh, Japan, and Egypt, where unfortunately imported cases of monkeypox have been reported and the infection continues to spread. CONCLUSIONS: High incidence of diabetes together with the cessation of smallpox vaccination has left large numbers of the human population unprotected against monkeypox. The best option for the population remains confined to the prevention of infection as well as the use of hypoglycemic agents that have also been shown to improve immune mechanisms associated with viral protection.

The outbreak of monkeypox: A clinical overview.

The development of new zoonotic diseases such as coronavirus disease 2019 (COVID-19) and monkeypox that can cause epidemics and high mortality rates have significantly threatened global health security. However, the increasing number of people with no immunity to poxvirus because of the end of the smallpox vaccination programme has created a vulnerable population for the monkeypox outbreak. On 23 July 2022, it was announced that the World Health Organization's director-general has determined that the multicountry outbreak of monkeypox constitutes a Public Health Emergency of International Concern. The monkeypox virus is an orthopoxvirus that causes a disease with symptoms similar to smallpox but less severe. Many unanswered questions remain regarding monkeypox's pathogenesis, transmission and host reservoir. There is currently no evidence that transmission by individuals can sustain zoonotic infections during human-to-human transmissions; the continued emergence of these pathogens highlights the interconnectedness of animals and humans. The increasing number of monkeypox cases outside the endemic region has highlighted the need for effective global capacity building to prevent the spread of the disease and its impact on global health security. The priority now is to stop the spread of the disease and protect frontline healthcare workers and the most vulnerable individuals. This article aims to comprehensively analyse the various aspects of the transmission and epidemiology of monkeypox. It also explores possible diagnostic techniques, therapeutics and prevention strategies. A key recommendation is that primary care and public health professionals are expected to increase their efforts to be vigilant and contain any potential outbreaks.

Making trouble.

The United States is moving to tighten oversight of studies that could make viruses more dangerous. But how far should it go?

Monkeypox viral infection and disease: A challenge for the allergist-immunologist.

Background: Human monkeypox is a zoonosis caused by the monkeypox virus, an orthopoxvirus and close relative of variola virus, the causative agent of smallpox. The disease was first reported in central Africa in 1970, where it continues to be endemic and has historically affected some of the poorest and most marginalized communities in the world. The condition has recently attracted global attention due to >14,000 cases, including five deaths, reported by the World Health Organization, and a total of 5189 confirmed monkeypox cases in the United States reported by the Centers for Disease Control and Prevention as of July 29, 2022. On July 23, 2022, the World Health Organization declared the current monkeypox outbreak a Public Health Emergency of International Concern. Objective: The purpose of the present report was to review the epidemiology of monkeypox viral infection; its clinical manifestations; and current recommendations for diagnosis, treatment, and use of vaccines for prevention of the disease, with a focus on those aspects that have particular relevance to the allergist/immunologist. Results: Monkeypox was discovered in the early 1970s and, for years, has been well described by researchers in west and central Africa, where the disease has been present for decades. Although this outbreak thus far has mostly affected men who have sex with men, it is possible that the disease could become endemic and could begin spreading in settings where there is close physical contact, which is how the virus is transmitted. Conclusion: Monkeypox is a different viral infection from the coronavirus. Unlike the coronavirus, which is an extremely contagious respiratory pathogen, monkeypox is primarily transmitted through body fluids and/or prolonged skin-to-skin contact. Although the control of monkeypox will require renewed efforts and resources, we have learned much from the past and have the tools to stop this virus from becoming yet another serious illness with which Americans have to contend. The allergist/immunologist can play a significant role.

Monkeypox: epidemiology, pathogenesis, treatment and prevention.

Monkeypox is a zoonotic disease that was once endemic in west and central Africa caused by monkeypox virus. However, cases recently have been confirmed in many nonendemic countries outside of Africa. WHO declared the ongoing monkeypox outbreak to be a public health emergency of international concern on July 23, 2022, in the context of the COVID-19 pandemic. The rapidly increasing number of confirmed cases could pose a threat to the international community. Here, we review the epidemiology of monkeypox, monkeypox virus reservoirs, novel transmission patterns, mutations and mechanisms of viral infection, clinical characteristics, laboratory diagnosis and treatment measures. In addition, strategies for the prevention, such as vaccination of smallpox vaccine, is also included. Current epidemiological data indicate that high frequency of human-to-human transmission could lead to further outbreaks, especially among men who have sex with men. The development of antiviral drugs and vaccines against monkeypox virus is urgently needed, despite some therapeutic effects of currently used drugs in the clinic. We provide useful information to improve the understanding of monkeypox virus and give guidance for the government and relative agency to prevent and control the further spread of monkeypox virus.

Monkeypox: what do dental professionals need to know?

Infection control is critical for the safe delivery of dental care. Infection control practices must be responsive to emerging and re-emerging infectious diseases and outbreaks, as was clearly seen during the peak of the COVID-19 pandemic. An emerging global outbreak of the monkeypox virus has again raised potential challenges for infection control in dentistry. Monkeypox is an infectious disease, characterised by a rash affecting the skin and soft tissues, including the oral cavity. Previously, cases were mostly seen following contact with infected animals in Central and West Africa, with limited human-to-human transmission within and outside of these areas. However, since May 2022, sustained human-to-human transmission has occurred globally. Monkeypox can be transmitted via close contact with an infected person, contaminated objects and surfaces, or by droplets and possibly aerosols, which is therefore of potential importance to dental settings. This article discusses the relevance of monkeypox to dental professionals, the typical presentation of the disease, its potential impact on infection prevention and control practices and the delivery of dental services. The current monkeypox outbreak highlights the need for a more sustained programme of research into dental infection control that can provide a solid evidence base to underpin preparedness planning for future outbreaks and pandemics.

Reemergence of monkeypox: prevention and management.

INTRODUCTION: The reemergence of monkeypox virus in the twenty-first century, calls for an urgency in its control and preventive measures. There is a long-standing concern that the reemergence of monkeypox across countries could lead to another epidemic like the COVID-19 pandemic. Understanding the disease ecology, preventing its transmission could help curbing its spread. The established treatment protocols along with development of new antiviral agents and vaccines could play a pivotal role in controlling its transmission. AREAS COVERED: In this review, we summarize the different modes of transmission of this disease, the associated symptoms, the standard protocol of treatment, the available vaccines and use of alternative treatments. We have collated recent research on novel entities that could potentially treat monkeypox infection. EXPERT OPINION: The One Health approach fostered by the World Health Organization (WHO) for emergent and reemerging zoonotic diseases has to be implemented with a view to curb their transmission. The growing global population and increased inter-country travel has led to rapid spread of transmissible pathogens. Stigmatization, associated with lack of knowledge can be prevented by enhancing awareness campaigns. Vaccines need to be administered to high-risk individuals, and drug discovery efforts need to be intensified to combat such diseases.

Prevention of monkeypox with vaccines: a rapid review.

The largest outbreak of monkeypox in history began in May, 2022, and has rapidly spread across the globe ever since. The purpose of this Review is to briefly describe human immune responses to orthopoxviruses; provide an overview of the vaccines available to combat this outbreak; and discuss the various clinical data and animal studies evaluating protective immunity to monkeypox elicited by vaccinia virus-based smallpox vaccines, address ongoing concerns regarding the outbreak, and provide suggestions for the appropriate use of vaccines as an outbreak control measure. Data showing clinical effectiveness (~85%) of smallpox vaccines against monkeypox come from surveillance studies conducted in central Africa in the 1980s and later during outbreaks in the same area. These data are supported by a large number of animal studies (primarily in non-human primates) with live virus challenge by various inoculation routes. These studies uniformly showed a high degree of protection and immunity against monkeypox virus following vaccination with various smallpox vaccines. Smallpox vaccines represent an effective countermeasure that can be used to control monkeypox outbreaks. However, smallpox vaccines do cause side-effects and the replication-competent, second-generation vaccines have contraindications. Third-generation vaccines, although safer for use in immunocompromised populations, require two doses, which is an impediment to rapid outbreak response. Lessons learned from the COVID-19 pandemic should be used to inform our collective response to this monkeypox outbreak and to future outbreaks.

Monkeypox emergency: Urgent questions and perspectives.

Amidst the COVID-19 pandemic, we now face another public health emergency in the form of monkeypox virus. As of August 1, the Centers for Disease Control and Prevention report over 23,000 cases in 80 countries. An inclusive and global collaborative effort to understand the biology, evolution, and spread of the virus as well as commitment to vaccine equity will be critical toward containing this outbreak. We share the voices of leading experts in this space on what they see as the most pressing questions and directions for the community.

Monkeypox Vaccination in the Republic of Korea: Identifying the High-Risk Target Group.

In June 2022, the first monkeypox case was reported as imported into Korea. The general public asked whether they should get vaccinated against monkeypox because of the recent COVID-19 vaccination experience. As of the current monkeypox outbreak situation, a ring vaccination strategy for the high-risk group is more appropriate than the mass population vaccination with smallpox vaccines. Therefore, identifying the proper target group by available vaccines based on the risk and benefit analysis is a key issue of the vaccination program. In addition, the target group should be reviewed by the epidemiological situation of the jurisdiction along with the updated evidence of the monkeypox virus on transmission dynamics, severity, and fatality.
