Mpox was first identified in 1958 during an outbreak among captive monkeys in Denmark.
The Origins of Mpox Discovery
Mpox, once known primarily as monkeypox, was first discovered in 1958. The initial identification occurred when two outbreaks of a pox-like disease affected colonies of monkeys kept for research in a laboratory in Copenhagen, Denmark. These monkeys were imported from Africa, which hinted at the virus’s geographic origin. Despite the name, monkeys are not the primary reservoir for the virus; rather, it is believed that certain rodents and small mammals native to Central and West Africa serve as the natural hosts.
The discovery of mpox came during a period when scientists were intensively studying poxviruses following the eradication of smallpox. Researchers noticed that this new virus caused symptoms similar to smallpox but with some distinct differences. The identification was significant because it added another member to the Orthopoxvirus genus, which includes variola virus (smallpox), vaccinia virus (used in vaccines), and cowpox virus.
When Was Mpox Discovered? Tracing Early Cases
Though mpox was first identified in laboratory monkeys in 1958, the first human case wasn’t documented until 1970. This case emerged in the Democratic Republic of Congo (formerly Zaire), marking mpox as a zoonotic disease capable of crossing from animals to humans. The patient was a nine-month-old child who presented with symptoms resembling smallpox but without prior smallpox vaccination.
The discovery of human cases raised alarms among health officials because smallpox had been declared eradicated just months earlier, in 1980. Mpox’s resemblance to smallpox made it difficult to diagnose initially, but molecular and serological tests eventually confirmed its unique identity.
In subsequent years, sporadic outbreaks occurred primarily in Central and West African countries such as Nigeria, Cameroon, and Gabon. These outbreaks often involved close contact with wild animals or infected humans and highlighted the ongoing risk posed by zoonotic viruses.
Geographic Spread and Epidemiology
Mpox has remained largely endemic to rainforest regions of Central and West Africa since its discovery. However, isolated cases have appeared outside Africa due to travel or importation of infected animals. For example, in 2003, an outbreak occurred in the United States linked to imported Gambian pouched rats that transmitted the virus to pet prairie dogs.
The epidemiology of mpox reveals two distinct genetic clades: the Central African (Congo Basin) clade and the West African clade. The Central African clade is generally associated with more severe disease and higher mortality rates compared to its West African counterpart.
Understanding Mpox Virus Characteristics
Mpox is caused by an orthopoxvirus closely related to variola virus but genetically distinct enough to be classified separately. It is a double-stranded DNA virus with a large genome encoding numerous proteins involved in viral replication and immune evasion.
Transmission occurs through direct contact with infected bodily fluids, respiratory droplets during prolonged face-to-face interaction, or contact with contaminated materials such as bedding or clothing. Animal-to-human transmission typically results from bites or scratches from infected animals or handling wild meat.
Symptoms usually begin with fever, headache, muscle aches, and exhaustion followed by a characteristic rash that progresses through several stages: macules, papules, vesicles, pustules, then scabs. Lymphadenopathy (swollen lymph nodes) is a hallmark symptom distinguishing mpox from smallpox.
Comparing Mpox With Other Poxviruses
The Orthopoxvirus genus includes several viruses relevant to human health:
| Virus | Primary Host | Human Impact |
|---|---|---|
| Variola Virus (Smallpox) | Humans only | Eradicated; caused deadly disease globally until 1980 |
| Mpox Virus | Rodents/Monkeys (Zoonotic) | Causes sporadic outbreaks; milder than smallpox but can be severe |
| Cowpox Virus | Cows/Wild rodents | Mild human infections; historically used for vaccination against smallpox |
While mpox shares many clinical features with smallpox—including fever and rash—the presence of swollen lymph nodes sets it apart clinically. Moreover, mpox has never reached pandemic levels like smallpox did but remains a public health concern due to its zoonotic nature and potential for outbreaks.
The Role of Surveillance After Mpox Discovery
Following the initial discovery of mpox both in monkeys (1958) and humans (1970), global health authorities ramped up surveillance efforts especially across endemic regions. Early detection became crucial because symptoms mimic those of other rash illnesses such as chickenpox or measles.
Surveillance programs focused on identifying animal reservoirs through trapping studies and serological testing while monitoring human cases through hospital records and community reporting systems. These efforts helped map transmission patterns and identify risk factors such as hunting bushmeat or living near forested areas.
International cooperation also increased after several outbreaks demonstrated cross-border spread potential. Organizations like the World Health Organization (WHO) issued guidelines on diagnosis, treatment protocols, isolation measures, and vaccination strategies using existing smallpox vaccines that showed cross-protection against mpox.
The Impact of Smallpox Eradication on Mpox Emergence
The eradication of smallpox in 1980 led to cessation of routine smallpox vaccinations worldwide. While this was an incredible public health success story saving millions of lives, it inadvertently created an immunological gap against related orthopoxviruses like mpox.
Before eradication programs ended vaccination campaigns, most people had some level of immunity protecting them against orthopoxviruses broadly. Afterward, younger generations without vaccination became more susceptible to infections like mpox once exposed.
This shift partly explains why cases began increasing decades after initial discovery—populations lost herd immunity benefits previously conferred by widespread vaccination against variola virus.
Treatment Options Since Mpox Discovery
Since its discovery over six decades ago, treatment options for mpox have evolved slowly but steadily. There is no specific antiviral approved exclusively for mpox; however, several drugs developed for other orthopoxviruses show promise:
- Tecovirimat: Originally developed for smallpox treatment; inhibits viral envelope formation preventing spread.
- Cidofovir: An antiviral used for cytomegalovirus infections that has shown activity against orthopoxviruses.
- Brincidofovir: A lipid conjugate prodrug related to cidofovir with improved safety profile.
Supportive care remains essential including hydration management, fever control, pain relief for lesions, and prevention of secondary bacterial infections.
Vaccination strategies also play a role post-discovery—vaccines based on vaccinia virus provide cross-protection against mpox infection. Newer vaccines like JYNNEOS have been licensed specifically targeting both smallpox and monkeypox viruses offering safer immunization options especially during outbreaks.
The Importance of Public Awareness Since Discovery
Public education about mpox has been critical since its discovery because awareness can reduce transmission risks significantly. Understanding modes of transmission—such as avoiding contact with wild animals or infected individuals—and recognizing early symptoms helps communities seek timely medical attention.
Health campaigns target high-risk groups including hunters or people living near animal reservoirs emphasizing protective measures like wearing gloves when handling bushmeat or isolating suspected cases promptly.
Moreover, combating misinformation about mpox remains vital since confusion between it and other diseases can delay diagnosis or lead to stigmatization affecting outbreak control efforts adversely.
