First reported	2022

The 2022–2023 mpox outbreak in South America refers to the spread of the Monkeypox virus in various countries across the South American continent. This outbreak is part of the larger 2022–2023 mpox outbreak that has affected multiple regions worldwide.

Background

Mpox, also known as monkeypox, is a viral zoonotic disease caused by the Monkeypox virus, a member of the Orthopoxvirus genus. The disease is characterized by symptoms similar to those of smallpox, though generally less severe. The virus is endemic to certain regions in Central Africa and West Africa, but recent outbreaks have been reported in non-endemic areas, including South America.

Epidemiology

The outbreak in South America began in 2022, with the first cases reported in Brazil. The virus spread to other countries in the region, including Argentina, Chile, Colombia, and Peru. The transmission of the virus in these areas has been attributed to human-to-human contact, particularly in densely populated urban centers.

Transmission

The Monkeypox virus is transmitted through close contact with infected individuals or animals. Human-to-human transmission occurs via respiratory droplets, direct contact with bodily fluids, or contact with contaminated materials such as bedding. The outbreak in South America has highlighted the role of international travel and trade in the spread of the virus.

Clinical Features

The clinical presentation of mpox includes fever, headache, muscle aches, and a characteristic rash that progresses through several stages before crusting and falling off. The incubation period is typically 7-14 days, but can range from 5-21 days.

Public Health Response

Countries in South America have implemented various public health measures to control the outbreak. These include:

• Surveillance and contact tracing to identify and isolate cases.
• Public awareness campaigns to educate the population about the symptoms and transmission of mpox.
• Vaccination campaigns targeting high-risk populations.

Impact

The outbreak has had significant public health implications, straining healthcare systems and prompting international collaboration to contain the virus. The economic impact has also been notable, affecting travel and trade in the region.

Research and Development

Efforts are underway to develop and distribute vaccines and antiviral treatments for mpox. The World Health Organization and other international bodies are coordinating research initiatives to better understand the virus and its transmission dynamics.
