Monkeypox (Mpox) : Overview & Diagnosis

Monkeypox (Mpox) : Overview & Diagnosis

Monkeypox, also known as Mpox, is a viral disease that Primarily affects monkeys, rodents, and other wild animals. However, it can also be Transmitted to humans, causing a rare but Potentially serious illness. The Monkeypox virus, a member of the Poxviridae family, is responsible for the illness.

Monkeypox was first identified in 1958 when Outbreaks occurred in monkeys kept for research. The first human case was reported in 1970 in the Democratic Republic of Congo (formerly Zaire). Since then, Monkeypox Outbreaks have been reported Sporadically in several African countries, including Nigeria, Cameroon, and the Central African Republic.

Transmission of Monkeypox to humans can occur through direct contact with infected animals. Such as handling monkeys or rodents, or through close contact with infected humans. The virus can be Transmitted through Respiratory Droplets, bodily fluids, and Contaminated materials, such as bedding or clothing.

The symptoms of Monkeypox in humans are similar to those of Smallpox, although generally less severe. Fever, headache, Muscular pains, and Exhaustion are some of the early signs. A rash then appears after that, usually first on the face before Spreading to other regions of the body. The rash Progresses through different stages, including the Formation of Fluid-filled lesions that eventually crust over. 2 to 4 weeks are the typical length of the disease.

Currently, there is no specific treatment for Monkeypox. However, Supportive care, such as Managing symptoms and Preventing Secondary infections, can help with recovery. Vaccination against Smallpox, known as the Smallpox vaccine, has been shown to provide some protection against Monkeypox and is Recommended for people at high risk of Exposure. Such as Laboratory workers and Healthcare personnel.
