Understanding Monkeypox and its Impact
Monkeypox is a viral zoonosis caused by the monkeypox virus, a member of the Orthopoxvirus genus in the family Poxviridae. This virus shares similarities with the variola virus, which causes smallpox, although monkeypox is generally less severe.
The primary reservoir for the monkeypox virus is thought to be small mammals, such as rodents and squirrels, with humans contracting the virus through direct contact with the blood, bodily fluids, or cutaneous/lesional materials of infected animals.
Human-to-human transmission can also occur via respiratory droplets during prolonged face-to-face contact, direct contact with bodily fluids, or contaminated objects.
Initial symptoms of monkeypox typically appear about one to two weeks after exposure and include fever, intense headache, swelling of the lymph nodes, back pain, muscle aches, and a profound lack of energy.
A distinctive feature of monkeypox, which distinguishes it from other poxvirus infections, is its progression through several stages, starting with macules, papules, vesicles, and finally pustules, before forming crusts and scabs that eventually fall off. These symptomatic expressions often contribute to significant discomfort and concern among patients.
Historically, the impact of monkeypox on public health has been geographically confined primarily to Central and West Africa. However, recent sporadic outbreaks outside Africa underscore a growing concern for global health security.
The increasing frequency of human cases is attributed to various factors, including declining immunity in the population due to the cessation of smallpox vaccination programs and increased human-animal interactions.
