29 May, 2022|Abuja - Public Health Advisory on Monkeypox
Monkeypox (MPX) is a rare viral zoonotic infectious disease (i.e., an infection transmitted from animals to humans) that is endemic in areas in and near tropical rainforests in Central and West Africa. It is caused by the Monkeypox virus which belongs to the same Orthopoxvirus genus and Poxviridae family of viruses as the Variola virus (Smallpox virus), the Vaccinia virus (used in smallpox vaccine for eradication programme), and the cowpox virus (used in earlier generations of smallpox vaccines) and some other viruses. There are two types (clades) of the MPX virus: the West African and the Central African clade. Available data suggests human disease with the Central African clade is more severe than with the West African clade
The exact reservoir of the MPX virus is still unknown although rodents are suspected to play a part in transmission. So far, the virus itself has been identified in wild animals in Africa only twice (from a type of squirrel and a type of monkey in the Democratic Republic of Congo and Cote d’Ivoire respectively). Rodents from West Africa (rats, dormice, and squirrels) being sold in a store in the United States contributed to a 2003 outbreak.
The virus can spread both from animal-to-human (which is the first (spill-over) event preceding the detection of cases in humans), and from human-to-human. Animal-to-human transmission may occur by direct contact with the blood, body fluids, the skin or mucosal lesions of infected animals (e.g., monkeys, squirrels, and rodents). This can happen through a bite, scratch, handling of, or eating inadequately cooked or other products of infected bushmeat. Human-to-human (person-to-person) transmission occurs when a person comes into contact with the virus from an infected human, or materials contaminated with the virus such as clothing, beddings. ...
