Monkeypox is an uncommon disease caused by a monkeypox virus infection and is a member of the Orthopoxvirus genus in the Poxviridae family.
According to Athen Virtual Clinic, the orthopoxvirus genus also include variola virus (which causes smallpox), vaccinia virus (used in smallpox vaccine), and cowpox virus. Monkeypox is mainly spread by wild animals in parts of west or central Africa.
Monkeypox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was reported in 1970 in the Democratic Republic of the Congo (DRC), and since then the infection has been reported in a number of central and western African countries. Most cases are reported from the DRC and Nigeria.
More than 80 cases have been confirmed in Europe, the US, Canada, Australia and Israel.
The virus is transmitted from one person to another by close contact with lesions, body fluids, respiratory droplets and contaminated materials such as bedding. The incubation period of monkeypox is usually from 6 to 13 days but can range from 5 to 21 days.
Its symptoms in people are similar to, but less severe than, smallpox symptoms. Fever, headache, muscle aches, and tiredness are among symptoms of monkeypox.
The fundamental distinction between smallpox and monkeypox symptoms is that monkeypox causes lymph node swelling (lymphadenopathy), but smallpox does not.
The illness begins with:
Fever
Headache
Muscle aches
Backache
Swollen lymph nodes
Chills
Exhaustion
The patient develops a rash 1 to 3 days (sometimes longer) following the onset of fever, which usually starts on the face and spreads to other regions of the body.
Stages before falling off: Macules, papules, vesicles, pustules and scabs.
The disease lasts about 24 weeks on average. Monkeypox has been demonstrated to kill one out of every ten people who develop the disease in Africa.
The World Health Organization has so far warned that the world is facing “formidable” challenges of monkeypox.
Tedros Adhanom Ghebreyesus was speaking in Geneva, where the UN health agency’s experts were discussing the monkeypox outbreak in 15 nations outside Africa. More than 80 cases have been confirmed in Europe, the US, Canada, Australia and Israel.
Speaking at Sunday’s opening of his agency’s World Health Assembly, Tedros said: “Of course the [Covid] pandemic is not the only crisis in our world.”
“As we speak, our colleagues around the world are responding to outbreaks of Ebola in the Democratic Republic of Congo, monkeypox and hepatitis of unknown cause and complex humanitarian crises in Afghanistan, Ethiopia, Somalia, South Sudan, the Syrian Arab Republic, Ukraine and Yemen.”
“We face a formidable convergence of disease, drought, famine and war, fuelled by climate change, inequity and geopolitical rivalry,” the WHO head added.
She said the virus was now spreading in the community, with cases detected which have had no contact with anyone who has visited West Africa, where the disease is endemic. But the risk to the general population remains “extremely low”, with cases so far mostly found in some urban areas and among gay or bisexual men, Hopkins said.
Although there is no specific vaccine for monkeypox, several countries have said they are stocking smallpox vaccines, which are about 85 per cent effective in preventing infection as the two viruses are quite similar.
It is not yet clear why this unexpected outbreak is happening now. One possibility is that the virus has changed in some way, although currently there is little evidence to suggest this is a new variant. Another explanation is that the virus has found itself in the right place at the right time to thrive.
