Public health officials confirm first case of Monkeypox identified in Wales
The first case of monkeypox has been identified in Wales, public health officials have said.
Cases of Monkeypox – which is usually found in west and central Africa – have been on the increase during the past month with more than 200 confirmed cases recorded in Britain, Portugal, Spain and the United States.
To protect patient confidentiality, no further details have been released about the case in Wales.
It does not usually spread easily between people and the overall risk to the public is low.
It is a mild self-limiting illness which causes fever symptoms as well as a distinctive bumpy rash, most people recover within a few weeks.
Most cases in the current outbreak have been in youngish men, but the virus can spread to anyone.
Public Health Wales has said that everyone should aware of the monkeypox symptoms, “but it is important that gay and bisexual men are alert as it’s believed to be spreading in sexual networks.”
Dr Giri Shankar, director of health protection for Public Health Wales, said: “Public Health Wales is today confirming that a case of monkeypox has been identified in Wales.
“We are working with the UK Health Security Agency (UKHSA), Public Health Scotland, and Public Health Agency Northern Ireland, and we are ready to respond to cases of monkeypox in Wales.
“The case is being managed appropriately. To protect patient confidentiality, no further details relating to the patient will be disclosed.
“We are reassuring people that monkeypox does not usually spread easily between people, and the overall risk to the general public is low. It is usually a mild self-limiting illness, and most people recover within a few weeks. However, severe illness can occur in some individuals.
“Initial symptoms of monkeypox include fever, headache, muscle aches, backache, swollen lymph nodes, chills and exhaustion. A rash can develop, often beginning on the face, then spreading to other parts of the body, particularly the hands and feet. The rash changes and goes through different stages before finally forming a scab, which later falls off.
“Everyone is being asked to be aware of the monkeypox symptoms, but it is important that gay and bisexual men are alert as it’s believed to be spreading in sexual networks.
“Anyone with unusual rashes or lesions on any part of their body should contact NHS 111 or call a sexual health service if they have concerns.”
How is monkeypox spreading?
The first patient in the current outbreak had returned to the UK from travels to Nigeria where monkeypox is endemic. However, cases are now spreading among people who have not travelled to west or central Africa, suggesting local transmission is occurring.
Monkeypox usually spreads by close contact and respiratory droplets. However, sexual transmission (via semen and/or vaginal fluid) has been posited as an additional possible route. The World Health Organization (WHO) says: “Studies are needed to better understand this risk.”
Most cases in the current outbreak have been in youngish men, but the virus can spread to anyone.
What are the symptoms?
Early symptoms are flu-like, such as a fever, headaches, aching muscles and swollen lymph nodes.
Once the fever breaks, a rash can develop, often beginning on the face and then spreading to other parts of the body – most commonly the palms of the hands and soles of the feet.
How deadly is monkeypox?
Monkeypox is mostly a mild, self-limiting disease lasting two-to-three weeks. However, in some cases, it can cause death. According to the WHO, the fatality rate “in recent times” has been around 3% to 6%. The west African monkeypox virus is considered to be milder than the central African one.
Monkeypox tends to cause more serious disease in people who are immunocompromised – such as those undergoing chemotherapy – and children. There have been no deaths from monkeypox in the current worldwide outbreak, but, according to the Daily Telegraph, one child in the UK is in intensive care with the disease.
Why is it called monkeypox?
Monkeypox was first identified in laboratory monkeys (macaques) in Denmark in 1958, hence the name. However, monkeys don’t seem to be the natural hosts of the virus. It is more commonly found in rats, mice and squirrels. The first case in humans was seen in the 1970s in the Democratic Republic of the Congo.
Is monkeypox related to smallpox and chickenpox?
Monkeypox is related to smallpox – they are both orthopoxviruses – but it is not related to chickenpox. Despite the name, chickenpox is a herpes virus, not a poxvirus. (How “chicken” got in the name is not entirely clear. In his dictionary of 1755, Samuel Johnson surmised that it is so named because it is “of no very great danger”.) Nevertheless, the vesicles (little pus-filled blisters) caused by monkeypox are similar in appearance to those of chickenpox.
Are cases likely to continue rising?
Cases are likely to continue to rise significantly over the next two-to-three weeks, but this is not another pandemic in the making. Monkeypox doesn’t spread anywhere near as easily as the airborne virus SARS-CoV-2 that causes COVID-19.
Has monkeypox evolved to be more virulent?
RNA viruses, such as SARS-CoV-2, don’t have the ability to check their genetic code for mistakes each time they replicate, so they tend to evolve faster. Monkeypox is a DNA virus, which does have the ability to check itself for genetic mistakes each time it replicates, so it tends to mutate a lot slower.
The first genome sequence of the current outbreak (from a patient in Portugal) suggests that the virus is very similar to the monkeypox strain that was circulating in 2018 and 2019 in the UK, Singapore and Israel. So it is unlikely that the current outbreak is the result of a mutated virus that is better at spreading.
How is monkeypox diagnosed?
In the UK, swab samples taken from the patient are sent to a specialist laboratory that handles rare pathogens, where a PCR test is run to confirm monkeypox. The UK Health Security Agency has only one rare and imported pathogens laboratory.
Is there a vaccine for it?
Vaccines for smallpox, which contain the lab-made vaccinia virus, can protect against monkeypox. However, the vaccine that was used to eradicate smallpox can have severe side-effects, killing around one in a million people vaccinated.
The only vaccine specifically approved for monkeypox, Imvanex, is made by a company called Bavarian Nordic. It uses a nonreplicating form of vaccinia, which causes fewer side-effects. It was approved by the US Food and Drug Administration and the European Medicines Agency in 2019 – but only for use in people 18 years of age or older.
UK health secretary Sajid Javid said that the UK government will be stocking up on vaccines that are effective against monkeypox. The UK currently has about 5,000 doses of smallpox vaccine, which has an efficacy of around 85% against monkeypox.
Are there drugs to treat it?
There are no specific drugs to treat monkeypox. However, antivirals such as cidofovir and brincidofovir have been proven to be effective against poxviruses in animals and may also be effective against monkeypox infections in humans.
