Seven more cases of monkeypox have been reported in the UK today, as the tropical virus is often found in Africa alone and continues to sweep the world.
The new infections, all detected in England, bring Britain’s total to 78 since the first case of the ongoing outbreak was made public on 7 May. To date, Scotland has reported a case of smallpox in the monkey, while no infection has been reported in Wales or Northern Ireland.
Officials claimed that there was a “remarkable proportion” between gay and bisexual men, but did not provide an exact breakdown. No gender or age details have been shared.
Nineteen countries around the world, mostly in Europe, have now detected the smallpox-like virus over the past three weeks.
Infections are only sporadically detected outside of West and Central Africa, where the virus is endemic in animals. Imported outbreaks have always faded naturally after a few cases.
The UKHSA’s chief medical adviser, Dr Susan Hopkins, said new cases of monkeypox were being detected “quickly” due to “extensive surveillance and contact monitoring networks”.
It comes when scientists warned today that the elimination of the smallpox vaccination scheme four decades ago, when the virus was eradicated, has led to a decline in immunity that has made the British more vulnerable to smallpox. .
Although not purposely designed for monkeypox, the Bavarian Nordic-based Imvanex jab, based in Denmark, is up to 85% effective because the two viruses are very similar.
The smallpox vaccine, called Imvanex in the UK and Jynneos in the US, can protect against monkeypox because the viruses that cause the disease are related.
Professor Neil Mabbott (pictured), a professor of immunopathology at the University of Edinburgh, told MailOnline that this has made those under 50 more susceptible to the virus than those over 50 who have been attacked.
Professor Paul Hunter (pictured), an infectious disease expert based at the University of East Anglia, said it was “hard to say”. He noted data showing that the smallpox vaccine was only fully effective for “about five years.”
In the UK, high-risk contacts of confirmed cases are offered Imvanex vaccine. This strategy, known as ring vaccination, involves puncturing and controlling anyone around an infected person to form a buffer of immune people to limit the spread of the disease.
The disease, first discovered in laboratory monkeys in the late 1950s, is usually mild, but can cause serious illness in some cases. It can kill up to 10% of people it infects.
The softer strain caused by the current outbreak kills one in 100, similar to when it first hit Covid.
The monkeypox has an incubation period of up to 21 days, which means that it can take three weeks for symptoms to appear.
Symptoms include fever, headache, muscle aches, back pain, swollen lymph nodes, chills, and exhaustion.
A rash can develop, often starting on the face, which then spreads to other parts of the body, including the genitals. The rash may look like chickenpox or syphilis, and crusts may form and then fall off.
Dr Hopkins said: “We continue to rapidly detect new cases of monkeypox through our extensive surveillance network and NHS services.
“If someone suspects that they may have rashes or injuries on any part of their body, especially if they have recently had a new sexual relationship, they should limit their contact with other people and contact NHS 111 or the local sexual health service. as soon as possible”. but please call before attending in person.
UKHSA teams are contacting high-risk contacts for confirmed cases and advising them to isolate themselves at home for three weeks and avoid contact with children.
They are also offered the Imvanex vaccine to form a buffer of immune people around a confirmed case to limit the spread of the disease. The strategy, known as ring vaccination, has been used in previous monkeypox outbreaks and is also being carried out in some EU countries.
At least 236 cases of monkeypox have been confirmed worldwide since the first patient became ill in the UK on May 6, with the majority of infections between gay and bisexual men.
The United Arab Emirates, the Czech Republic and Slovenia are the last countries to register infections.
Pavel Dlouhy, head of the Society for Infectious Diseases of the Czech Republic, said: “It was only a matter of time, we have been waiting for it for days.”
The Czech man showed symptoms of the disease after returning from a festival in Antwerp, Belgium, in early May. Since then, several cases of monkeypox have been linked to Darklands, a large-scale fetish festival held from May 5-8.
In Slovenia, it has also been confirmed that a man who developed symptoms after returning from the Canary Islands had smallpox, according to health authorities. Monkeypox infections have already been linked to the festival of gay pride in Gran Canaria, which was attended by up to 80,000 people between 5 and 15 May.
The UAE announced its first case of smallpox in a 29-year-old woman visiting the Gulf country from West Africa.
It comes when experts warned today that the end of the routine smallpox vaccine has left the world more vulnerable to monkeypox outbreaks.
The UK smallpox vaccination campaign ended in 1971, when the disease was essentially eradicated.
In Britain, babies under the age of 12 months received jab, with a recommended booster dose for children and adults in school.
It means that 51-year-olds in the UK are now the youngest cohort that could be vaccinated against smallpox and smallpox in monkeys.
As the proportion of the UK population with monkeypox immunity has decreased, it has theoretically given room for the virus to circulate and transmit more easily.
Dr Romulus Breban, a researcher at the Institut Pasteur in Paris, said the current global outbreak was “waiting to happen” due to the “almost zero” level of immunity in the world.
He told the Guardian, “Our level of immunity is almost zero. People 50 and older are likely to be immune, but the rest of us aren’t, so we’re very, very susceptible.”
In an article published in the World Health Organization’s Bulletin in September 2020, Dr. Breban and colleagues warned that smallpox was “an emerging infectious disease for which the frequency of outbreaks and the expected size of outbreaks in human populations have steadily increased. “
The team identified the spread of cases beyond West and Central Africa as a pattern fueled by declining immunity to orthopox viruses, a family of viruses that also includes smallpox and monkeypox. , due to the end of the vaccination scheme.
Professor Neil Mabbott, an immunopathologist at the University of Edinburgh, told MailOnline that those over 50 are the only group protected from monkeypox. “While the level of immunity will decrease over time, smallpox vaccination provides lasting protection,” he said. “Some estimates suggest that this may take decades.”
He said: “The smallpox virus is closely related to smallpox. So smallpox vaccines are very effective against smallpox. Here is some evidence that smallpox vaccines used decades ago are still effective. against smallpox.
“Most people under the age of 50 are unlikely to have received a smallpox vaccine in the past. This part of the population will have no vaccine-induced smallpox immunity or smallpox cross-protection.
“As a result, they will be more susceptible to the smallpox virus than those who have been vaccinated.”
However, not all experts agree that a drop in immunity is fueling the spread of monkeypox.
Professor Paul Hunter, an infectious disease expert at the University of East Anglia, said it was “hard to say”.
Health officials have warned that smallpox, a virus endemic to parts of Africa and known for its rare and unusual rashes, bumps and injuries, could also spread to some pets and become endemic in Europe. Undated archive image issued by the UK Health Security Agency on the stages of Monkeypox
The smallpox outbreak could have been caused by sex in two radishes in Belgium and Spain, warns a WHO expert
Sexual transmission at two festivals in Europe may have caused the monkeypox outbreak to escalate in the world, according to a World Health Organization expert.
Dr. David Heymann, who used to head the WHO emergency department, revealed that it was the main theory behind the origins of the current group of cases.
He said: “We know that monkeypox can spread when there is close contact with the lesions of an infected person, and it seems that sexual contact has now amplified this transmission.
“It is very possible that someone has become infected, has developed injuries to their genitals, hands or elsewhere, and then spread to other people when there was close physical or sexual contact.
“And then there were those international events that spread the word around the world, in the US and other European countries.”
Despite not naming any festival, the health officials in charge of containing the virus have already begun to trace the cases to the festival of gay pride in Gran Canaria, which was attended by up to 80,000 people between 5 and 15 May .
Meanwhile, three cases have been linked in Belgium to Darklands, a large-scale fetish festival in Antwerp, held from 5 to 8 May. Since then, organizers have said there are “reasons to assume” that someone at the event was infected.
Spanish health officials have also linked many cases to a single ‘sauna’ in Madrid.
He noted data showing that the smallpox vaccine was only fully effective for “about five years.”
He told MailOnline: “I think it would be a push to take over [it gives] important protection 50 years later. There may still be some modifying effects, but I don’t know. “
Scientists do not know the origin of smallpox.
But findings of smallpox-like eruptions in Egyptian mummies suggest that the virus has existed for at least 3,000 years.
At its peak, it was estimated that 50 million cases occurred each year.
The virus, which killed one percent of people it infected, was last detected in Somalia in 1977 and the World Health Organization said …
