The outbreak of monkeypox in Britain has doubled in size, health officials will announce today.
Britain is stockpiling thousands of vaccines and treatments against monkeypox amid fears that the current flow of cases is just the tip of the iceberg.
So far, nine Britons have been diagnosed with the contagious virus, but another 11 are expected to be confirmed today, The Times reported.
The majority of cases are unrelated, suggesting that they are more widespread, although ministers are considering a public health campaign to warn gays that this may be more common to them.
Although smallpox is not classified as a sexually transmitted disease, many recent cases in the UK have been in men who have sex with other men.
The UK Drug Monitoring Service told MailOnline that it was monitoring the current epidemic and “working with companies to quickly provide appropriate treatments”.
Health chiefs also told MailOnline that they had bought thousands of doses of vaccines and were already using them for close contact with infected Britons.
Eleven more cases of monkeypox are expected to be announced today, doubling the size of the outbreak in the UK
Monkeypox is a rare viral infection that kills up to one in ten of those infected, but does not spread easily among humans. Tropical disease is endemic in parts of Africa and is known for its rare and unusual rashes, bumps and lesions (photo file)
Nurses and doctors are advised to be “vigilant” for patients who have a new rash or scabies lesion (as above)
Antiviral drugs and injections designed to target smallpox have cross-protection against monkeypox, and the two viruses are genetically very similar.
The latter outbreak has been described as “unusual” by experts, as human-to-human transmission of monkeypox is thought to be extremely rare.
Six of the cases in the UK involve gays or bisexual men, which officials say “strongly suggests a spread on sexual networks”.
Dr Susan Hopkins, chief medical adviser to the UK Health Security Agency, called on gay and bisexual men to check for irregular rashes and talk to a sexual health doctor, if any.
Cases have also been reported in the United States, Spain and Portugal, making it the most common outbreak of monkeypox to date. Canada also has suspicious cases.

There are several antiviral drugs and therapies for smallpox that appear to work in monkeypox, including the drug tecovirimat, which was approved for monkeypox in the EU in January.
Smallpox can kill up to one in ten people who get sick, but the new cases have the West African variant, which is deadly for about one in 100.
Initial symptoms include fever, headache, muscle aches, back pain, swollen lymph nodes, chills and exhaustion.
A rash can develop, often starting in the face and then spreading to other parts of the body, including the genitals.
The rash changes and goes through various stages and can look like chickenpox or syphilis before finally forming scabs that later disappear.
A vaccine known as Imvanex was approved in 2013 in the United Kingdom for the treatment of smallpox, but studies have since shown that it is 85% effective in preventing monkeypox.
It is not approved for monkeypox in the United Kingdom, but health professionals can use it “off-label”.
Imvanex is now available for close contact with positive cases and physicians treating cases “based on their risk factor”.
The monkeypox has an incubation period of up to 21 days, so the positive cases and their contacts are isolated for three weeks.

HOW IS THE MONKEY STORK TREATED?
No specific drugs or vaccines have been developed for monkeypox, which has so far been rare in cases outside Africa.
But antivirals and injections designed to target smallpox have cross-protection against monkeypox, as the two viruses are genetically very similar.

A vaccine known as Imvanex was approved in 2013 in the United Kingdom for the treatment of smallpox, but studies have since shown that it is 85% effective in preventing monkeypox.
It is not approved for monkeypox in the United Kingdom, but health professionals can use it “off-label”.
Imvanex is now available for close contact with positive cases and physicians treating cases “based on their risk factor”.
Imvanex contains a modified form of the vaccinia virus, which is similar to the family of viruses that cause smallpox and smallpox, but do not cause disease in humans.
Due to their similarity to measles viruses, antibodies produced against this virus offer cross-protection.
Antivirals
There are several antivirals and therapies for smallpox and other diseases that appear to work in monkeypox.
Tecovirimat was approved for monkeypox in the EU in January and is given in pill form.
Tecovirimat prevents the virus from leaving an infected cell by preventing the virus from spreading in the body.
An injectable antiviral drug used to treat AIDS, called cidofovir, can be used to control the infection, according to the US Centers for Disease Control and Prevention (CDC). It also works by stopping the growth of the virus.
Antibody therapy
Therapy that uses blood collected from people who have been vaccinated with the smallpox vaccine can also be used to treat monkeypox.
Known as vaccine immunoglobulin (VIG), it is designed to treat people with severe smallpox who cannot be vaccinated on their own.
It works by injecting antibodies from a vaccinated person into an unvaccinated person, hoping to elicit a similar immune response.
A spokesman for the Ministry of Health said: “We have taken active steps to prepare for further cases of monkeypox in the UK and have provided thousands of doses of vaccines that are effective against monkeypox, which are used to protect key health professionals. and at-risk persons who may have been exposed. ‘
Imvanex jab has been used to treat close contact with cases of monkeypox since 2018, when a small number of cases with links to travel to Africa were discovered.
Imvanex contains a modified form of the vaccinia virus, which is similar to the family of viruses that cause smallpox and smallpox, but do not cause disease in humans.
Due to their similarity to measles viruses, antibodies produced against this virus offer cross-protection.

A spokesman for the Medicines and Health Regulatory Authority (MHRA) told MailOnline: “There is no approved vaccine or medicine for monkeypox in the UK.”
But they added: “We are closely monitoring the situation and working with companies to quickly offer appropriate treatments for monkeypox.”
Professor Kevin Fenton, regional director of public health in London, said that if the outbreak in the capital continues to grow, then the introduction of vaccines and treatments could be extended to more groups.
He told BBC Radio 4’s Today program: “If we see more cases and it continues to spread, then there are plans to ensure that we have more anti-virus agents to deal with it.
“We are watching closely to see how this will spread over the next week or two, and then we will have a better idea of how to design and plan for next month.”
Six of the UK’s nine cases are based in London, two in the South East of England and one in the North East.
All but one of the patients in the United Kingdom – the first to arrive from Nigeria – appear to have been infected in the United Kingdom.
The United States has reported its first case of monkeypox at night in a man from Massachusetts who recently returned from Canada.
In Canada, at least thirteen probable cases are being investigated and tests are being performed to confirm the virus.
Seven people have been diagnosed in Spain and dozens more are being monitored and tested for the disease. Portugal has said at least five cases have been confirmed.
All men diagnosed in Spain are gay or bisexual, according to local media.
The World Health Organization (WHO) has warned that it expects more cases in more countries in the coming weeks.
Until now, cases of monkeypox have been limited to travelers and their relatives returning from West and Central Africa, where the virus is endemic.
But experts now fear it is spreading for the first time.
Dr Simon Clark, a microbiologist at the University of Reading, told MailOnline that he suspected that the number of cases in the UK was already “dozens”.
But he insisted the disease would not spread like Covid, adding: “I would be surprised if we ever get to more than 100 cases [in Britain]’.
Professor Bill Hanaj, a public health expert at Harvard University, said it was plausible that the show had been “unnoticed for some time.”
He tweeted: “Because people don’t expect to see monkeypox and that’s why they don’t diagnose it.
“You hear the beating of hooves, you expect horses, not unicorns. You see lesions, you don’t expect monkeypox, and you think it’s something else.
Experts believe that young people are most at risk of contracting or contracting the disease, as they are less likely to have been vaccinated against smallpox, which was eradicated in the 1980s.
They are still trying to develop its main route of transmission, but health experts investigating a new outbreak of monkeypox in Britain say the virus could be spread through sex.
So far, it has never been established that it is sexually transmitted.
But it was known that it could be transmitted through close contact with body fluids, respiratory droplets and lesions – which means that it is theoretically possible to be transmitted through sex.
