Adults who have been vaccinated against smallpox may have been vaccinated, say researchers. Healthy children and adults are often less ill.
In a world tired of fighting coronavirus, the outbreak of monologue raises an important question: Am I in danger?
The answer is reassuring. Most children and adults with healthy immune systems are more likely to avoid serious illness, experts say in an interview. But there are two groups at high risk.
One includes children under six months of age. But they have not been affected by the current outbreak. And many older people, a group that is more likely to be infected with the monopoly virus, are at least protected from smallpox vaccines for decades, research suggests.
Vaccinated adults may become infected but may only survive with mild symptoms.
“The key point is that even those who were vaccinated for decades before maintaining a high level of immunity and immunity,” said Dr. Luigi Ferrucci, scientific director of the National Institute on Aging.
“Even if they were vaccinated 50 years ago, that protection must be there,” he said.
In the United States, the common smallpox vaccine ended in 1972. The military continued its immunization program until 1991 as a precautionary measure against bioterrorism attacks.
Questions about the effectiveness of smallpox vaccine increased after the anthrax outbreak in 2001, said Dr. Anthony S. Fauci, a leading consultant for Biden management on infectious diseases. It was reasonable to assume that most people who were vaccinated were still safe, he said, “but the strength of the immune system varies from person to person.”
“We cannot guarantee that a person who has been vaccinated against smallpox will still be protected from monkeypox,” he said. Fauci.
The monopoly outbreak has grown to include about 260 confirmed cases and the largest number investigated in 21 countries.

In the United States, the Centers for Disease Control and Prevention is tracking nine cases in seven provinces, not all of which have a history of traveling to countries where monkeys abound. That suggests there may be some degree of public transmission, Drs. Rochelle Walensky, director of the organization, told reporters Thursday.
Drs. Walensky said 74 laboratories in 46 provinces could test monkey sightings, and together they could test up to 7,000 samples a week. The organization is working to increase that capacity, he said, adding: “We have been preparing for this kind of outbreak for decades.”
Monkeypox infection begins with respiratory symptoms but blooms into a distinct rash, first in the mouth, then in the palms of the hands and soles of the feet, and gradually throughout the body. The eruption eventually rises, growing into red bubbles.
Each pustule contains a live virus, and a broken blister can contaminate bed linen and other items, putting their loved ones at risk. People with the virus should be very careful when rubbing their eyes because the virus can kill the sight.
“Before Jenner developed a vaccine for smallpox, the world’s first major cause of blindness was smallpox,” says Mark Slifka, an orthopedic surgeon at Oregon Health and Science University. He said people with the virus kept infecting each other until the scabies broke out and disappeared, he said.
Drs. Slifka and other experts have emphasized that while monkeys can be difficult and deadly, the current outbreak is unlikely to turn into a major epidemic.
“We are fortunate to have vaccines and treatments – things that can alleviate all that,” said Anne Rimoin, an epidemiologist at the University of California, Los Angeles, who studied monkeys in Africa. “We have the power to stop this virus.”
Monkeypox takes up to 12 days to cause symptoms, giving doctors the opportunity to go in for at least five days after exposure to vaccines and disease prevention. (The method, called post-exposure prophylaxis, is not an option for Covid patients because coronavirus can begin to destroy the body within a few days after exposure.)
The monocytes virus does not spread without symptoms. Careful monitoring, isolation of infected people, tracking their contacts and segregation of contact people should contain these outbreaks, says Drs. Rimoin.
The majority of those currently infected are men under the age of 50, with many identifying themselves as gay or bisexual, which may indicate the source of the disease at the Gay Pride event in the Canary Islands. (The outbreak is likely to start easily between people of the opposite sex at a major event, experts say.)
“The risk of exposure is not limited to one group,” said Drs. Walensky Thursday. “The important thing for us is to help everyone make the right decisions to protect their health and the health of their community, and that starts with raising awareness about science-led, not discriminatory.”
