The United States has now identified 45 monkey cases in 15 states and the District of Columbia, and the multinational epidemic has been confirmed in more than 1,300 cases in at least 31 countries. No casualties were reported.
At a news briefing on Friday, U.S. health officials provided updates on efforts to stem the spread of the virus and dispel unfounded fears that the virus is spreading through the air.
To date, there have been no reported cases of airborne transmission in the epidemic, which has spread almost entirely through the sexual networks of men who have sex with men. Smallpox can be spread through large, short-distance breathing drops, and health workers are encouraged to wear masks and take other precautions during special procedures, such as intubation. However, the overall potential for diffusion through small, long-range aerosols is much more speculative and theoretical.
Rochelle Valenski, director of the Centers for Disease Control and Prevention, said in a briefing: There was no evidence that his casual conversation was spread by passing someone in the store or by touching the same thing, such as a doorknob, he said.
Officials see the current epidemic spreading through “close, sustained physical contact,” he added. “This is in line with what we’ve seen in previous epidemics and what we’ve been studying for decades about this virus and the viruses around it.”
The CDC is still collecting clinical data on some of the country’s 45 cases, but all of those with data are directly related to physical contact, such as sexual intercourse, CDC officials said. Most of them are related to international travel.
“Everyone reports the type of close contact that can occur with direct skin contact,” Jennifer McQueiston, deputy director of the CDC’s Highly Dangerous Pathogens and Pathology Division, said at a briefing. “It’s hard to tell what a face is [respiratory] The passage of droplets can be similar to direct contact with the skin, because people are very close and intimate with each other. However, all of our patients reported direct skin contact. ”
Officials have highlighted the possibility of airborne transmission, comparing it to communication disruptions in the COVID-19 pandemic after The New York Times reported the controversial incident earlier this week. Virologists and health experts noted that there was evidence that monkeys were infected with smallpox through the air The best is thin-and certainly not the main method of transmission. There is also an article increase stigma around infectionSome said which health authorities were trying hard to avoid it.
In addition, Valensky noted, unlike the novel coronavirus, which public health workers and virologists have tried to understand during the mushroom pandemic, experts have decades of experience with monkeys. The virus was first identified in monkeys in 1958, and the first case in humans was observed in 1970. The virus is endemic and has appeared periodically in Central and West Africa, where it is present in animals. For example, in addition to the multinational epidemic, more than 1,400 confirmed and suspicious cases, including 66 deaths, have been reported in endemic countries this year.
While airborne infections are not a major concern, health officials are vying to stop the current epidemic and urge people to take it seriously. Earlier this week, the World Health Organization called on countries to “make every effort to identify all cases and links to control this epidemic and prevent its further spread.”
WHO Director-General Tedros Adhanom Gebrejesus said: “The risk of developing smallpox in non-endemic countries is real.”
Although the disease is more common in men, that is, men who have sex with men, the virus can spread to all people. A small number of cases have been reported in women so far. “The WHO is particularly concerned about the risk of this virus to vulnerable groups, including children and pregnant women,” Tedros said.
At a briefing on Friday, Valensky and other federal health officials highlighted some of the work involved in the epidemic. It begins with an effort to raise awareness of the disease and its appearance and sensations. Cases should not be investigated, treated or monitored until people know what to look for.
In this epidemic, smallpox is largely the same as before, but not completely: a disease that occurs 5-21 days after prolonged physical contact with an infected person. Typhoid fever usually begins with a flu-like illness, which is preceded by rashes all over the body, including on the face, palms, and soles of the feet. The sores begin to flatten out, but then rise, fill with fluid, and turn into scabs. It contains a large number of viruses and the virus spreads in direct contact with them, in their fluids or in materials contaminated with wounds. When a person is considered non-infectious, when all the wounded scabs fall off and a new layer of skin appears.
