How big is the monkey pox genome compared to the corona genome? What are the latest hypotheses about the spread of the virus? What does it mean to discover two different species of monkey pox in the United States?
Two different species of monkey pox have been discovered in America
New ranking data from the US Centers for Disease Control and Prevention have revealed the prevalence of at least two genetically distinct monkey pox species in the United States, according to a report on NBC. The news was also announced by other media sources.
Although the centers have not listed all 22 confirmed cases in the US so far, two of them were found to be genetically similar to an infection that infected a Texas man who traveled to Nigeria in 2021, and both cases two people who recently traveled to Africa: a woman from Virginia and a man from Florida.
The rest of the serial cases in the US are similar to the genetic case codes in Europe and a 2021 infection in a Maryland resident who traveled to Nigeria.
“Although they are similar to each other, their genetic analysis shows that they are not related to each other,” said Jennifer McQuiston, deputy director of the Center for Pathogenesis and Pathology, on these two variables – at a conference. for the press on Friday. .
Two outbreaks of monkey pox
McQuston and other disease experts added that this new information shows that cases in the United States are caused by “two outbreaks” rather than one, complicating our understanding of their origin.
“It is possible that in the last two years, there have been at least two different cases where the monkey pox virus has been transmitted to humans in Nigeria by the animal that carried it, and it is possible that the virus has spread through a close person. contact with the person .. can be intimate or sexual contact.
This possibility, in turn, raises questions about how long monkey pox has spread outside Africa and the extent of virus transmission.
“This is like a new TV series and we do not know what episode we are in,” said Ann Rimoen, a professor of epidemiology at the Fielding School of Public Health at UCLA. “Now we’re just starting to get a piece of the origin. History.”
Nearly 900 cases of aphids have been reported outside Africa since the beginning of May, according to Global Health, a group that collects data on infectious diseases. Prior to that, the largest outbreak in the Western Hemisphere was 47 cases in the United States in 2003. These people became infected with domesticated prey dogs and no human-to-human transmission has been documented.
4 hypotheses about monkey pox
Experts are examining various possible explanations for the rapid increase in current eruptions and there are 4 possibilities:
- The course of events gave the virus an opportunity to spread.
- The line of monkeys has evolved to be better at human-to-human transmission.
- The virus may have spread undetected for some time.
- Increased pressure on ecosystems may be responsible for the spread of monkeypox infection to humans.
The fourth possibility was mentioned by World Health Organization expert Mike Ryan – last Wednesday – and Ryan said in Geneva, “We are dealing with a major instability at a common point between animals and humans.” There are other diseases that originate in animals and are more common in humans, such as Lassa fever and the Ebola virus.
Regarding the third possibility, the Director General of the World Health Organization, Tedros Adhanom Ghebreyesus, suggested that it is possible.
On the idea that the virus has become more contagious, Andrew Reed, a professor at Penn State University studying the development of infectious diseases, noted the fact that monkey pox appears to spread between close contacts more efficiently than scientists have observed in past.
How big is the monkey pox genome compared to the corona genome?
Monkeypox is a DNA virus that does not change as fast as RNA viruses like the Corona virus, but Reed noted that DNA viruses have a long genome: the apex genome of monkeys is 7 times larger than that of Corona virus.
“The fact that he has so many genes to play with means that all sorts of things can happen,” he said.
Stephen Morse, a professor of epidemiology at Columbia University, said it’s worth checking if one variant spreads more easily than the other.
77 cases of smallpox in Canada and the situation in Quebec is worrying
Canada had counted – as of Friday – 77 confirmed cases of smallpox, almost all of which were discovered in Quebec, where authorities considered the situation “alarming”.
Canada reported the first two cases on May 20 in the French-speaking province.
Dr. Howard Ngo, a Federal Public Health Agency official, told a news conference that the situation was “alarming.” He noted that authorities feared, in particular, the “emergence of cases” that would spread among “families and affect pregnant women or young children”.
He also stated that this diffusion is not limited to “a specific group or environment”; Thus it can affect “anyone, regardless of their gender identity or sexual orientation”.
The province has received smallpox vaccines that may be effective in protecting contacts with monkeypox patients.
There is currently no treatment or vaccine available to fight this virus, but smallpox vaccination has proven very effective in preventing monkeypox.
France reports 51 cases of monkey pox
Yesterday, Friday, French health authorities announced the discovery of 51 cases of monkey pox, amid an increase in the number of confirmed cases worldwide.
Paris reported the first injuries last May, and the total number of confirmed cases last Wednesday was 33.
The French Public Health Authority said all injuries were recorded in men between the ages of 22 and 63 and that only one person was admitted to hospital and subsequently released from it.
Health officials: It’s too early to say monkey pox will turn into an epidemic in America
U.S. health officials urged doctors – yesterday, Friday – to conduct tests for monkey pox if suspected, saying there could be a worldwide outbreak, but it is too early to say whether the disease will turn into a pandemic, added that the risks to public health remain low.
Officials from the U.S. Centers for Disease Control and Prevention told reporters at a conference call that 21 cases of the disease have been reported so far in at least 11 states, with isolated patients to help prevent infection.
