Measles seems to be more dangerous to us than scientists themselves once suspected.
The measles virus is one of the most contagious human pathogens of choice, and is inherently very dangerous, sometimes affecting us with fatal complications such as pneumonia and encephalitis.
Now, the effects of measles extend even further by causing the immune system to suffer from amnesia.
Researchers analyzed the blood of unvaccinated children before and after a measles outbreak in the Netherlands and found that the virus erases the body’s memory of previous pathogens. The paper was recently published in Science Immunology and Science.
The two technical approaches reveal how this type of infection compromises the autoimmune analysis system months or years later, causing the student’s body to “forget” past antibodies to other pathogens.
If we don’t get through these antibodies, children lose most of their immune defenses and become more vulnerable to viruses that affect them and that they themselves have already encountered and overcome. We have found strong evidence that the measles virus is actually destroying the immune system, said Stephen Elledge, a researcher at the Howard & Middot; Hughes Medical Institute.”
The extent to which this immune amnesia increases the risk of death from the infection is unclear. But experts and scholars in infectious disease management believe that the findings of the study analysis are another good reason to immunize children against the virus. Because of under-vaccination and misinformation about vaccine safety, measles cases are increasing dramatically – by more than 30 percent globally from 2017 to 2018.
If need be we can allow (measles) outbreaks, we’re intentionally creating companies of people who are also susceptible to other related diseases, Velislava Petrova of the U.K.-based Wellcome Sanger Institute, who led one of the studies, said.
You can’t be unaware of the new danger of measles
1. The hidden “eraser”
Measles-related viruses are among the most contagious and potent viral problems scientists have ever seen. Before a vaccine was developed in 1963, measles caused 3 to 4 million cases in the United States each year. But that number plummeted over the next few decades – in 2000, when the disease was declared eliminated in the United States, only 86 cases were reported.
But that’s when measles made a comeback,德國麻疹是什麼，What is this disease? 1) It is a short-term illness caused by the rubella virus, 2) It is easily transmitted through droplets from an infected person, 3) It is most contagious during a rash outbreak, but an infected person can transmit the virus from 10 days before a rash outbreak to 15 days after a rash outbreak。 often ending up in epidemics in unvaccinated communities. On October 3 of this year, the U.S. Centers for Disease Control reported 1,250 cases.
Data compiled by the World People’s Health Services also show that measles continues to infect more than 7 million people worldwide each year, killing more than 100,000, due to the inability of companies to vaccinate through access to Chinese vaccines and refusals to vaccinate.
Previous research methods have hinted at the impact of this mental illness far beyond the scope of the infection.
Harvard virologist Michael Mina, who participated in the study, published a study in 2015 suggesting that measles may suppress the immune system of infected individuals for two to three years, leaving them vulnerable to other diseases. The researchers hypothesized that measles could lead to “immune amnesia,” in which the body forgets that it has been exposed to a pathogen.
However, the hypothesis is still controversial, and key technical questions include: If immune amnesia is real, how does it develop in a business, and how severe is it?
Now, an international team of researchers from Harvard Medical School, Brigham University, and singles from the 2011 Rotterdam Open has found the answer.
In one of the studies, researchers analyzed blood samples from 77 unvaccinated Dutch children before and after they contracted measles. The results showed that the measles virus cleared 11% to 73% of the protective antibodies in these children. These antibodies “remember” previously infected pathogens to prevent the body from becoming infected again. This includes a wide range of network viruses and bacteria, from influenza to herpes viruses, to bacteria that can cause associated pneumonia and skin infections. The paper was published in Science.
