There are many circulating around the world, but health experts are mainly concerned with the appearance of three.
The virus can mutate through infection that infects people, and in order to make copies of itself. Some variations can be prejudicial to the virus and provoke its extinction, while others can prevent ventures and help them to expand.
“Not all mutations are current,” said doctor Mary Petrone, who studied infection at Yale University. “The virus will have suer de ves en cuando”.
Monitor the variants that are important for the likelihood that the vacancies and treatments will be less effective, or change the form in which it infects the population.
At the instigation of the pandemic, a mutational impulse to propagate around the world, but since then no one has made any notable changes, has been reported, Daniel Jones, a biologist at the Ohio State University.
One of the three main variants studied by the experts discovered in Great Britain in the finals of last year, and since then it has been detected in country teachers. In principle, the sanitary authorities do not believe that aggravation of information through recent information suggests that it is possible to do so, as it seems to be aware at the moment. It appears that it has been provided with more facilities, so that more hospitals and more hospitals can be left.
This variant can be converted to the dominant in United States in March, following the Centers for Control and Prevention of Paid Medicine.
Other detectives in South Africa and Brazil also have more contagious signals, report the experts.
At the moment, the data suggest that the current vacancies are effective if they are mutations, although it can be seen that their efficacy can be significantly reduced. There is some evidence that some treatment with anti-cancer agents has less effective effect on varying degrees.
There are ways to adjust vacancies and treatments by maintaining their effectiveness, said Dr. Anthony Fauci, the leading expert in infectious diseases in the United States.
The appearance of variants is related to the strains, and that the contagios from the virus have the opportunity to mutate and propagate. This is another reason why experts say the importance of using mascara and maintaining social distance.
“Many human beings carry the virus, less opportunities to kill,” Jones said.
