American scientists have suggested that the Corona (Covid 19) epidemic will last for at least two years, and it will only be contained when a third of the world's population becomes immunized against infection.
Researchers from the Center for Infectious Diseases Research at the University of Minnesota said that controlling the virus is very difficult because it is transmitted by people who have no symptoms of the disease.
The medical report added that people who carry the virus may reach the peak of transmission to others, before symptoms appear, according to "Bloomberg."
Most countries of the world imposed restrictions on movement and closures in order to curb the spread of the disease, but governments have begun to allow reopening, cautiously, to reduce economic damage.
In the face of this return to open public places and production facilities, epidemiologists warn of a second outbreak and say that the epidemic may continue beyond 2022.
The report stated that officials should realize that the virus will not end soon, and people should also know that there may be a "seasonal outbreak" from time to time in the next two years. 2
Medical agencies are developing a vaccine against the Corona virus, but serum may be available in limited quantities only during the first stage.
And several scientific institutions have begun clinical tests for vaccines against infection, but they have to wait for several months to ensure that the vaccine does not cause any side effects.
Scientists fear that the temporary decline of the virus will allow a normal return to life, because this would lead to the return of the infection trend to what it was earlier.
In the case of the swine flu epidemic, in 2009 and 2010, the vaccine became available only after infections reached their peak in the United States.
