After the new Corona virus has become a threat to the whole world, more than a year since its appearance, all of us are looking forward to knowing what happens every minute, in light of the tremendous development that Covid-19 has brought in our lives.
“Masrawy” provides a daily service to display everything you want to know about the developments of the emerging corona virus, first-hand, from the emergence of new symptoms or the occurrence of a different mutation, as well as the development of vaccines and drugs, in brief.
One dose of the vaccine is enough
While vaccine developers have been busy working on producing what can stand against the emerging corona virus and its mutations, other experts have worked to study the effectiveness and effects of regular vaccination.
Between research and another, two recent studies indicated that people recovering from the epidemic do not need more than one dose of the vaccine produced by “Pfizer” or by Moderna Corporation with DNA technology, because the amount of antibody, that is, immune proteins capable of killing the virus That they are generated by the first dose, far exceeds that generated by those who did not have the epidemic and took two doses of the vaccine.
The first study was conducted by a team of researchers at the Swiss University of “Neuchatel” on the immunity of health personnel in 4 hospitals, some of them are free of the virus, and others were not infected with it in the first place, according to the “Al Arabiya” website.
Global health explode a surprise
As the search for information about the source of Corona continues, the joint mission of WHO and China experts announced, Tuesday, that there is insufficient evidence to confirm that the emerging virus was spreading in Wuhan, central China, before December 2019.
“There is no indication of SARS-Cove-2 transmission in the population in the period leading up to December 2019,” China team leader Liang Wanyan said at a press conference.
He also added that “there is not enough evidence” to determine whether the virus had spread in the city before that.
To that he pointed out that the transmission of infection from an animal is likely, but so far, “the host has not yet been identified,” according to the “Al-Arabiya” website.
Development of a new smartphone accessory to detect “Corona”
A team of French scientists has developed a diagnostic device called “Cordial for Covid”, capable of detecting the presence of the Corona virus within minutes using a smartphone.
Scientists at the Institute for Electronics, Microelectronics and Nanotechnology (IEMN) have developed the device that looks like a flash drive, in which a strip is inserted with a sample taken by a swab from a patient’s nose.
Then the device with a special sensor built into the smartphone is connected to the smartphone, and after 10 minutes, the test results will appear on the screen of the device, according to “Sputnik”.
