Coronavirus penetrated to Spain, one of the most affected by infection countries to date, in February. However, to establish the patient zero is not possible due to the large-scale spread of the virus in the country. To such conclusion scientists from the Institute of health Carlos III in Madrid, writes El Pais.
Spanish scientists studied the genomes of SARS-CoV-2 and identified three groups of viruses that spread in the country S, G and V. Where the virus first emerged in Spain in mid-February, he was found in samples taken from infected people in Valencia. All analyzed viruses refer to the genome of Wuhan, discovered on November 24.
Presumably, the coronavirus from Spain has spread to six other countries, and to get into the country at least 15 different ways.
they Also found that viruses are not heavily mutated, so the vaccine for the coronavirus will be effective. According to one of the researchers, SARS-CoV-2 mutates significantly slowly than the flu virus or HIV infection.
According to Johns Hopkins University on April 25, in the world of coronavirus has infected more than 2,789 million people, including more than 195 thousand died about 780 thousand were cured. Spain is in second place for the number infected with an indicator of the 219 thousand people. The mortality rate exceeds 10 per cent (died 22.5 thousand people).
