Brazil has found different genetic sequencing of the virus, with four more people in the United States dying of new coronapneumonia.

The number of new cases of pneumonia in the Americas continues to increase, Washington state health officials announced Tuesday that four more people in the state have died of new crown pneumonia.
Brazilian researchers' genetic sequencing of the virus showed that the virus was different in two confirmed cases in Brazil.
Four more people died of new pneumonia in Washington state, but the four deaths were not previously included in the U.S. Centers for Disease Control and Prevention statistics, Jeffrey Duchin, a health official in King County, Washington, said at a news conference Tuesday.
the U.S. Centers for Disease Control and Prevention released data on the 2nd, as of the 1st, there are 91 confirmed or presumed positive cases in the United States, there are 2 deaths.
presumed positive cases are those that have tested positive in some laboratories but have not been confirmed by the CDC.
Ontario Health announced on the 2nd confirmed three more cases of new coronary pneumonia.
the cumulative number of confirmed cases in Canada has increased to 27.
Brazil's Ministry of Health on the 2nd, the latest data released, there are currently two confirmed cases in Brazil.
researchers at the Adoflu Lutz Institute in Brazil and the Faculty of Medicine at the University of Sao Paulo genetically sequenced the viruses in the two cases and found that the viruses in the first case were more similar to those found in Germany, while in the second case the viruses were more similar to those found in the UK.
are also different from viruses found in China. Both patients returned to Brazil in February after contracting in Italy,
reported. Estelle Sabino, a researcher at the University of S?o Paulo School of Medicine,
, said the mutation in the virus is a mark left by the spread of the outbreak in the area concerned and can be used by researchers to track the path of the virus's spread.
a new virus has mutated? According to the latest discovery in Brazil, there is a clear difference with the Chinese virus gene samples ,History Hall: March 1, Brazil came to the news that the new virus may have mutated! According to medical research in Brazil, Italy and elsewhere, local tests of the new virus show that there is a marked difference between the initial virus samples in China, and the medical community is seeking to share more information in an attempt to more effectively stop the changing virus.
the new virus is gradually affecting the world, South America's Brazil on the 26th appeared "first confirmed", and the biggest problem is that preliminary research found that the virus in Brazil is likely to have mutated.
, there have been two confirmed cases in Brazil, 1,709 confirmed cases in Italy, and confirmed cases in several European countries that may be linked to Italy.
but the biggest technical discovery came from Brazil, where scientists worked with British scientists to urgently sequence the "coronavirus gene" of the 61-year-old Brazilian patient, which would have taken 15 days to complete in 48 hours.
and found that "unlike three of the previously published viral genes, the virus may have mutated."
the first case of a 61-year-old male patient from Sao Paulo, Brazil, in the first case of a 61-year-old male patient in Sao Paulo, the first case of a new coronavirus report in South America.
the team took the virus gene from the patient's nasopharynx and analyzed it.
the patient had travelled to Lombardy, northern Italy, from 9 to 21 February 2020, and on his return to Brazil he developed fever and respiratory symptoms, including a dry cough, a sore throat and a runny nose.
the government of Sao Paulo, the first time in South America that a genetic sequence of a new virus has been analyzed, by the Adolfo Lutz National Institute of Research in Brazil, the National Reference Laboratory, and the University of Sao Paulo (USP) and the University of Oxford's Institute of Tropical Medicine.
's research team says only one genome sequence has been published in Italy, from a female tourist from East Asia, in a case of "outbound migration."
But with the growing number of "homecases", it is necessary to re-analyze the virus for native Cases in Italy.
" Lombardy in northern Italy, just where the first native case of Italy has occurred, so the virus genes we analyzed may represent new findings, including mutations in the virus."
" the report noted that preliminary genetic analysis showed that the genome of the Brazilian "Brazil/SPBR1/2020" virus was three different from the "Hu-1 reference strain" published in China, indicating that the virus had begun to mutate during transmission.
of these mutations, two are the closest sequences to the now known virus, the cluster infection of "Germany/BavPat1/2020" in Munich, Germany.
the results suggest that the spread in Europe is already different from the virus that originally spread in China. For Brazil, analyzing how these viruses spread and how they mutate, the team said, is more certain about whether they will spread domestically, how to avoid cluster infections, and better know how to control countries that may transmit the virus.

research team will make the information public, hoping that countries can share the results of research, in an effort to stop the virus from spreading in the absence of a clear lack of clarity, triggering more uncertain mutations.
