As of January 4, 2023, there is no data showing that Professor Barrick was infected with the new coronavirus.
Ralph Baric, male, American, professor of epidemiology at the University of North Carolina, is known as the father of coronavirus.
In 1989, Barrick disclosed his research on viral gene recombination. In 2003, Barrick cloned an infectious strain of the SARS virus at the Fort Detrick Biological Laboratory. In 2004, Barrick's team began research on SARS virus reverse genetics and has received funding from the National Institutes of Health for many years.
On November 25, 2008, the Barrick team published a paper "Synthetic recombinant SARS-like coronavirus is infectious to cultured cells and experimental mice" and introduced the strength of its team: Now we have the ability to design, Synthesis of various SARS-like coronaviruses. In November 2015, Barrick's team published a paper stating that they had successfully produced a chimeric virus that was infectious to human cells.
Characteristics of the new coronavirus pneumonia
According to the existing case data, the main symptoms of new coronavirus pneumonia are fever, dry cough, fatigue, etc., and a few patients are accompanied by nasal congestion, runny nose, Diarrhea and other upper respiratory tract and gastrointestinal symptoms. Severe cases often develop dyspnea after 1 week, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, difficult-to-correct metabolic acidosis, coagulopathy, and multiple organ failure.
It is worth noting that severe and critically ill patients may have moderate to low fever or even no obvious fever during the course of the disease. Mild patients only show low-grade fever, mild fatigue, etc., without pneumonia. Judging from the current cases treated, most patients have a good prognosis, while a few patients are in critical condition. The elderly and those with chronic underlying diseases have poorer prognosis. Children's cases have relatively mild symptoms.
