Dr. Anthony Fauci, the nation’s top infectious disease expert, says that a new study could explain that wide range in severity of COVID-19 symptoms that different patients experience, The Miami Herald reported.
Since the beginning of the pandemic, doctors have been baffled about the unpredictable ways in which SARS-CoV-2, the pathogen currently being referred to as the “novel coronavirus,” affects different patients. Some have no symptoms, some have mild ones, some severe, and in some, the illness is fatal.
Now, Fauci says, a new study published in the journal Science could possibly explain why.
SARS-CoV-2 is one of many pathogens in the coronavirus family, and not all of them cause fatal illnesses. Indeed, many of them cause nothing more than a mundane common cold.
And when a virus invades a person, the body’s immune system deploys a variety of tools to fight both the current infection, and to guard against a repeated one. Those tools include antibodies and T-cells.
