PHILADELPHIA (KYW Newsradio) — To truly understand the danger of COVID-19, it helps to understand how the virus mutates.
The words “mutation” and “RNA virus” may be enough to make a non-scientist’s eyes glaze over in boredom, but the mutation of an RNA virus is at the core of the pandemic.
RNA viruses like SARS-CoV-2, which causes COVID-19, get into our cells and use them to divide and grow. And when our immune system attacks those viruses, they develop ingenious ways to change. That is why you can be exposed and fight off an RNA virus and, one year later, be victim to a slightly different version of the virus. This is why it is so important to continue to develop vaccines and medications to stay one step ahead
