Variants in SARS-CoV-2 May Originate in Those With Fragile Immune Systems

Investigators continue to better understand why the novel coronavirus has experienced so many mutations in a short period of time. For example, a coronavirus most often mutates about twice per month, but B117, the United Kingdom-based variant of SARS-CoV-2, experienced more than 20 mutations since it was discovered. Some scientists believe this phenomenon results when people with weakened immune systems, such as those with cancer and diabetes, are infected. Because their immune systems cannot put up much of a fight, the virus easily mutates before it spreads to other individuals. While additional research is necessary, some public health experts suggest that those with compromised immune systems should be vaccinated first. Click here to read more.
