Debbie asks "I know two different people who had COVID. One with just a cold. The other required hospitalization. Could the newest strain do this, or could there be two different strains out there?"

Several subvariants of the omicron strain are currently circulating. 

Though omicron subvariants are more easily spread, they tend to cause milder disease than prior variants like the original coronavirus or Delta. 

Whether someone gets really sick from COVID depends on a number of factors including their vaccination status, their underlying health, and whether they take anti-viral medication after testing positive for COVID.
