First, Paxlovid is the "go-to" antiviral treatment for COVID. For mild to moderate infections, it can mitigate/prevent escalation of infection to a more severe case. However, it must be taken within 5 days of infection for it to be effective (bc viral spread happens faster at beginning of infection)
Paxlovid "may" be taken again after a new/separate infection occurs (not a COV(ID "rebound"), but treatment options differ per each person... plus there are qualifications (i.e., age, underlying conditions, etc.) that the healthcare system will apply, so doctor would prescribe accordingly.
Stepbro said they were all given antibiotics until the test came back positive.
Wouldn’t hurt (not knowing what the diagnosis was, pending testing) but won’t help. COVID is a viral infection, and antibiotics are ineffective in treating COVID. Early on in the pandemic, before treatments were found for COVID, they tested antibiotics but proved ineffective, as suspected.
