“Extra data on its prevalence, persistent signs and threat elements might assist healthcare professionals allocate assets and companies to assist lengthy haulers get again to regular lives,” stated Wu.
Whereas commending the efforts of the analysis to determine elements related to lengthy COVID, Alain Lekoubou Looti, a neurologist at Penn State College advised the Los Angeles Instances, “Nonetheless, these elements might should be confirmed in bigger samples.”
