The devil is in the details: In New York, no patient can be given hydroxychloroquine as an outpatients: this is per Cuomo’s executive order.
Thus, patients have likely been sick for at least a week, and in order to be hospitalized, they usually must have fever, respiratory compromise, or blood markers associated with severe disease.
Thus, in any New York study, we are looking at a sick population.
NoW, we know that when treating influenza with oseltamivir or baloxavir, TREATMENT MUST BE INITIATED WITHIN 72 HOURS OF ONSET OF SYMPTOMS.
Gilead has pointed out that their investigational drug, remdesivir, must also be given early in the Covid19 illness for a beneficial effect.
Uncontrolled observations of treating physicians is that hydroxychloroquine results is rapid resolution WHEN PATIENTS ARE TREATED EARLY IN THE DISEASE.
Thus, this result, in patients with advanced disease, is not surprising.
:In New York, no patient can be given hydroxychloroquine as an outpatients”
not true. (personal experience)
