A new study found that 2500 patients in France taking methylene blue at a dose of 75 mg three times daily as a cancer therapy had no reported cases of coronavirus, when they were interviewed on 27 March 2020.
In France on 27 March there were 1995 deaths from coronavirus so far (see here). By the Tomas Pueyo's formula, that means the number infected in France on that date would be 1.6 million people, which equates to 1 in 42 being infected at that time.
That means in 2500 people, you would expect to find 2500 / 42 = 59 people infected. Around half those infected with coronavirus show symptoms, so you would expect 59 / 2 = 30 cases of COVID-19 in this group of 2500 people.
But it was reported that none of these 2500 people showed any symptomatic signs of COVID-19.
This suggests methylene blue at the dose used may have effective antiviral effects against coronavirus.
Methylene blue is a stain used in microscopy. The anti-malaria drug chloroquine is a derivative of methylene blue; though methylene blue is actually less toxic than chloroquine.
Chloroquine is of course the drug which has been shown in vitro to be antiviral for coronavirus.
