We report the case of a cohort of 2500 French patients treated among others with methylene blue for cancer care.

During the COVID-19 epidemics none of them developed influenza-like illness.

Albeit this lack of infection might be by chance alone, it is possible that methylene blue might have a preventive effect for COVID-19 infection.

This is in line with the antiviral activity of Chloroquine, a Methylene blue derivative.

Both Chloroquine and Methylene blue have strong antiviral and anti- inflammatory properties probably linked to the change in intracellular pH and redox state.
