For several weeks, the world has been living in horror with the Coronavirus disease COVID-19. The anxiety caused by this unknown pathogen is not surprising. Yet, despite the media forecasts, is this virus such a great danger? Professor Didier Raoult tries to answer this question in his new book, Epidemics. Real dangers and False Alarms. It is to be released in May in France and is now available in electronic version. In it, the scientist reviews several epidemics of recent times that have aroused centuries-old fears: from the Mad Cow, through the Bird Flu, the H1N1 flu epidemic, SARS coronavirus, MERS coronavirus, Ebola, Anthrax, Chickenpox, Chikungunya, Zika, to this day Chinese coronavirus.
