After publication of this work [1], we noted that we failed to include the complete list of all coauthors. The full list of authors has now been updated. The Authors’ contributions, Acknowledgements and Competing interests section have been modified accordingly. We are publishing this erratum to update the author list, which is as follows:

Florence Bretelle, Florence Fenollar, Karine Baumstarck, Cécile Fortanier, Jean François Cocallemen, Valérie Serazin, Didier Raoult, Pascal Auquier, Sandrine Loubière, and the Groupe de Recherche en Obstétrique et Gynécologie.
