Factors affecting the risk of disease transmission during fine-needle aspiration cytology

Dear Editor, We read with interest the article “Assessment of the risk of disease transmission during fine-needle aspiration cytology under ultrasound guidance by visualization of droplet and aerosol formation” by Konno and colleagues [1]. [...]any droplet generation from the exiting vibration will be only from the tip of the needle and not from its side. Declarations Conflict of interest Alessandro Caputo, Valeria Ciliberti, and Pasquale Cretella declare that they have no conflicts of interest.
