Novel coronavirus can be transmitted indirectly through objects in individual cases. The main mode of transmission of novel coronavirus is droplet transmission, i.e., close contact, generally within 1 m of the transmission risk is higher, such as more than 2 m can be transmitted through aerosol form. Its mainly in medical institutions when doing invasive airway operations, such as collection of pharyngeal swabs tracheal intubation, tracheotomy, bronchoscopy, etc., there may be aerosol transmission, which is spread over a long distance. In life such as within the family, indirect contact transmission through objects is not excluded, such as when the patient’s respiratory secretions fall on the surface of objects after discharge through coughing and before saliva drying, such as when other family members rub their eyes and nose after touching, there is a possibility of being infected. The main route of transmission of the new coronavirus is respiratory transmission, possibly through contact with objects. When taking delivery or take-out, there may be other people’s respiratory secretions on its outer packaging, so it is recommended to remove the outer packaging and wipe it with 75% alcohol.
