Option A) True; The highest risk of disease transmission is unprotected direct or indirect contact with infected blood.
Airborne transmission differs from droplet transmission in that it refers to the presence of microbes within droplet nuclei, which are typically thought of as particles with a diameter of less than 5 m and have the ability to float through the air for extended periods of time and spread to people more than 1 m away.
As it relates to COVID-19, certain situations and settings where procedures or support treatments that produce aerosols are carried out, such as endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation prior to intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, non-invasive positive-pressure ventilation, tracheostomy.
