contact precaution only
droplet precaution only
contact and droplet precautions

Explanation:

COVID - 19 can spread through close contact (contact precautions), through respiratory droplets (droplet precautions). While there was some initial debate about airborne transmission, the primary recognized precautions for hospital facilities as per CDC and WHO (in the initial understanding and standard precautions setup) included contact and droplet precautions. Contact precautions prevent spread from direct or indirect contact with the patient or their environment. Droplet precautions prevent spread from large - particle droplets (e.g., when a patient coughs or sneezes).

Answer:

Contact and droplet precautions.
