ological bases of droplet transmission, the movement of passengers and crew, and indirect contact via fomites. Of note, five case reports of illness tracing from transmissions on airplanes (one case of SARS and four cases of influenza) found that 40% of the transmission occurred outside of the two-row zone, suggesting that move-

Droplet transmission is a form of contact transmission when some form of infectious agent is transmitted by droplet route (direct or indirect contact).

Surgical face mask must be worn within 3-6 feet of an individual with a respiratory infection; and b. Gowns and gloves should be worn if HCW is touching surfaces

M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2). M. tuberculosis. is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter.

This section outlines recent evidence underlining the significant and primary role aerosol transmission plays in the spread of SARS-CoV-2. 1.

The Difference Between Droplet and Airborne Transmission BC Ministry of Health Humans produce droplets in various ways (e.g. sneezing, coughing, singing) and these droplets vary in size. Large droplets (> 5 µm) comprise most of the volume of expelled respiratory droplets and they tend to fall rapidly to the ground.

Other pathogens can enter the body through droplet transmission, which occurs when a person inhales droplets from an infected person, such as through a cough or sneeze. Vector-borne transmission occurs when an infectious source, such as an animal bite or an insect bite or sting, penetrates the body’s skin. Time: 35 minutes

Wuhan, China.3 These hypotheses included an assumption of transmission based on the experience of SARS-CoV in 2003 and centered on droplet transmission at close range. During the 2002-2003 pandemic, SARS-CoV was shown to have airborne disease transmission potential.4 COVID-19 has developed into a pandemic more severe than SARS in 2003.
