Question

Maya lives near the sea and likes to have picnics with her friends on the beach. The beach is home to many gulls that carry the bacteria for the disease psittacosis. During one of these picnics, a gust of wind scatters sand and water, which is contaminated with gull droppings, into the air. Five days later, Maya and her friends all develop symptoms of psittacosis. Which mode of disease transmission could have infected Maya and her friends with the psittacosis bacteria?

A.
aerosol
B.
direct contact
C.
vector
D.
oral

Answer 2

A. Aerosol

Step-by-step explanation:

Aerosol transmission is when the pathogen is spread through the air, either by the transmission from the air to the person directly or by the pathogen being stored in the environment the infected organism was in.

Lets check the other answers just in case.

B. Maya and her friends did not directly contact the infected seagulls, so this is incorrect.

C. Vector transmission is by utilizing insects in order to transport the pathogen. While this was the cause of the bubonic plague, this is not the case for this transmission.

D. Oral is also not the answer, as they were not exposed by close contact with the infected seagulls. Unless they tried CPR on a seagull or ate an infected seagull, this is unlikely.

Hope this helps!
