COVID Airborne Transmission v. Monkeypox: Key Differences between viruses

-

By Aristos Georgiou

More than 1,000 cases of monkeypox have been confirmed around the world in several countries where the disease is not usually found - including the United States - raising questions about how the virus is spreading. But can monkeypox, a rare disease that is usually restricted to parts of Central and West Africa, spread via airborne transmission like the SARS-CoV-2 virus?

Some infectious diseases can spread through airborne transmission via tiny respiratory droplets known as aerosols that can become suspended in the air. These droplets are produced when an individual exhales, sneezes, coughs, talks, ar sings, for example. These droplets can contain live viruses ar other pathogens that can potentially infect healthy people if they land in the eyes, nose ar mouth.

Airborne transmission does not require face-to-face contact, and, in fact, an infected person does not even have to be in the sarne roam as another individual to infect them because the droplets can linger in the air for some time.

Several diseases spread through airborne transmission, including measles and chickenpox. Others, meanwhile, can spread, via larger respiratory droplets that do not float in the air as easily and fall to the ground faster.

SARS-CoV-2, spreads through, exposure to respiratory fluids containirig the infectious virus, and, while it was not clear in the early stages of the "COVID-19" pandemic, we now kri,ow that this can include aerosols.
