What Does it Mean for a Virus to Be “Airborne”?

The video explores the concept of airborne viruses, explaining that not all viruses traveling in droplets are considered airborne. It delves into the physics of droplet sizes, the biology of viruses, and clinical data to define airborne diseases. Examples like measles and HIV illustrate the criteria for airborne classification. The video also discusses the ongoing research on COVID-19's airborne potential, emphasizing the need for protective measures and the scientific debate surrounding it.

What is the primary reason for the debate over the definition of 'airborne' in the context of viruses?

• The size of the virus particles

• The disagreement among experts on the term's meaning

• The type of masks used for protection

• The speed at which droplets travel

Which of the following is NOT a requirement for a virus to be classified as airborne?

• The virus must be present in respiratory droplets

• The virus must be viable in droplets

• The virus must be expelled from the lungs

• The virus must be able to infect tissues it reaches

Why is measles considered an airborne virus?

• It meets all criteria for airborne transmission

• It can be transmitted through water

• It spreads through contact with surfaces

• It is only present in certain bodily fluids

What is a key factor still needed to determine if COVID-19 is airborne?

• The type of masks that are effective

• The infectious dose required to cause illness

• The speed at which the virus spreads

• The size of the virus particles

How might the classification of COVID-19 as airborne affect public health measures?

• It would change the type of protective equipment needed

• It would have no impact on current health guidelines

• It would require less protective equipment for health workers

• It would eliminate the need for social distancing
