Can you pass norovirus through air?

Yes, you can get norovirus through the air, primarily from aerosolized viral particles spread when an infected person vomits, which can be inhaled or land on surfaces, making airborne transmission a significant, though less common than contact/foodborne, route, especially in outbreaks, say CDC and other health sources, CDPH, and academic research. These tiny droplets can travel several meters and remain infectious, requiring careful cleanup.

Can you catch norovirus from breathing the same air?

Yes, you can get norovirus from breathing contaminated air, especially after someone vomits, as viral particles can become aerosolized and inhaled, but it's primarily spread through contaminated surfaces, food, water, and direct contact, not like a typical respiratory virus. When someone vomits, millions of viral particles can spread through the air, and if you're nearby, you can inhale or swallow these particles, leading to infection.
 

How long can norovirus survive in air?

Norovirus particles can become airborne, especially after vomiting, and remain suspended in the air for up to two hours, but they also easily contaminate surfaces and objects, where they can survive for days or even weeks. Because it's so hardy, proper cleaning with bleach and good hand hygiene are crucial to prevent spread, as alcohol-based sanitizers aren't effective against it. 

Can you be around someone with norovirus and not get it?

Yes, you can be around someone with norovirus and not get sick by taking strict precautions like frequent, thorough handwashing with soap and water (sanitizers don't work), disinfecting surfaces with bleach, avoiding shared food, and isolating the sick person, but it's extremely contagious and difficult to avoid entirely due to viral particles in vomit/feces and on surfaces.

Launder soiled fabrics in hot water and machine dry on high heat.
