Can norovirus be spread through saliva? how long are you contagious after vomiting stops?

Yes,: Norovirus spreads through contact with saliva or stool (the oral-fecal route of transmission). You are still contagious a few days after your symptoms resolve. See http://www.cdc.gov/norovirus/about/transmission.html Good hand washing and not sharing dinnerware or drinks is wise.

See below: Norovirus is mainly spread by fecal-oral route. The virus is shed in stool and also by airborne droplets of vomitus. You contract the virus by eating contaminated food or drink, by touching a surface thats been contaminated or by exposure to the vomitus. If a person recently vomited, saliva would transmit the virus. You are mostly contagious during the acute illness and for several days after.
