AI Thread Summary
The discussion centers on the effectiveness of alcohol-based hand sanitizers in inactivating viruses, specifically SARS and Hepatitis viruses. The CDC recommends hand hygiene practices, including the use of alcohol-based rubs, during a 10-day period for households with SARS patients. While alcohol is effective against SARS due to its ability to denature proteins and dissolve membrane lipids, it is noted that some Hepatitis viruses may not be effectively destroyed by alcohol. The conversation highlights the importance of following CDC guidelines, which are based on scientific testing, and raises questions about the specific types of Hepatitis viruses and their structural properties, particularly regarding their lipid envelopes.

From the CDC website: During this 10-day period, all members of the household with a SARS patient should carefully follow recommendations for hand hygiene, such as frequent hand washing or the use of alcohol-based hand rubs.

In the lab we always have to clean the surfaces to inactivate any Hepatitis viruses with a 10% bleach solution. Alcohol doesn't work, so why does the CDC recommend it?

because most people don't want to look like michael jackson and I'm pretty sure alcohol kills SARS.
 
Which hepatitis are you working with?

Alcohol acts on the protein by denaturing them and probably dissolve membrane lipids. Therefore the envelop and structure of the of the virus migth explain with some Hepatitis virus are not destroy by alchol whereas SRAS is destroy.

I think if the CDC says that alcohol can be used its because they probably tested. At least I hope they did, they are the one responsible for disease control.

Viruses have lipids?
 
the envelope surrounding the virus is made from membrane lipids. some have envelopes, some don't. I am not sure about hepatitis.
