<em>There is no evidence that kissing, hugging, sneezing, coughing, food, water, sharing eating utensils or drinking glasses, casual contact, or other contact without exposure to blood is associated with HCV transmission.</em>
PS - sorry I'm too out of it to look up refs for any of this today. It's not a good day - and this is *before* the injection - looks like a fun weekend..
Wrong. A is transmitted through fecal-contaminated food, never through sex. B & C can be transmitted through UNPROTECTED sex. There are studies that indicates 33% - 55% or higher unprotected sexual transmission rate for HCV. Studies that indicated the 2%-4% sexual transmission rate also indicates the study subject used condoms, hence these studies can be consider flawed, since condoms will reduce HCV transmission significantly. DUH!
There are no specific studies that show B is more sexual contagious than C, given the same amount of viral load. How infectious somebody is depends on his/her viral load.
Now I have given you somebody else to jump on. Please do and leave the people trying to help others alone.

Layla, I agree with you on this, someone needs to put their brain in gear before they speak.
On a positive note we woke up to about 8" of snow this morning in Spokane WA, looks beautiful. Shoveling it will be an experience on tx :)
Calm the f*ck down!
No one new can ask any ******* questions, cause if you do, it's off to the firing squad.
And no opinions allowed either, and no starting threads, and no opposing views, NAZI MOTHERFUCKERS!!!!!!!!!!!!!!!!
I heard Rush Limbaugh is back in business so you should have some closed minded right wing fodder to enjoy from him too.
Damn, another precious thread taken.
Tough ****.
WhEEEEEEEE, THIS IS FUN!!!!!!!!!!!!!!!!!!1
It may not offend you, but it sure as heck offends me. This site is to help us all get through treatment and assist each other as best we can. If we cannot be supportive, what's the point of being here.
Hope everyone is doing well with their treatments.
hepatitis-A <em>is</em> readily transmitted sexually. Fecal contact is necessary but food is certainly not the only form of transmission (see the CDC <a href="http://www.cdc.gov/ncidod/diseases/hepatitis/a/fact.htm">fact sheet</a>).
hepatitis B - <em>is</em> readily transmitted sexually (body fluids containing HBV are infectious (see the CDC <a href="http://www.cdc.gov/ncidod/diseases/hepatitis/b/fact.htm">fact sheet</a>
hepatitis C - <em>is not</em> readily transmitted sexually. See the CDC <a href="http://www.cdc.gov/ncidod/diseases/hepatitis/c/fact.htm">fact sheet</a>. For details on what "low-risk" means see a summary of the recent <a href="http://www.natap.org/2003/AASLD/day1_5.htm">HCV partners</a> study which reported 2.4% co-infection with the same genotype among monogamous couples who had been together at least 3 years. Within this 2.4% it is not clear whether the virus was actually passed from one memeber of the couple to the other or whether both happened to coincidentally share a common type. Viral sequencing is in progress. When complete it will show how often actual partner-partner transmission occurred (ie how much lower than 2.4% the true transmission rate is). Transmission excludes shared drug use but encompasses all types of couple contact including sexual contact and kissing. 17% of the 500 participants frequently/regularly used condoms so the rate of 2.4% or less may under-represent unprotected sexual contact. On the other hand that rate may overestimate strictly sexual transmission since it also includes other types of long-term couple contact (eg cohabitation).
If credible studies showing a 33-55% (or higher!) rate of transmission from unprotected sex with an hcv infected individual given the US viral mix actually existed: (1) they would be cited by recent reviews such as <a href="http://hepatology2.aasldjournals.org/scripts/om.dll/serve?action=searchDB&searchDBfor=art&artType=fullfree&id=ajhep0360s99#head4">this</a>(2) the CDC's guidelines would be different and (3) whoohoo would be able to find them.
Everyone should remember we all need suport!!!
Stop all this unnecessary badgering

Your CDC link DID NOT say that. YOU said that. The CDC link just shows all the possible ways that Hep A may be transmitted, but then anything is possible. I'm guessing they did so to cover all the bases, just to be on the safe side. The question here is not whether it is possible or not, but how LIKELY is it to get Hep A sexually? The CDC site did NOT address this, nor did it use the word "readily". Furthurmore, the CDC site clearly stated that:
"TRANSMISSION HAV is found in the stool (feces) of persons with hepatitis A.
HAV is usually spread from person to person by putting something in the mouth (even though it may look clean) that has been contaminated with the stool of a person with hepatitis A."
Willing, do you yourself (or your doctor, for that matter) know of even 1 person that got Hep A from sexual intercourse? Also, the recent Hep A outbreak from eating at a Mexican restaurant in western PA goes to enforce how Hep A is usually transmitted. Furthermore, how likely is it to ingest someone's feces when you're having regular sexual intercourse? I rest my case.
I find it amusing that you accusing someone with spreading misinformation, while you yourself is doing exactly that (repeatedly and consistently, I may add)!
Concerning Hep C transmission, go back and reread your own Hepatology link above CAREFULLY and THOROUGHLY, and you will see that that HCV tranmsission via sex listed in this link is very significant:
"How prevalent is the risk factor of sexual activity in acute hepatitis C?
The Centers for Disease Control and Prevention collects detailed risk factor data on cases of acute hepatitis C identified through the Acute Hepatitis Sentinel County Surveillance program. Between 1995 and 2000, 18% of individuals with acute community-acquired HCV infection reported sexual contact with an anti-HCV–positive person in the preceding 6-month period (two thirds of cases) or multiple sexual partners (one third of cases) as their only risk factor for HCV acquisition. Currently, sexual activity ranks as the second most common risk factor for HCV reported by individuals with acute hepatitis. This suggests that sexual transmission may contribute significantly to the total burden of HCV infection in the U.S. population."
Here, the 18% rate is just for a 6-month period. So a longer period, in terms of years, the rate would theoretically (and logically) be significantly higher. There are also various indications of very low % numbers for HCV transmission in this same study is for a PER YEAR basis, so for instance, if you multiply say 1%/yr for 30 years, you get a 30% sexual transmission rate for that 30 year period.
My HCV rate of 33% or higher is based on studies that I have posted here previously (post started by farmerjohn on 11/1/03). I recommend that you go back and read these studies. If you have problem with these studies, I sugguest you contact the authors of these studies, I'm just a messenger and also someone that happen to know how to read studies, something that apparantly you're not.
It is your prerogative to believe what you want to believe, but to accuse someone of passing misinformation when you are doing exactly just that is simply wrong.
Also, as the CDC guidelines make clear, to claim there is no difference between the risk of sexual transmission of HBV and HCV is misinformation.
The quote you selected from Terrault's review emphasizes the importance of carefully quantifying the risk of sexual transmission. This is hard because humans are not laboratory rats and it's hard to isolate sexual transmission from other risk factors. Studies like the "HCV-partners" study which have verified that hypothetical co-infections actually share the same genotype and have added controls to exclude other forms of transmission should be more credible than studies that haven't included these precautions. This is still an unresolved question however and, on this point, I suppose you're right: bias is not misinformation.
AK : I think the usual definition of chronic infection with HCV is detection of the virus 6-12 months after infection ((<a href="http://hepatology2.aasldjournals.org/scripts/om.dll/serve?action=searchDB&searchDBfor=art&artType=fullfree&id=ajhep0360s21#head4">see</a>).
Acute hepatitis is normally about 6 month. I believe everyone here has cronic HCV not acute. LL
Again, do you yourself, or your doctor, know of even 1 documented case of someone who got Hep A from straight sex?
Similarly, the CDC website did not provided any documented case at all of anyone who got Hep A through sex. I know of no one who knows a documented case of someone got hep A thru straight ******* around.
I'm always, and you should too, be wary of any website that do not provide legit references or legit studies to back up their claims. I notice the website did not provide any references nor back-up data or studies. Also, just because it's in the CDC website, doesn't automatically guarantee that something is absolutely correct, or should be taking as cast in stone. Also, how often do they check and update these info. Heck, for all I know, the website info could have been been put up a web gov bureaucrat, and not doctors. Medicine is constantly changing field as new discoveries and new findings are made, and old info get obselete.
I encourage you to print out this CDC page on Hep A and show it to your doctor, or better, several doctors, and see what their responses will be. You'll be surprise.
As far as I'm concern, to make a claim without veriable legit backup info or legit studies is spreading misinformation, like what you're doing.
"Also, as the CDC guidelines make clear, to claim there is no difference between the risk of sexual transmission of HBV and HCV is misinformation."
Where in the CDC site that show there is differences in risk for B & C?
The site clear shows that they're both blood-borne diseases, as oppose to A, which is a food-borne disease, and can be transmitted sexually. How's that different?
Again, you're up to your spreading of misinfo **** again by accusing other of misinfo.
Increasing this 15-20% by a considering a longer time period makes little sense: if you got the virus from sex with an HCV infected individual 5 years ago you would not be treated for symptoms of acute HCV now. As you point out, the acute period of infection is limited to about 6 months.
As discussed in the above CDC report, there is a wide discrepancy between the acute risk-factor data and the monogamous transmission data. The obvious implication is that as the studies add more controls : one partner, few additional risk factors, and concordant co-infection, the estimate for the rate of transmission goes way down. We'll never get to Terriri's hypothetical box so we'll probably never know the "true" transmission rate but there's no basis in the Sentinel County data to assume it's <em>higher</e< than 15-20%.
1% would be the risk for each and every sexual encounter. The risk is not additive...that is 10 sex acts doesn't amount to a 10% accumulated risk the risk on the 11th or 1000th encounter is still 1%. You cannot multiply the relative risk by number of years and get a "new" realtive risk rate....well I guess you can but it si not correct...back to basic stats for you!!!

"for hetero mono couples the estimated risk is ZERO to .6% annually"..which means there is some consideration whether it can be sexually transmitted at all,up to about 1 in 200..I've seen the estimates also at 2% over 20 years..thats 1 in 1000 per year..also:Can I give hepatitis C to my sex partner?
Yes, but it is not likely. Compared to hepatitis B virus and the human immunodeficiency virus (HIV), it is less likely that you will spread the hepatitis C virus to your sex partner.
If you have one long-term sex partner, you do not necessarily need to change your sex habits. But, if either you or your partner is worried about the small chance of spreading the hepatitis C virus, you can use latex condoms. This will make it almost impossible to spread the virus. Long-term partners of people with hepatitis C should get tested for the virus. If the test is negative, you will probably not need to repeat it.
and on this site:I appreciate your rather succinct question. Several studies have looked for the hepatitis C viral RNA in human semen. All of the studies I consider to be reputable have not been able to find it. I hope this is a succinct answer to your question.
Well please let me know.
Thank you
Lindsay
