Is kissing someone while I have a cold sore any different than when I don't? (This is assuming I shed the virus identically with and without a sore.)

Is kissing someone while I have a cold sore any different than when I don't? (This is assuming I shed the virus identically with and without a sore.)

Herpes: You most likely are shedding more virus when you have an active sore and are therefore more likely to transmit the virus. The good news is that most people by reaching your age have already been infected with herpes type1 and you won't be giving them anything new. It would be best to refrain from any skin-to-skin contact with your sores until they are fully healed. ...Read more

My cold sore has healed and no visible wound from virus. Am I able to kiss my girlfriend or receive or perform oral sex. I never had virus on genitals?

My cold sore has healed and no visible wound from virus. Am I able to kiss my girlfriend or receive or perform oral sex. I never had virus on genitals?

HSV is still there: The problem with herpes - in this case HSV-1 - is that it is still present, and may be infective to someone who doesn't yet have the virus. In other words, you don't have to have the 'active volcano' of a herpes outbreak, as the virus can pass through what's called 'asymptomatic shedding'. The virus is capable of infecting through mucous membranes (lips, genitals, even the eye) or scratched skin. ...Read more

Am I at risk of contracting a virus If I kiss someone on the forehead and they have a cold sore on their upper lip?

Am I at risk of contracting a virus If I kiss someone on the forehead and they have a cold sore on their upper lip?

Low risk, but...: There is always a risk of catching or giving germs, viral or otherwise, when touching or being very near another person. That's the way life is. However, we humans much touch other humans. That's also the way life is. That said, cold sores are usually oral Herpes type 1, which is a virus that most people catch at some time. Many people catch it from their parents or siblings in childhood. ...Read more

If a person has oral herpes simplex virus 1 and their partner has it to, can they both be sexual active, like kissing when the cold sore heals?

Sure...: I suppose you cann't catch a disease that you already have. Given that, if you both have hsv-1, you don't have to worry about transmitting it to your partner...It's already there. ...Read more

If a person with a cold sore kissed me on the cheek, what are the chances I could contract herpes simplex virus 1? I washed it off 5-10 minutes after.

If a person with a cold sore kissed me on the cheek, what are the chances I could contract herpes simplex virus 1? I washed it off 5-10 minutes after.

HSV 1 is prevalent: More than 3/4 of people have HSV 1. It is quite likely that you have the virus already. If you have had a cold sore, ever, you have HSV 1. Even if you get it, it is not a big deal for an otherwise healthy person.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

2 week old baby got kissed on the forehead by my aunt who has a cold sore. What are the chances my baby will contract this virus now? I've never had 1.

2 week old baby got kissed on the forehead by my aunt who has a cold sore. What are the chances my baby will contract this virus now? I've never had 1.

???: Hard to say. I am sure you wiped it off ASAP after aunt not looking. The likelihood is questionable, as the forehead is not a moist surface and no membranes were involved. Greater risk if area then touched and fingers got into mouth or nose or eyes Do not hesitate to protect your child by advising -especially family- people not to kiss child when a sore is present. They don't like it - too bad. ...Read more

I have a cold sore that mostly healed. I shared a fork w/ my boyfriend & had oral sex, receiving. Is it a possibly he could have got/spread the virus?

I have a cold sore that mostly healed. I shared a fork w/ my boyfriend & had oral sex, receiving. Is it a possibly he could have got/spread the virus?

No significant risk: Oral herpes is transmitted only by contacting someone with your mouth, i.e. by kissing or performing oral sex. In theory maybe by utensils and shared drinking glasses, but this is rare. Contact with your genital area connot transmit it unless you also have genital herpes. Also a "mostly healed" sore probably is no longer infectious, but in future best avoid all contact until totally healed. ...Read more

How long does it take to develop lesions after exposure to cold sores? My boyfriend has developed cold sore blisters and I think I have been exposed. How long before I can expect to see blisters forming if I do have the virus?

Week to 10 days: In addition the best time to treat a cold sore is before you see it. A tingle or itch will usually start first in the lip area and that is the time to start whichever medication your doctor recommends. ...Read more

My boyfriend of a year has a herpes cold sore on his lip and he says he has never had it before. I don't have the virus. Can hsv-1 be dormant for years and suddenly outbreak?

My boyfriend of a year has a herpes cold sore on his lip and he says he has never had it before. I don't have the virus. Can hsv-1 be dormant for years and suddenly outbreak?

Absolutely: Most people are infected with oral hsv as children and can indeed lay dormant for years and then emerge. You may even have it and not realize it, unless you have had antibody testing that is negative. Also, oral herpes and genital herpes are two separate viruses so this doesn't necessarily mean that he has been unfaithful or performed oral sex on someone else or anything of the sort. ...Read more

My long distance boyfriend has a cold sore and I'm seeing him this weekend- can I kiss his face and can he kiss my face? Like cheek/forehead not mouth

It depends...: Is the diagnosis certain? Facial herpes can occur, but less common than oral (lips, etc), and it is unusual to have outbreaks in two area, i.e. both cheek and forehead. If he has it and you do not, best to avoid kissing and other direct contact, e.g. no oral sex on you. You could have a blood test. If already positive for HSV1 (as are half of all people), you're immune, can't catch it again. ...Read more

My boyfriend and I have oral herpes. I had a cold sore last night barely appearing, he kissed me then performed oral sex... am I in danger of genital?

Yes: Herpes can be transmitted to the genial area by oral sex. Since this would not be a primary out break because you already have oral herpes, the symptoms would be less severe than described for primary herpes. ...Read more

Can a child with a cold sore be spreading the virus if playing in a community pool?

Can a child with a cold sore be spreading the virus if playing in a community pool?

Possibly: Although community pools are chlorinated to help kill germs and prevent the spread of germs, the virus that causes cold sores is contagious. I suspect the risk is low. Nonetheless, I would suggest that kids with open, active cold sores stay out of community pools to help reduce the risk of transmission. ...Read more

If you have the virus but no outbreak, is it possible to give the cold sore to someone else?

Cold sores: Because you can shed the virus without having open lesions, you should always let your partner know if you had cold sores in the past. Still, you are more likely to spread the virus when a sore is visible to that would be the time to avoid contact until the sore is completely gone. ...Read more

If I took a sip from a friends straw but she didn't have a cold sore or anything and I don't know if she gets them how long can the virus live on astraw?

Herpes: 75% of americans have herpes. It is more likely that you are already have herpes than not. If you have not had the blood test for herpes then that has to happen before you worry about other infections. But, in this scenario it is possible if there is immediate exposure to your friend's straw to getting virus if they have herpes. There is no standard time to consider. Please get tested. ...Read more

My husband cheated for 4 months and now I have a cold sore for the first time ever and I'm 39. He does not have a cold sore. Could he give me the virus without him ever getting a cold sore.

Cold: Cold sores or fever blisters are caused by herpes simplex virus type 1 (hsv-1) and are extremely common. Most people become infected as an infant or small child when kissed or by sharing eating utensils with an adult who has the virus. The virus is most contagious when someone has a cold sore, but can still be passed along by someone who does not. Many people do not even know that they are infected because the virus can "hide out" in the nerve cells for very long periods of time - for some people it hides out forever and they never get a cold sore. For others, the virus can "wake up" and that's when a cold sore happens. No one knows exactly what causes a cold sore to appear - sometimes stress, illness, fevers, colds, sunlight, cold weather, menstruation, certain foods, allergies, you name it! They usually last 7-10 days and are more of an annoyance than a danger unless you have a weakened immune system or contract a bacterial infection on top of the cold sore.

So yes, your husband could have given you hsv-1 without ever having a cold sore himself. However, it is also possible that you could have caught hsv-1 years ago from someone else by kissing or sharing eating utensils and are just now having symptoms. (possibly brought out by recent stress?) since the virus is so common and lies dormant in so many people, it can be difficult to pinpoint the source of infection. ...Read more
