Can you still get infected with genital herpes during sex if the other person is not having a out break?

absolutely. with most infectious diseases you can get infected when no signs are evident at the given time.

Yes..most people get herpies from their partners when they have no signs and symptoms of outbreak...
Yes. I just saw the commercial for valtrex. You can still pass genital herpes along even if you are not having an outbreak.
Hello, they advertise this on TV all the time to get you to buy valtrex.
Do you not own a T.V.? The answer to this question is answered on T.V. all the time. But just in case here is some info that backs up the info given in the commercial.

FACTS ABOUT GENITAL HERPES:
Transmission is caused by close oral, anal, or genital contact, including intercourse, masturbation, kissing, or any direct skin-to-skin contact which allows for the transfer of bodily fluids.

A person is considered contagious when prodromal symptoms, active sores, and healing lesions are present.

Herpes is potentially contagious when no symptoms are present. That is, a person who has genital herpes is potentially always shedding active virus.

Approximately 1 in 6 members of the general infected population is thought to shed active virus occasionally without symptoms.

Some people do not get typical blister-like sores but harbor active virus in their saliva, vaginal, or penile secretions, and can shed the virus without knowing they have herpes.

Lesions can occur deep inside the vagina where they cannot be seen or felt, but can readily transmit the virus.

An uninfected individual has about a 75% chance of contracting herpes during intimate contact with someone actively shedding virus.

Oral herpes can be transmitted to the genitals, and vice versa. Symptoms are similar.

Auto-inoculation: An infected individual can spread the virus to other parts of his or her body by touching an area shedding virus and then touching, scratching, or rubbing another susceptible part of the body. Towels are especially conducive to this.

It is possible for a person to contract genital herpes if the partner with oral herpes performs oral sex. Oral herpes can be transmitted to the genitals, and vice versa. Symptoms are similar.

Environmental surfaces like toilet seats may be a source of contagion, but there is no evidence that this poses a real threat to the general population. Experts differ as to how long the virus can survive on its own. The primary cause of infection remains intimate contact.

Yes. If you think about it logically, would a smart person actually have sex with someone who had an outbreak that was obvious to the naked eye? Probably not. Therefore, of course it is transmittable without having an outbreak.
