Talk with your partner about STIs before
beginning a sexual relationship. Find out whether he or she is at risk for an
STI. Remember that it is quite possible to have an STI without
knowing it. Some STIs, such as
HIV, can take up to 6 months before they can be

relationship who takes the
antiviral medicinevalacyclovir daily to prevent
recurrent outbreaks also reduces the risk of infecting his or her
partner.2 Other antiviral medicines may also reduce
transmission, but further study is needed.
Condom use reduces the risk of

Genital herpes and pregnancy
A woman who gets
genital herpes while she is pregnant is at risk of passing the infection to her

the virus that most commonly causes cold sores. Most experts advise pregnant
women not to receive oral sex in the last three months of their pregnancy. It
increases their risk of genital infection with HSV-1.
Antiviral medicine can be used safely in pregnancy to reduce
the number of outbreaks or shorten the length of an outbreak.
Acyclovir (Zovirax) is used in the last 4 weeks
of pregnancy to reduce the risk of a recurrent outbreak at the time of delivery. This lower risk, in turn, makes it less likely that delivery by cesarean section will be needed.
