Can you get sexually transmitted diseases without having sex?

cause i was watching degrassi and some kid was born HIV positive and i dont see how that works.

In this day and age, it is very rare for children in the industrialized world (USA, Canada, UK, Japan, Australia, etc) to be born with HIV. However it happens a LOT in places like Africa and India.

HIV can be passed from a HIV+ mom to her baby during pregnancy. The chances of a HIV+ mom giving birth to a HIV+ baby are about 1 in 3 if she is not given medicine to treat the HIV. In industrialized countries, HIV+ moms are given medication during pregnancy, and then the baby is given medicine after it is born. Also, the HIV+ mom is instructed NOT to breastfeed. Breastmilk can have HIV in it. These measures have cut the rate of children being born with HIV to almost nothing.

If a mom doesn't get tested for HIV and doesn't know that she has it, then the baby could get HIV that way. These days, most women get HIV tests as part of their prenatal care.

There are other STDs that spread from mom to baby include Hepatitis B. It is very common in Asia; moms pass the Hep B virus to their kids, and their kids become carriers. They can spread it later in life via sex or blood exposure. Hepatitis B can also be spread by sharing toothbrushes and shaving razors.

And "sex" can be a vague term. Some people wouldn't consider dry humping to be real sex, but if you do it without clothes on, you can contract herpes and HPV. Other STDs can be contracted via oral sex, which some people don't consider to be real sex, but it still poses a STD risk anyway.

No, you can never have this diseases unless you never had intercourse, and some of the children's born that already infected of HIV that is because of their parents had already infected before they became a pregnant. HIV diseases can infect you through saliva and for having sex to the person that already infected of this.

you can only be born with an STD if your mom has it. otherwise define "sex"

do you mean sexual intercourse
because there are 4 ways you can get sexually transmitted diseses
1. Sex
2. Oral Sex
3. Anal Sex
4 Mutual Masturbation(touching someones genital area who has herpes, with your hands.)
