Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are common health conditions worldwide. Millions of people are diagnosed with at least one STD every year in the United States.

STDs are most likely to be spread by sexual contact including vaginal, anal or oral sex. Some STDs can even spread through intimate rubbing or grinding and non-sexual means such as through blood or blood products.

How to prevent STDs

Some sexually transmitted diseases (STDs) have no cure, whereas others may cause infertility. Hence, prevention is the key that can be done by following safe sex practices. Here are the important ones.

Use condoms and dental dams during sex while ensuring they stay in place
Limit sexual activities to only one person
Avoid casual sex

Be aware of the modes of transmission of STDs. You can gather knowledge from reliable sexual health education sources.

If you have an STD, you may have no symptoms at all initially or have mild symptoms. Do not hesitate to get tested if you feel you are at risk of STDs.

Get vaccinated. It can help prevent STDs.

Having one STD also makes you more likely to get another STD. Discuss the risks with your doctor.

Share the status of your sexual health with your partner and encourage them to do the same. Seek early treatment if tests come out to be positive for any STD and encourage your partner to get tested and treated early.
