Herpes is a common viral infection caused by the herpes simplex virus (HSV). There are two main types: herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2).

HSV-1 is typically associated with oral herpes, which causes cold sores or fever blisters around the mouth and on the face. HSV-2 is primarily responsible for genital herpes, characterized by sores, blisters, or ulcers in the genital area.

Herpes is highly contagious and can be transmitted through direct contact with the sores or secretions from an infected person during oral, genital, or anal sex. It can also be transmitted through skin-to-skin contact, even in the absence of visible sores.

HPV is a common sexually transmitted infection caused by the human papillomavirus.

There are over 100 different types of HPV, and some strains can cause genital warts, while others are linked to various cancers, including cervical, anal, penile, vulvar, vaginal, and throat cancers.
HPV is spread through skin-to-skin contact during vaginal, anal, or oral sex with an infected person. It can also be transmitted through other forms of intimate skin-to-skin contact, such as genital touching.

Many people with HPV do not experience any symptoms and may unknowingly transmit the virus to others. However, some strains can cause genital warts, which are small, flesh-colored bumps or growths in the genital area.

Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum.

It can be transmitted through direct contact with a syphilis sore during vaginal, anal, or oral sex, as well as through pregnancy from mother to baby (congenital syphilis).

Syphilis progresses through different stages if left untreated: primary (characterized by painless sores or ulcers at the site of infection), secondary (marked by skin rashes, mucous membrane lesions, and flu-like symptoms), latent (where the infection remains dormant with no symptoms), and tertiary (which can lead to severe complications affecting the heart, brain, nerves, and other organs).

Gonorrhea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae.

It can infect both men and women and is most commonly spread through unprotected vaginal, anal, or oral sex with an infected person. Symptoms of gonorrhea can include painful urination, abnormal genital discharge (yellowish or greenish), and genital itching or soreness.

However, many people with gonorrhea may not experience any symptoms. If left untreated, gonorrhea can lead to serious health complications, such as pelvic inflammatory disease (PID) in women, infertility in both men and women, and an increased risk of contracting or transmitting HIV.

Hepatitis C is a viral infection caused by the Hepatitis C virus (HCV), which primarily affects the liver.

Hepatitis C is a viral infection caused by the Hepatitis C virus (HCV), which primarily affects the liver. Hep C is usually transmitted through exposure to infected blood. This can occur through sharing needles or other equipment used for injecting drugs, receiving blood transfusions or organ transplants before widespread screening, or through needlestick injuries in healthcare settings. It can also be transmitted sexually, although this is less common.

Many people with Hepatitis C may not experience symptoms for years or even decades. When symptoms do occur, they can include fatigue, jaundice (yellowing of the skin and eyes), abdominal pain, loss of appetite, nausea, and dark urine.

Chronic Hepatitis C can lead to serious liver problems over time, including cirrhosis (scarring of the liver), liver failure, and an increased risk of liver cancer.
